On some slower servers the caching is a really nice feature to have. Am I not using the software correctly, or is it actually missing from version 3? If it's missing, are there any plans to introduce it? Whilst leaving this message, I'd like to say what a great bit of software I think php Thumb is.

I'm doing this for a couple of reasons: <ul><li>Spam - The current issue tracker (trac) gets a TON of spam. This sucks. Since GitHub has integrated issue tracking, I can now use that!</li><li>Wiki - It's got an integrated wiki, which anyone can help keep up to date or expand on. Collaboration is fun!</li><li>Git - Git's awesome... GitHub makes it easier for other people to work on the code and contribute as well. I think it's a better system all-around, especially for open-source projects</li> </ul> I'll be updating various links and stuff as the migration progresses, but for now you can visit the new project at: <a href="http://github.com/masterexploder/PHPThumb" rel="nofollow">http://github.com/masterexploder/PHPThumb</a> skyzyx on "Feature Request: Memory-only images" http://phpthumb.gxdlabs.com/forums/topic/feature-request-memory-only-images#post-125 Fri, 16 Oct 2009 23:23:36 +0000 skyzyx 125@http://phpthumb.gxdlabs.com/forums/ I'm probably a special case in that I'm doing some nutty things with Amazon S3, but I'd like to be able to use an S3 class to fetch the binary image data, pass that into PHPThumb, and (besides show and save) add a third option for returning the processed binary image data to a variable that I can use to write back to S3. Basically, I'd like the entire resizing/converting process to happen in memory, so that I can pull from (and push to) S3 without having to create temporary files on disk or be forced to output them to the buffer. Within a few minutes I was able to write a plugin that did the memory output, but I don't seem to be able to pass image data in without hacking on the core library — and that's not something I want to have to do.

I'm sorta guessing that most browsers can handle jpgs & gifs - w3c has this to say on the matter.... <blockquote>Attributes of this type identify the allowable content type(s) of an associated URI (usually a value of another attribute on the same element). At its most general, it is a comma-separated list of media ranges with optional accept parameters, as defined in section 14.1 of [RFC2616] as the field value of the accept request header. In its simplest case, this is just a media type, such as "image/png" or "application/xml", but it may also contain asterisks, such as "image/*" or "*/*", or lists of acceptable media types, such as "image/png, image/gif, image/jpeg". The user agent must combine this list with its own list of acceptable media types by taking the intersection, and then use the resulting list as the field value of the accept request header when requesting the resource using HTTP. For instance, if the attribute specifies the value "image/png, image/gif, image/jpeg", but the user agent does not accept images of type "image/gif" then the resultant accept header would contain "image/png, image/jpeg". A user agent must imitate similar behavior when using other methods than HTTP. For instance, when accessing files in a local filestore, might cause the user agent first to look for a file logo.png, and then for logo.jpg. If a value for the content type is not given, "*/*" must be used for its value. For the current list of registered content types, please consult [MIMETYPES].</blockquote> So, placing a <code>In its simplest case, this is just a media type, such as "image/png" or "application/xml", but it may also contain asterisks, such as "image/*" or "*/*", or lists of acceptable media types, such as "image/png, image/gif, image/jpeg". </code> type statement would keep me in alignment with the rules - My question then is, what would be, if any, the effect of removing the code from your library with those directives in ? -- Yeah, I know I'm a pain in the ass, but, please try to see it my way - I already have a header section to look after all my pages, and I would be most pleased to be able to adapt to use your fantastic php-code.

I have a special field for image classes, so i want to resize them with <a href="http://www.site.com/show_imagex.php?file=%field%" rel="nofollow">http://www.site.com/show_imagex.php?file=%field%</a> this works in my code but i have lots of images, around 20+ per page, so i think it takes a hit on the server. So i was thinking to save them and display them, something like this: <code><?php require_once 'ThumbLib.inc.php'; $fileName = (isset($_GET['file'])) ? urldecode($_GET['file']) : null; if ($fileName === null || !file_exists($fileName)) { echo "imagine lipsa"; } try { $thumb = PhpThumbFactory::create($fileName); } catch (Exception $e) { echo "exception"; } if(!file_exists('static/'.$fileName)) { $thumb->adaptiveResize(170, 80); $thumb->save('static/'.$fileName); } $new = PhpThumbFactory::create('static/'.$fileName); if(file_exists('static/'.$fileName)) { $new->show(); } ?></code> So basically get the field name, save in static, and show it. Now i dont know if this uses resources each time i call it, to create a new thumb, or it takes it from static.

