v1.6.0 - July 18, 2005
* Included new file phpThumb.demo.random.php to select a
random image from a specified folder, optionally only
landscape and/or portrait and/or square images, and to
display it to phpThumb.php
(thanks mikeØgdaymate*nl)
* Added /docs/phpthumb.faq.txt
* Added /demo/readme.demos.txt
* Added 'wp', 'hp', 'wl', 'hl', 'ws', 'hs' parameters for
width and height of portrait, landscape and square
images. This allows you to display any image aspect
ratio at the size you want without knowing ahead of time
whether the image is wide or tall.
(thanks mikeØgdaymate*nl)
* phpThumb.php can now also be called by passing parameters
in $_SERVER['PATH_INFO']. Please see phpthumb.readme.txt
(thanks javierØguegue*net)
* MySQL data pulling configuration moved from phpThumb.php
to phpThumb.config.php
* "file" and "goto" parameters are now disabled by
default (configurable in phpThumb.config.php but not
recommended)
* Cached files are now used from first instance, avoiding
call to OutputThumbnail and preventing browser-side
cache failure
* Added config_allow_src_above_docroot (default=false) to
prevent browsing filesystem outside document_root
(thanks davidØint0x80*com)
* Added config_allow_src_above_phpthumb (default=true) to
prevent access to files except in subdirectories of
phpThumb installation (thanks davidØint0x80*com)
* Added setParameter() and getParameter() functions
(thanks werner*kraussØhallstatt*net)
* SafeBackTick() renamed to SafeExec() and all execution
functions are tried (exec, shell_exec, system, passthru)
are tried in case one or more are disabled
(thanks bkainersØgmail*com)
* config_output_allow_enlarging has been removed from
phpthumb.class.php, and 'output_allow_enlarging' has
been removed from phpThumb.config.php
* New default detection method for
$PHPTHUMB_CONFIG['document_root']
* Bugfix: inconsitant handling of boolean parameters
passed "0" (isset vs !empty()) (thanks manniØzapto*de)
* Bugfix: text watermarks now support multiple lines
(thanks hanno*vandenbergØhccnet*nl)
* Bugfix: suppress error message in
ImageCreateFromStringReplacement()
(thanks srimandadapuØyahoo*com)
* Bugfix: 'aoe' was ignored in object mode
(thanks tonyØnylink*com)
* Bugfix: ResolveFilenameToAbsolute() failed on non-
existant filenames (file to be written, for example)
* Bugfix: 'aoe' parameter was ignored in cache filename
(thanks tonyØnylink*com)
* Bugfix: non-TTF watermark text had inverted opacity
scale. All 'wmt' is now 100=opaque, 0=transparent
(thanks mailØmmjaeger*com)
* Bugfix: cache file failed if document_root had
trailing slash. (thanks lovingloboØgmail*com)
* Bugfix: [#1219422] Cache filename structure modified to
avoid excessively long filenames (cache filenames are
now limited to 142 characters + length of
$_SERVER['SERVER_NAME'])
(thanks trungieØusers*sourceforge*net)
* Bugfix: [#1211729] phpThumb.php fails to locate
phpThumb.config.php if the two files are in the same
directory but phpThumb.php is run through a sym link.
(thanks allanbushØusers*sourceforge*net)
v1.5.4 - May 27, 2005
* Security issue with passthrough addressed
(thanks davidØint0x80*com)
* 'wmt' now reads TTF fonts from the config font
directory, or from anywhere if a path is specified in
the font filename
(thanks mailØmmjaeger*com)
* Changed default error_die_on_source_failure to true in
phpThumb.config.php
* Bugfix: Firefox (possibly other browsers) did not like
the new (faster) cache retrieval method with Location
header redirection if the cached filename does not have
a recognized filename extension (.jpeg, .png, .gif).
