PHP and GD seem to have trouble creating images from PNGs of type greyscale with alpha when using imagecreatefrompng(). The results are incredibly distorted. I was wondering if anyone knew of a way to test for the colour type in order to notify the user of the incompatibility? Example: Original Image: http://dl.dropbox.com/u/246391/R...

Hi all fellow Wordpressers, I'm trying to apply GD star rating plugin to 4 specific pages. I know I can do it in the page editor, but I have about 30 pages so don't want to spend ages going through them all. Is there a way in the GD settings to default the plugin to not putting the block automatically on every page. Thanks for your hel...
I'm trying to create a GD image resource from a BMP image, however I'm having no luck. The BMP image in question was created and saved with Photoshop. I've tried a couple of BMPs I found on the web too, and they gave the same results. getimagesize() tells me the BMP image has an image type of IMAGETYPE_BMP (6) and a MIME type of 'image...

I have a problem with the GD functions. When I upload an image on localhost, everything works fine, and a thumbnail is created, but when I upload my website on hosting then imagecopyresized just fails. When I insert in a blank page, that function (whole resize function) it works just fine. What could be the problem? Update: Actually ...

Greetings. For a PHP-Project, I have to build PNG-images where I pass some text and then let imagick generate the image for that text. I did this kind of stuff with success in gd, but only had 1 font (per text-generation-block) to play with. As I want to change between 2+ fonts while generating this textblock I read a lot in Google, bu...
I'm using imagettftext to generate images from OpenType files. Everything works until I try to use an accented character (e.g. å) or a character such as √. In their place I get the .notdef glyph. The fonts I'm using definitely have these characters. To make things even more frustrating, when I use a TTF everything works as expected. An...

Currently I've got the following working just fine without any problems (yet). header ("Content-type: image/png"); $string = $_REQUEST['text']; $font = 15; $width = 300; $height = 350; $image = imagecreate($width, $height); $back = ImageColorAllocate($image, 255, 255, 255); $border = ImageColorAllocate($image, 0, 0, 0); ImageFilledR...
I'm looking at this code and have been through the docs but still don't understand how this should work. The code works fine just as it sits but I'm wondering if I should be outputting the header as png instead of jpeg. What exactly is going on in this code? Is the png image converted to jpeg? What I ultimately want to do is to waterma...

I'm trying to find the mime type of an image. PHP has the function getimagesize but that only takes a filename, whereas I have an image "resource" instead - i.e. an image created from imagecreatefromstring. I found the functions imagesx and imagesy which return the width/height from a resource but I can't find any function that tell me ...
