ID: 10097 User Update by: vha@oct31.de Old-Status: Feedback Status: Open Old-Bug Type: GD related Bug Type: *Graphics related Description: ImageColorAllocate() doesn't work with ImageCreateFromJPEG() explanation : The clocks hands SHOULD be in 2 different red variants if no different color is specified - it works in a low-color JPG : http://oct31.de/dyn/clock.php - no texture, image created with ImageCreate() - the clock hands show in red http://oct31.de/dyn/clock.php?img=ffffff&hs=30 - ffffff.jpg is a plain white JPG - the clock hands show in red The same on a JPG with more colors : http://oct31.de/dyn/clock.php?img=av_face1&hs=30 - av_face1 uses 2686 different colors - the clock hands show in a color that is used somewhere in the source JPG Previous Comments: --------------------------------------------------------------------------- [2001-04-01 13:19:02] sniper@php.net Could you please clarify this a little bit ie. add the examples of both cases (one color allocation that doesn't work and the one that works) --Jani --------------------------------------------------------------------------- [2001-04-01 13:15:24] vha@oct31.de After creating an image with ImageCreateFromJPEG() all ImageAllocate() on this image fail. The same script with ImageCreate() works fine. http://oct31.de/dyn/clock.php?img=avface2bl http://oct31.de/dyn/clock.php Config see http://oct31.de/php/phpinfo.php I don't run the server myself and cannot tell much about the configuration.

After trying ImageColorAllocate() on an image created from a JPG with only very few colors, the colors could be allocated --------------------------------------------------------------------------- [2001-04-01 13:04:39] sniper@php.net Please explain HOW it doesn't work? The URLs seem to work just fine. And you shouln't be reporting the bug if you're not admin of the site as you can't try any other versions of PHP or GD. And FYI: ImageColorAllocate() after imagecreatefromjpeg() works just fine for me. --Jani --------------------------------------------------------------------------- [2001-04-01 08:04:18] vha@oct31.de After creating an image with ImageCreateFromJPEG() all ImageAllocate() on this image fail.