Cached images have therefore been renamed from *_jpeg to
*.jpeg and the _qXX parameter has been removed for PNG
and GIF output. Please use the included cache renamer:
/demo/phpThumb.demo.cacheconvert2.php
(thanks mailØmmjaeger*com)
* Bugfix: Changed "Content-type" to "Content-Type" in all
header calls
* Bugfix: 'wmt' text opacity was broken
(thanks mstuhuØweb*de)
* Bugfix: variable name typo in phpThumb.demo.object.php
(thanks mbØmarko-bischof*de)
* Bugfix: no GD support for source image format now
reported as such for remote images
(thanks andgu842Østudent*liu*se)
* Bugfix: very narrow images no longer produce Invalid
Image Dimensions error (thanks mailØmmjaeger*com)
v1.5.3 - May 4, 2005
* Added new filters:
- 'wb' (White Balance) [ex: &fltr[]=wb|<c>]
where <c> is the target hex color to white balance
on, this color is what "should be" white, or light
gray. The filter attempts to maintain brightness so
any gray color can theoretically be used. If <c> is
omitted the filter guesses based on brightest pixels
in each of RGB
* Cached files are used by a Location header instead of
being passed through phpThumb.php using readfile
(thanks newtnØthrillnerds*com)
* Added 'cache_source_filemtime_ignore_local' and
'cache_source_filemtime_ignore_remote' configurations
to ignore source modification and/or removal
(thanks raynerapeØgmail*com)
* Added 'md5s' parameter, which is the MD5 hash of the
source image -- if this parameter is passed with the
hash of the source image then the source image is not
checked for existance or modification and the cached
file is used (if available). If 'md5s' is passed an
empty string then phpThumb.php dies and outputs the
correct MD5 hash value. This parameter is the single-
file equivalent of 'cache_source_filemtime_ignore_*'
configuration paramters (thanks raynerapeØgmail*com)
* Added /demo/phpThumb.demo.object.php
* Unused parameter 'bgt' removed
* Added empty /cache/source/ directory to distribution
* Added /demo/ and /docs/ and /fonts/ directories
* Set default config_use_exif_thumbnail_for_speed = false
* Bugfix: Wrapped output buffering around all
include_once calls to prevent headers getting sent
accidentally
* Bugfix: md5_file and imagecolorallocatealpha calls
were undefined under PHP v4.1.x (thanks tomØemile*com)
* Bugfix: default 'f' parameter ('jpeg') overrode
config_output_format in object mode
(thanks mailØmmjaeger*com)
* Bugfix: suppressed error message for IIS shell_exec
errors (thanks tomØemile*com)
* Bugfix: Added PHP version check for stream_set_timeout
for HTTP sources (thanks raynerapeØgmail*com)
* Bugfix: overlay margins of 0.5-1.0 cause invalid image
dimensions error (thanks mailØmmjaeger*com)
* Bugfix: underlay margins were not working
(thanks mailØmmjaeger*com)
* Bugfix: [#1187735] EXIF thumbnails were incorrectly
output to the browser directly if requested thumbnail
exactly matched EXIF dimensions
(thanks rebootØusers*sourceforge*net)
v1.5.2 - April 20, 2005
* phpThumb.config.php is renamed to
phpThumb.config.php.default to prevent accidental
overwriting. Please migrate your old settings to the new
file, delete your old config and rename the default to
phpThumb.config.php
* Added new filters:
- 'blur' (Blur) [ex: &fltr[]=blur|<radius>]
where (0 < <radius> < 25) (default = 1)
(thanks thoensiØnetcom*no for code)
- 'hist' (Histogram)
[ex: &fltr[]=hist|<b>|<c>|<w>|<h>|<a>|<o>|<m>]
Where <b> is the color band(s) to display, from back
to front (one or more of "rgba*" for Red Green Blue
Alpha and Grayscale respectively);
<c> is a semicolon-seperated list of hex colors to
use for each graph band (defaults to FF0000, 00FF00,
0000FF, 999999, FFFFFF respectively);
<w> and <h> are the width and height of the overlaid
histogram in pixels, or if <= 1 then percentage of
source image width/height;
<a> is the alignment (same as for "wmi" and "wmt");
<o> is opacity from 0 to 100;
<m> is the edge (and inter-tile) margin in percent
- 'over' (OVERlay/underlay image) overlays an image on
the thumbnail, or overlays the thumbnail on another
image (to create a picture frame for example)
[ex: &fltr[]=over|<i>|<u>|<m>|<o>]
where <i> is the image filename; <u> is "0" (default)
for overlay the image on top of the thumbnail or "1"
for overlay the thumbnail on top of the image; <m> is
the margin - can be absolute pixels, or if < 1 is a
percentage of the thumbnail size [must be < 0.5]
(default is 0 for overlay and 10% for underlay);
<o> is opacity (0 = transparent, 100 = opaque)
(thanks raynerapeØgmail*com, shabazz3Ømsu*edu)
- 'gray' (GRAYscale) [ex: &fltr[]=gray]
is an alias to 100% desaturation
* New configuration 'cache_source_directory' allows the
unprocessed source image to be cached when source is
HTTP or from a database (thanks raynerapeØgmail*com)
* Added 'cache' subdirectory to phpThumb distribution
since this is the default location for the cache
folder.
