I read the documentation and found that the create function receives an array with options, where i could pass the parameter 'preserveTransparency' and 'preserveAlpha'. The problem is that when the format of the image is STRING (as set when you create an image from a stream) this options does not works. I found this line (line 1154) in GDThumb.inc.php: <code>if ($this->format == 'PNG' && $this->options['preserveAlpha'] === true)</code> I found that if i change that line, the transparency is now preserved: <code>if ($this->format == 'PNG' || $this->options['preserveAlpha'] === true)</code> adamquadmon on "PHP Version 5.3.0 Issues" http://phpthumb.gxdlabs.com/forums/topic/php-version-530-issues#post-113 Mon, 28 Sep 2009 09:47:18 +0000 adamquadmon 113@http://phpthumb.gxdlabs.com/forums/ for this error: <code> PHP Warning: Parameter 6 to GdReflectionLib::createReflection() expected to be a reference, value given in ThumbBase.inc.php on line 197 </code> - go on that line (197) - look at the previous one (196) change it from: <code> $args[] = $this; </code> to: <code> $args[] = &$this; </code> Danielpk on "Suggest a fix." http://phpthumb.gxdlabs.com/forums/topic/suggest-a-fix#post-112 Thu, 24 Sep 2009 16:53:58 +0000 Danielpk 112@http://phpthumb.gxdlabs.com/forums/ Well, i using this with CakePHP and i got this NOTICE: <blockquote>Notice (8): Undefined index: JPG Support [APP\vendors\phpThumb\GdThumb.inc.php, line 1080] </blockquote> So for fix it i did: <code>case 'JPG': $isCompatible = (isset($gdInfo['JPG Support'])) ? $gdInfo['JPG Support'] : $gdInfo['JPEG Support']; break; case 'PNG': $isCompatible = $gdInfo['PNG Support']; break;</code> The problem was that gdInfo dont had JPG Support index.

PHP 5.3.x will have JPEG instead of JPG. I tried PHP 5.2.8 which is on most of my clients' hosting servers and got JPG from gd_info. Now the problem is solved. If you have a server or have installed the server with PHP 5.3.x, you may need to change the GD Thumb Class Definition File Class in order to make the PHP Thumb function properly. dingwen on "GD 2.0.34+ Compatibility Issue" http://phpthumb.gxdlabs.com/forums/topic/gd-2034-compatibility-issue#post-53 Wed, 15 Jul 2009 23:08:38 +0000 dingwen 53@http://phpthumb.gxdlabs.com/forums/ After some research, I found that my couple clients hosting server are have GD 2.0.34, but they have JPG instead of JPEG. This may be the OS dependence issue. If anyone has a windows OS hosting server, please use the following code to dump the GD info and see it is JPG or JPEG. <code><?php $tmp = gd_info(); echo '<table>'; foreach($tmp as $key=>$value) { echo '<tr>'; echo '<td>' . $key . '</td>'; echo '<td>' . $value . '</td>'; echo '</tr>'; } echo '</table>'; ?></code> The "JPEG Support" might only happen in Windows Vista. dingwen on "GD 2.0.34+ Compatibility Issue" http://phpthumb.gxdlabs.com/forums/topic/gd-2034-compatibility-issue#post-52 Wed, 15 Jul 2009 14:23:46 +0000 dingwen 52@http://phpthumb.gxdlabs.com/forums/ Hi everyone, I start using PHP Thumb just couple weeks ago. Thanks for a such great utility component. After I have upgraged my WAMP to the newest version, I realized GD library in the WAMP has changed to 2.0.34. The GD version change results that GD Thumb Class Definition File Class will not be able to verify the JPEG mime type and store into format variable. Thus, the image processes are triggering errors. Below is the gd_info dump. <code>GD Version : bundled (2.0.34 compatible) FreeType Support : 1 FreeType Linkage : with freetype T1Lib Support : GIF Read Support : 1 GIF Create Support : 1 JPEG Support : 1 PNG Support : 1 WBMP Support : 1 XPM Support : XBM Support : 1 JIS-mapped Japanese Font Support : </code> I put a quick fix for my code since the deadline is approching. I changed all the JPG to JPEG in GDThumb.inc.php. However, this fix is totally depending on the GD version on the server. If your PHP Thumb is running fine, you don't need to change it. atDev on "Pixelated corrupt image output" http://phpthumb.gxdlabs.com/forums/topic/pixelated-corrupt-image-output#post-41 Thu, 02 Jul 2009 05:01:16 +0000 atDev 41@http://phpthumb.gxdlabs.com/forums/ Ignore this, my fault my setting of the quality was bad so it was assuming "0" quality. atDev on "Pixelated corrupt image output" http://phpthumb.gxdlabs.com/forums/topic/pixelated-corrupt-image-output#post-40 Thu, 02 Jul 2009 04:56:38 +0000 atDev 40@http://phpthumb.gxdlabs.com/forums/ It seems to be happening for any image I try. atDev on "Pixelated corrupt image output" http://phpthumb.gxdlabs.com/forums/topic/pixelated-corrupt-image-output#post-39 Thu, 02 Jul 2009 04:52:23 +0000 atDev 39@http://phpthumb.gxdlabs.com/forums/ Perhaps I am missing something but I am resizing this image (the small one): <a href="http://images.google.com/imgres?imgurl=http://people.mozilla.com/~faaborg/files/20061210-newCar/newCar.jpg_large.jpg&imgrefurl=http://blog.mozilla.com/faaborg/2006/12/10/my-new-scion-xa/&usg=__WKiKcmdQE-X2Ow8NiZI8MB_l_80=&h=2304&w=3072&sz=1949&hl=en&start=4&um=1&tbnid=VSSWewRRZnOgfM:&tbnh=113&tbnw=150&prev=/images%3Fq%3Dcar%26hl%3Den%26client%3Dfirefox-a%26rls%3Dorg.mozilla:en-US:official%26sa%3DG%26um%3D1">Google image of a car</a> But it comes out half grayscale and extremely pixelated.

Ian on "Remote Images - Fatal Error" http://phpthumb.gxdlabs.com/forums/topic/remote-images-fatal-error#post-32 Thu, 25 Jun 2009 21:51:48 +0000 Ian 32@http://phpthumb.gxdlabs.com/forums/ Well, you could catch the exception ;) Basically the library can't open the file (hence the "Image file not found" error), so it throws an exception. As to the remote image portion of your question, I've never tried it myself, but typically with remote files, you'd need to make sure "allow_url_fopen" is enabled in your php.ini file. But, the class wouldn't really deal with it properly still. I could probably get something whipped up in the near future... can you file an enhancement request over at <a href="http://trac.gxdlabs.com/projects/phpthumb/newticket" rel="nofollow">http://trac.gxdlabs.com/projects/phpthumb/newticket</a> zactanaz on "Remote Images - Fatal Error" http://phpthumb.gxdlabs.com/forums/topic/remote-images-fatal-error#post-31 Thu, 25 Jun 2009 19:57:51 +0000 zactanaz 31@http://phpthumb.gxdlabs.com/forums/ This is a amazing library, easy and simple to use. I found out the when you point to a remote image to generate a thumb is gives a Fatal Error. Here it is: <code> Fatal error: Uncaught exception 'Exception' with message 'Image file not found: <a href="http://www.sample.com/sub-dir/image.jpg" rel="nofollow">http://www.sample.com/sub-dir/image.jpg</a>' in C:\xampplite\htdocs\includes\ThumbBase.inc.php:165 Stack trace: #0 C:\xampplite\htdocs\includes\ThumbBase.inc.php(144): ThumbBase->triggerError('Image file not ...') #1 C:\xampplite\htdocs\includes\ThumbBase.inc.php(93): ThumbBase->fileExistsAndReadable() #2 C:\xampplite\htdocs\includes\GdThumb.inc.php(96): ThumbBase->__construct('http://www.sampl...') #3 C:\xampplite\htdocs\includes\ThumbLib.inc.php(127): GdThumb->__construct('http://www.sampl...', Array) #4 C:\xampplite\htdocs\twistys\images.php(14): PhpThumbFactory::create('http://www.sampl...') #5 {main} thrown in C:\xampplite\htdocs\includes\ThumbBase.inc.php on line 165 </code> Is there a workaround this problem?
