ID: 51671 Comment by: a dot schilder at gmx dot de Reported by: a dot schilder at gmx dot de Summary: imagefill does not work correctly for small images Status: Feedback Type: Bug Package: GD related Operating System: Windows XP SP3 PHP Version: 5.3.2 Assigned To: pajoye New Comment: I think you mean the doc of another function? The doc for "imagecreatetruecolor" says "This function will not work with GIF file formats." in the notes section (see: http://php.net/manual/en/function.imagecreatetruecolor.php). The note in the docs should be unrelated to this bug, because IMHO it doesn't make sense - but as I also mentioned, the problem disappeared after replacing "imagecreatetruecolor" with "imagecreate", so there seems to be a relation to the used function. Previous Comments: ------------------------------------------------------------------------ [2010-04-27 13:14:19] paj...@php.net Which part of the doc says that you can't create gif from true color images? As far as I remember the doc is about which buffer format is created when a script load a GIF image. imagecreatefromgif always returns a palette image. Also this question is unrelated to this problem. ------------------------------------------------------------------------ [2010-04-27 13:11:59] a dot schilder at gmx dot de I also tested it with imagecreate() instead of imagecreatetruecolor() and then it worked. Although it's said in the docs that imagecreatetruecolor() does not work with gif images, that's not true - it works in all cases, except in this example (see also bug #51414 for this doc problem). The code is taken from a class that creates an image and outputs it in different formats - so imagecreatetruecolor() has to be used, because the output format is not known on image creation. ------------------------------------------------------------------------ [2010-04-27 09:22:01] a dot schilder at gmx dot de Description: ------------ I try to use imagefill() with an image that has a width of one pixel, but it does not work. For larger image it works as expected. Test script: --------------- // image 1 $image = imagecreatetruecolor(50, 50); $white = imagecolorallocate($image, 255, 255, 255); imagefill($image, 0, 0, $white); imagegif($image, __DIR__ . '/50x50.gif'); // image 2 $image = imagecreatetruecolor(1, 50); $white = imagecolorallocate($image, 255, 255, 255); imagefill($image, 0, 0, $white); imagegif($image, __DIR__ . '/1x50.gif'); Expected result: ---------------- 1) White image, 50x50 pixel. 2) White image, 1x50 pixel. Actual result: -------------- 1) White image, 50x50 pixel. 2) Image, 1x50 pixel, with the first two pixels (0/0, 1/0) in white, the rest in the default color (black). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51671&edit=1