* Default value for config_error_die_on_source_failure
changed to true (thanks shabazz3Ømsu*edu)
* Added checks to make sure $this->gdimg_output is a
resource before allowing calls to RenderToFile or
OutputThumbnail
* Better error messages when phpThumb.config.php missing
* Bugfix: watermark overlay margins were wrong
* Bugfix: 'lvl' filter no longer processes if not needed
* Bugfix: off-server thumbnail error message was wrong
* Bugfix: several PHP safe mode fixes
(thanks virginiaØalertbutnotalarmed*com)
* Bugfix: cache filenames broken for filter parameters
with paths (thanks srcericØusers.sourceforge.net)
v1.5.1 - April 06, 2005
* Added some security upgrades:
- 'config_*' parameters cannot be passed by GETstring
- 'config_nooffsitelink_require_refer' is a new option
(disabled by default) that only allows calls to
phpThumb() from a refering domain listed in
'config_nooffsitelink_valid_domains'
- disallowed paramters now generate an error image if
present in the GETstring
- 'high_security_enabled' if set to true enabled new
mode of verification, and requires a small function
to generate a hash for calls to phpThumb:
echo '<img src="'.phpThumbURL('src=pic.jpg&w=50').'">';
This function is supplied at the bottom of
phpThumb.config.php (thanks paulØstonie*co*uk)
* Added new parameter "new" (phpThumb.php only) which can
create a new image without using "src" parameter. Set
"&new=<b>|<o>" where <b> is the background hex color,
<o> is (optional) opacity (0=transparent, 100=opaque).
(thanks mailØmmjaeger*com)
* Added new filters:
- 'sep' (Sepia) [ex: &fltr[]=sep|<value>|<color>]
where <value> is a number between 0 and 100 for the
amount of colorization (default=50), and <color> is
the hex color to colorize to (default=A28065).
(thanks mailØmmjaeger*com)
- 'lvl' (Levels) [ex: &fltr[]=lvl|<channel>|<min>|<max>
where <channel> can be one of 'r', 'g', 'b', 'a' (for
Red, Green, Blue, Alpha respectively), or '*' for all
channels based on average grayscale value (default).
<min> and <max> are the clip points for the levels
(range = 0-255) and are set to clip 0.1% of each end
by default. Use -1 for min and/or max to invoke auto-
detect mode. Using default parameters (&fltr[]=lvl)
is similar to Auto Contrast in Adobe Photoshop.
* Bugfix: Image MIME header was incorrect for cached
images.
* Bugfix: Cache was broken for images pulled from a
database in phpThumb.php
(thanks dragutin*cvetkovicØdragontech-ltd*com)
* Bugfix: Hotlink/Offsite prevention was broken when
image was already cached.
* Bugfix: ImageMagick path was incorrect in some cases
(thanks joshgØtwcny*rr*com)
* Bugfix: ProportionalResize() in phpthumb.functions.php
had a broken check for default values
(thanks Bert*ClaeysØarinso*com)
* Bugfix: transparency now preserved for GIF & PNG input
(thanks tristanØcyrax*ch)
* Bugfix: transparency now supported for GIF output
(thanks j_ivanovØabv*bg)
* Bugfix: alpha transparency could be lost in ApplyMask()
(thanks analyzerxØgmail*com)
* Bugfix: errors on 16/32-bit BMPs
(thanks mattØhellstrominc*com)
* Bugfix: Added datestamp to cached filenames for remote
(HTTP) files, and better warning for caching
(thanks a*gambinoØabramo*it)
* Faster BMP parsing (thanks sgeppertØmail*utexas*edu)
* Added 'error_die_on_source_failure' configuration to
allow invalid source images to show an error rather
than output unmodified source image.
(thanks mindpixelØgmail*com)
* Added $phpThumb->fatalerror which will contain the
text of the fatal error if 'error_die_on_error' is
false. (thanks mindpixelØgmail*com)
v1.5.0 - February 4, 2005
* Added new filter parameter 'fltr' that is an array and
can apply multiple effects in sequence. Current filters
that can be called are:
- 'gam' (Gamma Correction) [ex: &fltr[]=gam|<value>]
where <value> can be a number >0 to 10+ (default 1.0)
- 'ds' (DeSaturate) [ex: &fltr[]=ds|<value>]
where <value> is a number between zero (no change)
and 100 (complete desaturation -- grayscale), or it
can be a negative number for saturation boost.
(thanks mailØmmjaeger*com)
- 'clr' (Colorize) [ex: &fltr[]=clr|<value>|<color>]
where <value> is a number between 0 and 100 for the
amount of colorization, and <color> is the hex color
to colorize to. (thanks mailØmmjaeger*com)
- 'neg' (Negative) [ex: &fltr[]=neg]
inverts the color
- 'th' (ThresHold) [ex: &fltr[]=th|<val>] (range 0-255)
every grayscale pixel brighter than <val> is set to
white, every darker pixel is set to black
(thanks mailØmmjaeger*com)
- 'usm' (UnSharpMask) [ex: &fltr[]=usm|<a>|<r>|<t>]
where <a> is the amount (default = 80), <r> is the
radius (default = 0.5), <t> is the threshold
(default = 3).