Whenever you create a new release, stick it in a versioned sub-folder of the "tags" or "releases" directories (e.g. /svn/tags/3.0.53). It would appear that the current version of the software exists only in the trunk, sticking me in the unfavorable position of having to worry about broken builds if I <code>svn up</code> my svn:externals. Any chance of releases being organized this way? tronics on "preserve transparency in png and gif" http://phpthumb.gxdlabs.com/forums/topic/preserve-transparency-in-png-and-gif#post-85 Sun, 16 Aug 2009 14:59:44 +0000 tronics 85@http://phpthumb.gxdlabs.com/forums/ Hello! Everything works very well so far, but I found problems with transparency. $_filename="nicename.png"; $format="png"; $thumb->resize($width,$height')->save($_filename,$format); $thumb = PhpThumbFactory::create($_filename);//take the cached Thumb. $thumb->show(); When I tried to resize and save this image here with png and transparency it turns out to have a black background (the same as when saved in jpg Format) Try this image to test it: <a href="http://www.atomikframework.com/assets/images/logo.png" rel="nofollow">http://www.atomikframework.com/assets/images/logo.png</a> Do I make any mistake, or is this a bug?

Sorry if my english is not very good. :) I'm a spanish web developer. I love your thumb tool, a great piece of software! but i need 2 little modifications to make it perfect for me. First... i want resize my thumb with only the "WIDTH" value or only the "HEIGHT" value. For example in a 800x600 picture, i resize the height to 100 (height = 100 and width = 133) and then crop in X=0 and Y=0 to 100x100 thumbnail. And finally... a parameter to apply a "Unsharp Mask" to the thumbmails (you can take the code here <a href="http://vikjavev.no/computing/ump.php" rel="nofollow">http://vikjavev.no/computing/ump.php</a>).

My goal is to keep the orginal size images and just watermark them, while also creating thumbnails of them. The problem is when I'm trying to watermark them and save them, php throws an warning. Here is my code for the plugin: <code> class GdWatermarkLib { /** * Instance of GdThumb passed to this class * * @var GdThumb */ protected $parentInstance; protected $currentDimensions; protected $workingImage; protected $newImage; protected $options; public function createWatermark ($watermark, &$that) { // bring stuff from the parent class into this class... $this->parentInstance = $that; $this->currentDimensions = $this->parentInstance->getCurrentDimensions(); $this->workingImage = $this->parentInstance->getWorkingImage(); $width = $this->currentDimensions['width']; $height = $this->currentDimensions['height']; $watermarksize = getimagesize($watermark); $dest_x = $width - $watermarksize[0] - 5; $dest_y = $height - $watermarksize[1] - 5; $watermark = imagecreatefromjpeg($watermark); imagecopymerge($this->workingImage, $watermark, $dest_x, $dest_y, 0, 0, $watermarksize[0], $watermarksize[1], 100); return $that; } } $pt = PhpThumb::getInstance(); $pt->registerPlugin('GdWatermarkLib', 'gd'); </code> Here are my lines of code to call it. <code> require_once 'functions/ThumbLib.inc.php'; $thumb = PhpThumbFactory::create('test.jpg'); $thumb->createWatermark('watermark.jpg')->save('watermarked_image.jpg'); </code> The code above just takes the image, applies the watermark and saves it. When I run the code above I get <blockquote>Warning: imagecopymerge(): supplied argument is not a valid Image resource in C:\AppServ\www\imagetest\thumb_plugins\gd_watermark.inc.php on line 64</blockquote> However, if I try to resize it before applying the watermark, it works fine. See code below. <code> require_once 'functions/ThumbLib.inc.php'; $thumb = PhpThumbFactory::create('test.jpg'); $thumb->resize(600, 600)->createWatermark('watermark.jpg')->save('watermarked_image.jpg'); </code> Environment: Windows XP Apache 2 PHP Version 5.2.1 GD Version 2.0.28 Do you have any ideas what might be causing that?

I have refreshed my browser, even done "view image" to isolate it from the page and refreshed (which usually works in Firefox) but it's still the original. Only when I delete the folders inside of phpThumb/cache/ do the new versions show up. The configuration options seem to suggest that they should be re-caching if the original has changed. The cache settings for phpThumb.config.php are: // * Cache directory configuration (choose only one of these - leave the other lines commented-out): // Note: this directory must be writable (usually chmod 777 is neccesary) for caching to work. // If the directory is not writable no error will be generated but caching will be disabled. $PHPTHUMB_CONFIG['cache_directory'] = dirname(__FILE__).'/cache/'; // set the cache directory relative to the phpThumb() installation //$PHPTHUMB_CONFIG['cache_directory'] = $PHPTHUMB_CONFIG['document_root'].'/phpthumb/cache/'; // set the cache directory to an absolute directory for all source images //$PHPTHUMB_CONFIG['cache_directory'] = './cache/'; // set the cache directory relative to the source image - must start with '.'