- 'wmi' (WaterMarkImage)
[ex: &fltr[]=wmi|<f>|<a>|<o>|<m>] where <f> is the
filename of the image to overlay, <a> is the
alignment (one of BR, BL, TR, TL, C, R, L, T, B, *
where B=bottom, T=top, L=left, R=right, C=centre,
*=tile), <o> is opacity from 0 to 100, <m> is the
edge (and inter-tile) margin in percent
- 'wmt' (WaterMarkText)
[ex: &fltr[]=wmt|<t>|<s>|<a>|<c>|<f>|<o>|<m>|<n>]
where:
<t> is the text to use as a watermark,
<s> is the font size (1-5 for built-in font, or point
size for TrueType fonts),
<a> is the alignment (one of BR, BL, TR, TL, C, R, L,
T, B, * where B=bottom, T=top, L=left, R=right,
C=centre, *=tile),
<c> is the hex color of the text
<f> is the filename of the TTF file (optional, if
omitted a built-in font will be used)
<o> is opacity from 0 to 100,
<m> is the edge (and inter-tile) margin in percent
<n> is the angle
(thanks mailØmmjaeger*com)
- 'flip' [ex: &fltr[]=flip|x or &fltr[]=flip|y]
flip image on X or Y axis
(thanks mailØmmjaeger*com)
- 'elip' [ex: &fltr[]=elip]
similar to rounded corners but more extreme
(thanks mailØmmjaeger*com)
- 'mask' [ex: &fltr[]=mask|filename.png]
greyscale values of mask are applied as the alpha
channel to the main image. White is opaque, black
is transparent.
- 'bvl' (BeVeL) [ex: &fltr[]=bvl|<w>|<c1>|<c2>]
where <w> is the bevel width, <c1> is the hex color
for the top and left shading, <c2> is the hex color
for the bottom and right shading
(thanks mailØmmjaeger*com)
- 'fram' (FRAMe) draws a frame, similar to border but
more configurable (thanks mailØmmjaeger*com)
[ex: &fltr[]=fram|<w1>|<w2>|<c1>|<c2>|<c3>]
where <w1> is the width of the main border, <w2> is
the width of each side of the bevel part, <c1> is the
hex color of the main border, <c2> is the highlight
bevel color, <c3> is the shadow bevel color
- 'drop' (DROP shadow)
[ex: &fltr[]=drop|<d>|<w>|<clr>|<a>]
where <d> is distance from image to shadow, <w> is
width of shadow fade (not yet implemented), <clr> is
the hex color of the shadow, and <a> is the angle of
the shadow (default=225)
- 'ric' (Rounded Image Corners)
[ex: &fltr[]=ric|<x>|<y>]
where <x> is the horizontal corner radius,
<y> is the vertical corner radius
* Split out filter functions into phpthumb.filters.php
* 'usa', 'usr', 'ust' parameters have been removed and
replaced with the 'fltr' call (see above)
* 'wmf', 'wma', 'wmp', 'wmm' parameters have been removed
and replaced with the 'fltr' call (see above)
* 'brx', 'bry', 'bw' parameters have been removed
and replaced with the 'fltr' call (see above)
* 'bw=0' to force aspect ratio has been replaced by
'far=1' (force aspect ratio)
* Filters that produce transparent sections (such as
Rounded Corners, Ellipse, Mask, Rotate) are now output
as 32-bit/alpha PNG, or flattened with "bg" background
color for JPEG/GIF output (thanks mailØmmjaeger*com)
* Added 'zc' (Zoom Crop) parameter
(thanks arcookeØgmail*com, mailØmmjaeger*com,
pl16056Ømacnews*de, kezzasmØusers*sourceforge*net, etc)
* AutoRotate now can use EXIF orientation tag ('ar=x')
* Added 'ttf_directory' configuration parameter for
TrueType watermarks (thanks mailØmmjaeger*com)
* Added "Last-Modified" header to cache portion of
phpThumb.php which should allow better user-side
caching of thumbnails. (thanks derekØnetsimple*net)
* Added 'cache_disable_warning' configuration which will
cause an error image to be displayed if the cache
directory isn't configured, unless explicitly disabled
* Added 'nooffsitelink_enabled' configuration which
prevents linking to thumbnails on your server from
another domain. Defaults to watermaking linked images
with text warning message.
(thanks anteØabstraktmedia*com)
* Added 'error_image_width' & 'error_image_height'
config variables (thanks mailØmmjaeger*com)
* Rounded image corners now requires GD v2.0.1 and PHP
v4.3.2. Corners are transparent (for PNG output) and
antialiased.
* Rotate by arbitary angle ('ra') now has a transparent
background for PNG output
* Cached filenames now have an additional component for
applied filters
* Cached filenames now have an additional component for
HTTP referer, but only if the refering domain does not
match the domain of the server (designed to prevent
imaged linked from offsite with error message being
cached the same as the local cached version)
* Added setSourceImageResource() to allow use of an
existing GD image resource for thumbnailing
(thanks danØgonmad*co*uk)
* Now including phpThumb.demo.demo1.php (main demo page)
and phpThumb.demo.demo2.php (configurable demo page)
in the phpThumb() distribution
(thanks mailØmmjaeger*com)
* Added many more debugging/tracing message points
* Added set_time_limit(30) to phpThumb.php
* Bugfix: ImageMagick not used if `which convert` points
to a link and not a file (thanks bkainersØgmail*com)
* Bugfix: 'bgt' parameter was sometimes misspelled 'bct'
* Bugfix: 'wmm' couldn't be set to zero
* Bugfix: 'wmm' parameter was only applied to top/left of
image
* Bugfix: auto-detection of document_root failed on
Windows (thanks xbartvØhotmail*com)
* Bugfix: phpThumbDebug could be bypassed if EXIF
thumbnail present (thanks olgradinØcheckfree*com)
* Bugfix: cache file wasn't being written if EXIF data
was used directly (thanks olgradinØcheckfree*com)
* Bugfix: phpThumb.demo.showpic.php was broken by popup
blockers for images larger than the screen.
(thanks mailØmmjaeger*com)
v1.4.11 - October 11, 2004
* Changed sx/sy/sw/sh parameters to allow decimal values
(>0 but <1) to represent percent of source image
(thanks mordorØdefault*co*yu)
* Added config_error_silent_die_on_error for no-output
die on fatal errors (thanks johannesØformformat*se)
* Added auto-detection of probable 'document_root' if
that key is not available in $_SERVER
* Bugfix: Check `which convert` failing with error
message (thanks chadØchadshome*com)
* Bugfix: Image cropping to invalid areas outside source
image caused text output (thanks mordorØdefault*co*yu)
v1.4.10 - August 22, 2004
* Bugfix: cached files not written in most cases
(thanks kizerØcourtkizer*com, snuffØinbox*ru)
* Bugfix: ApacheLookupURIarray() crashes in CGI mode
(thanks hanskrentelØyahoo*de)
* Bugfix: phpthumb_bmpfile2gd() was broken
(thanks iØmindlace*net)
v1.4.9 - August 9, 2004
* Bugfix: changed destination filename in RenderToFile()
(thanks alextkØwalla*com)
* Bugfix: problems with HTTP image source when called as
an object (thanks alextkØwalla*com)
v1.4.8 - August 4, 2004
* $this->error has changed to $this->errors and is now
an array of strings (instead of a single string)
* A lot more error conditions (invalid cache directory,
etc) are now reported in $this->errors
(thanks aidan*slingsbyØlineone*net)
* Removed all define(CONSTANT) in the phpThumb()
constructor - you can now access:
- PHPTHUMB_VERSION == $this->phpthumb_version;
- PHPTHUMB_OSSLASH == $this->osslash;
- PHPTHUMB_ISWINDOWS == $this->iswindows;
* Bugfix: Error message from apache_lookup_uri() failing
under Apache2 now reported cleanly
(thanks derbaffØyahoo*com)
* Bugfix: missing phpthumb_functions:: class name for
ImageTypeToMIMEtype() call in ExtractEXIFgetImageSize()
(thanks aidan*slingsbyØlineone*net)
* Bugfix: ImageTypeToMIMEtype() was broken for PHP older
than v4.3.0 (thanks georg*schreiberØbatch-pc*es)
* Bugfix: RenderToFile() now returns false if it fails
(thanks phpthumbØsendthemtomir*com)
* Bugfix: Corrupt JPEG/PNG/GIF files that failed
ImageCreateFrom*() were not being passed to ImageMagick
for fallback, nor passed through unmodified if IM was
unavailable or failed (thanks r*chongØmogenic*net)
* Bugfix: Improved backtick safe-mode limit detection
(thanks 1Øadamcarrington*com)
* Bugfix: EXIF thumbnails were being used as source when
they should not be (thanks aidan*slingsbyØlineone*net)
* Bugfix: Cached files were not being created or used
properly (thanks aidan*slingsbyØlineone*net)
* Bugfix: max_source_pixels not set correct on some PHP
versions (thanks derbaffØyahoo*com)
* Bugfix: 'down' parameter ignored for unprocessed and
cached files (thanks aidan*slingsbyØlineone*net)
v1.4.7 - July 27, 2004
* Included a modified version of "module.graphic.bmp.php"
from getID3() [http://getid3.sourceforge.net] as
"phpthumb.bmp.php" for BMP reading support without
ImageMagick. It works, but it's *very* slow, especially
for large images (as in 640x480 or larger).
* Added check to prevent error messages when shell_exec
is disabled (thanks webmasterØneester*com)
v1.4.6 - July 22, 2004
* Added new section to phpthumb.config.php where you can
easily specify defaults for any parameter you can set
in the URL. Normally URL parameters override these
default values, unless you set
$PHPTHUMB_DEFAULTS_GETSTRINGOVERRIDE to false
* Renamed phpthumb.config.php to phpThumb.config.php
since it's part of phpThumb.php, not part of
phpthumb.class.php (change of case only, will not
affect Windows servers, but will affect *nix)
* Changed cached filename of rawImageData-source images
from urlencode('') to md5(rawImageData). This should
make caching thumbnails from non-file sources more
reliable.
* Added ImageMagick debugging information
* Removed unneccesary default values from cached
filenames. This may invalidate some previously cached
files. phpthumb.demo.cacheconvert.php has been updated
to handle v1.4.1-1.4.5 => v1.4.6+ cache filenames.
* Bugfix: Cached filename did not have file-modified
datestamp when used as implmented in phpThumb.php
* Bugfix: RenderToFile() now accepts relative filenames
(thanks aidan*slingsbyØlineone*net)
* Bugfix: AllowOutputEnlargment setting was ignored when
falling back to ImageMagick
* Bugfix: IgnoreAspectRatio setting was ignored when
falling back to ImageMagick
* Bugfix: config_temp_directory was ignored in gd_info()
in PHP < v4.3.0 when phpinfo() returns no GD
information (due to safe mode restrictions)
(thanks mimyrtekØmyrtek*com)
v1.4.5 - June 28, 2004
* Added new parameter 'down' where you can specify a
filename and OutputThumbnail() will cause the file
to be downloaded rather than displayed in the browser.
Demo images on silisoftware.com/scripts/phpThumb/demo/
can all be downloaded to show off this feature.
(thanks stuartscrumpØyahoo*co*uk)
* Added ability to remove old files from cache directory
based on last-access time and/or number of cached files
and/or total size of cached files
(thanks jrmhaigØyahoo*co*uk)
* Added public CleanUpCacheDirectory() for cache cleaning
(see above) if you need to call it manually
* Included new file phpThumb.demo.cacheconvert.php to
convert old-style cache names to the current (and
hopefully last!) standard naming convention.
(thanks joshgØtwcny*rr*com)
* Added configuration value 'document_root' for rare case
when $_SERVER['DOCUMENT_ROOT'] return incorrect value
(thanks joshgØtwcny*rr*com)
* Now tries to create thumbnail with ImageMagick if
ImageCreateFromJPEG etc fails, before falling back to
outputting unmodified source data.
* Bugfix: HTTP image sources were broken
(thanks fritz*weisshartØt-online*de)
* Bugfix: ImageMagick callout wasn't being used if EXIF
thumbnail was available
(thanks joshgØtwcny*rr*com)
* Bugfix: HTTP src with space in filename was broken
(thanks drØrhodes360*com)
* Bugfix: version_compare_replacement() was broken for
PHP v4.1.0+
v1.4.4 - June 8, 2004
* Bugfix: network-share (Windows) source filenames were
not possible. Now works, but you must use the network
name and not a mapped drive name, for example:
\\othercomputer\file.jpg - good
\\192.168.2.1\file.jpg - good
z:\file.jpg - won't work
This is a PHP limitation (see www.php.net/file-exists)
Note: you may want to use "/" slashes instead of "\" if
you have magic_quotes_gpc enabled to avoid stripslashes
problems.
(thanks drØrhodes360*com)
* Bugfix: missing "phpthumb_functions::" in
ImageCreateFromStringReplacement()
(thanks zapletalØsoftwaremedia*cz)
v1.4.3 - May 25, 2004
* Added new configuration variable 'config_temp_directory'
to allow you to specify a writable directory name for
temp files if you do not have access to the system temp
directory on your server (Safe Mode restrictions etc)
(thanks nickØregenmag*com)
* Added new configuration variable
'config_error_die_on_error' which can be set to false if
you want to retrieve the error message without having it
dumped as an image - the error message is now available
in $phpThumb->error
* Images are passed through directly with no processing
and no caching if no parameters are passed to alter the
image (resize, crop, sharpening, etc)
(thanks nchmuraØusers*sourceforge*net)
* Added new configuration variable 'config_disable_debug'
which disabled phpThumbDebug from working if you have
security concerns about the displayed information
* Bugfix: Added detection at the top of phpThumb.php for
no-GD errors to avoid parse errors later in the code
(thanks nickØregenmag*com)
* Bugfix: RoundedImageCorners() had some off-by-1 errors
(thanks ola*thunbergØhome*se)
v1.4.2 - May 10, 2004
* Added IE-compatability mode for transparent corners
(set 'bct=256')
* Bugfix: version_compare_replacement() was broken in PHP
older than 4.1.0
(thanks nickØregenmag*com)
v1.4.1.1 - May 9, 2004
* Bugfix: Removed ImageTrueColorToPalette hack.
See http://bugs.php.net/bug.php?id=28341
* Bugfix: 'maxb' option for PNG/GIF output incorrect
bit depth under some circumstances
v1.4.1 - May 9, 2004
* Added 'maxb' (MAXimum Bytes) option to auto-set the
output image quality (JPEG) or bit depth (PNG/GIF) so
that the output thumbnail is less than 'maxb' bytes
(thanks e_belleØhotmail*com)
* Added 'bgt' parameter to make rounded corners from
'brx'/'bry' option transparent when used with PNG
output. Note: PHP/GD appears buggy at this time, so this
option must force output to 256-color mode for this
to work. The feature will be updated when a non-broken
version of PHP/GD is released.
(thanks javierØircorion*net)
* Bugfix: Caching was broken
(thanks mikeØgdaymate*nl, jurewiczØgo3*pl)
v1.4.0 - April 30, 2004
* Rewritten as a PHP class. Split into several files:
- phpthumb.class.php = most processing code
- phpthumb.functions.php = support functions
- phpthumb.readme.txt = usage instructions
- phpthumb.changelog.txt = this file
- phpthumb.config.php = configuration file
- phpthumb.gif.php = Non-GD GIF reading support
- phpthumb.unsharp.php = Unsharp Masking support
- phpThumb.php = demo script that works
exactly as previous versions; this is a drop-in
replacement for existing phpThumb() installations
- phpThumb.demo.showpic.php = demo script that auto-
resizes a popup window to the size of the image
shown. Useful if you want popup images but do not
know the large image size beforehand
* Added optional call-out to ImageMagick (if avaible) if
source image is larger than PHP memory restrictions
allow. ImageMagick installation should be auto-detected
under *nix, but you should configure 'imagemagick_path'
for use under Windows.
* 'max_source_pixels' is now auto-calculated from PHP
configuration settings. Due to various server-level
restrictions that may override PHP settings this
calculated value may not always be correct, and you may
have to specify the value manually.
* Added rounded-corner border option. You must specify
both 'brx' (horizontal radius) and 'bry' (vertical
radius) as well as 'bw' (border width). If 'bw' is
greater than zero, the image will be shrunk to fit
inside the border with a margin of background color.
If 'bw' is zero, the corners of the image will be
cut off and filled with background color.
(thanks javierØircorion*net)
* Minor speed improvement for unsharp masking
v1.3.7 - March 28, 2004
* Bugfix: GD version detection was broken on PHP <4.3.0
on servers where phpinfo() was disabled
(thanks javierØircorion*net)
* Bugfix: Non-GD GIF support was broken on restricted
PHP configurations
(thanks javierØircorion*net)
* Bugfix: phpThumb.gif.php output error messages if PHP
was running in Safe Mode
* Added 'iar' parameter (Ignore Aspect Ratio) to allow
non-proportional resizing (stretch image to fit).
You must specify 'h' and 'w' to use this option.
(thanks javierØircorion*net)
v1.3.6 - March 14, 2004
* Bugfix: was broken when register_globals turned on
(thanks joshgØtwcny*rr*com)
* Bugfix: Images with transparent backgrounds now have
the background color filled with the color specified
by the 'bg' parameter
* Bugfix: ImageCreateFromString() is broken in the
non-bundled GD. Added workaround, but please use
the bundled version of GD if possible
(thanks dnØxbe*ch)
* Bugfix: EXIF thumbnail caching was broken
* Bugfix: EXIF thumbnail handling was broken for PHP
v4.2.x
(thanks smithk1Øshaw*ca)
* Bugfix: Image borders with GD2 were misaligned
* Bugfix: virtual paths/filenames like /~user/foo.jpg
should now work properly, if PHP is installed as an
Apache module (see www.php.net/apache-lookup-uri)
* Bugfix: contents of any non-image file could be
displayed (including PHP & HTML files)
(thanks arsyanØarsyan*com)
* Added rotation parameters 'ra' and 'ar'
(thanks drØrhodes360*com)
* Added $CONFIG['output_allow_enlarging'], defaulted
to false, to prevent smaller-than-max-size images
from being enlarged beyond their original size. If
you want to be able to enlarge images, set this to
false. Can be overridden with the 'aoe' parameter
(thanks dnØxbe*ch)
* Changed all configuration variables to be under one
array named $CONFIG
* Moved color and font options for ErrorImage() to
$CONFIG variables
* Changed cached filename structure (again) to a more
flexible format that can handle future expansion
(old cached files are invalid and will be recreated)
* Added more debugging code to phpThumbDebug
v1.3.5 - February 29, 2004
* Added capability to use EXIF thumbnail that may be
embedded in source image (often is in digital camera
JPEGs) and source image dimensions are larger than
$config_max_source_pixels. This will overcome the
limitation where PHP runs out of memory processing
large images (usually >1600x1200). EXIF thumbnail
extraction requires PHP v4.2.0 or higher and EXIF
support compiled into PHP (or php_exif extension)
* Eliminated intermediate read-file-to-memory stage if
image is created from local file. Should allow
larger images to be processed without running out of
memory.
* Added optional 'goto' parameter to be used with the
'file' parameter, where 'goto' is a URL that is
redirected to after image is rendered to file
(thanks wimbleØwebdonors*com)
* Added optional 'xto' parameter that will bypass all
processing and just return the embedded EXIF
thumbnail, if available.
* Added error-handling if ImageTypes() is unavailable
v1.3.4 - February 15, 2004
* Custom error image option (&err=img.jpg) which can
also be set as $config_error_message_image_default
(thanks carlØ4thstar*net)
* &f=text will now output plain-text error messages
* ErrorImage() now used for anti-hotlink messages (if
$config_nohotlink_erase_image is true)
v1.3.3 - February 5, 2004
* Bugfix: Added stripslashes() to filenames if
magic_quotes_gpc is enabled
(thanks arsyanØarsyan*com)
* Output can now be rendered to a file only (not to
browser) specified by the 'file' parameter
(thanks arsyanØarsyan*com)
* JPEG quality now has a maximum of 95%, as specified
in the GD documentation
v1.3.2.1 - February 3, 2004
* Bugfix: gd_version() was broken for GD v2.0+
* Bugfix: removed debugging code
v1.3.2 - February 3, 2004
* Bugfix: when borders are enabled, portait images
with no width constraint, or landscape images with
no height constraint were smaller than neccesary by
double the border width
(thanks jjjØxs4all*nl)
* Added unsharp mask option thanks to Torstein Hønsi:
http://www.vikjavev.com/hovudsida/umtestside.php
Note: requires GD v2.x to function
(thanks jjjØxs4all*nl)
* Updated cache filenames to reflect new parameters,
this means old cached files will need to be deleted
(or not, they just will never get called again) and
new cached versions will be created.
* Added caching to gd_info() calls for minor speedup
v1.3.1 - February 2, 2004
* Added optional border (width and color configurable)
(thanks arsyanØarsyan*com)
* Added option to create fixed-dimension thumbnails
regardless of source aspect ration. Set the 'bw'
(BorderWidth) parameter (even to 0) and this will be
enabled. Outside the actual image will be filled
with 'bg' color (default FFFFFF)
(thanks arsyanØarsyan*com)
v1.3.0 - January 27, 2004
* Added watermarking option to overlay thumbnails with
a semi-transparent watermark image (copied from a
seperate source watermark image)
(thanks arsyanØarsyan*com)
* Added option for absolute filenames (on both Windows
and *nix) outside the DOCUMENT_ROOT directory
* Added debug output dump for diagnosing problems)
v1.2.8 - January 19, 2004
* added ability to specify relative pathnames as well
as absolute pathnames (pathname is relative to the
location of phpThumb.php if the passed source does
not begin with "/"
v1.2.7 - January 7, 2004
* Added patch to allow use of PHP older than 4.1.0
(or GD without PNG support) for non-GD GIF support
(thanks hostwebserverØhotmail*com)
v1.2.6 - January 4, 2004
* Added patch to allow use of PHP older than 4.1.0
(without the superglobals arrays)
v1.2.5 - December 26, 2003
* Added configuration options for default output image
format and max width/height
v1.2.4 - December 20, 2003
* Bugfix: temp directory for non-native GD support not
always returning valid directory
* Caching feature reintroduced (see configuration)
v1.2.3 - December 19, 2003
* Added anti-hotlink code so the thumbnail script on
one domain cannot be used by another domain. The
list of allowed domains defaults to the current
domain but is configurable below as
$config_nohotlink_valid_domains. The message, text
size, colors and whether to blank the image or not
are also configurable
* Bugfix: URL image sources were not able to use the
non-GD GIF-reading functions
v1.2.2 - December 17, 2003
* Added option to use http:// URL as image source
v1.2.1 - December 11, 2003
* Added option to get source data from a database
rather than a physical file
* Bugfix: resize not proportional when wide image
limited more by max height than max width
Thanks mathias_strasserØgmx*net
* Removed caching code
v1.2.0 - December 10, 2003
* Added GIF support for versions of GD that do not
have built-in GIF support (v1.6.x) via the "GIF
Util" class by Fabien Ezber (www.yamasoft.com)
GD's built-in GIF-reading functions are faster, and
are present in PHP v4.3.0 or newer, but all versions
of GD can display resized GIF thumbnails now.
v1.1.2 - October 26, 2003
* check for source image existance to prevent text
error messages
* if GD not available, a GIF saying "no GD" is shown
instead of showing the original image
* Cache feature introduced
v1.1.1 - September 28, 2003
* better resize code by sfisher10Øcox*net
v1.1.0 - September 1, 2003
* initial public release
* thumbnails can now be larger than source image
* graphical error messages
v1.0.0 - January 7, 2002
* initial private release
