ImageFillToBorder seems to act strangely (no output) when using alpha channel (?) on color and / or bordercolor values, on an alphablending image. Configuration: ************** winxp apache 2.0.48 php 4.3.4 / 4.3.5RC3 gd2 module loaded Reproduce code: --------------- <?php $im = ImageCreateTrueColor(10, 10); imagealphablending($im, true); imagesavealpha($im, false); $bordercolor=ImageColorAllocateAlpha($im, 0, 0, 0, 2); $color = ImageColorAllocateAlpha($im, 0, 0, 0, 1); ImageFillToBorder($im, 5, 5, $bordercolor, $color); ?> Expected result: ---------------- Do work as supposed to, or output some error. Actual result: -------------- Actual result: ************** Browser hangs and output an alert "Document contains no data". I'm not experienced enough to give you more debug details... but it obviously break something... Additionnal comment: ************** The values that trigger the bug seems to be pretty much random. You can reproduce the problem with: $bordercolor=ImageColorAllocateAlpha($im, 0, 254, 0, 0); $color = ImageColorAllocateAlpha($im, 0, 255, 255, 75); Or even reproduce it with: $bordercolor=ImageColorAllocate($im, 0, 254, 0); $color = ImageColorAllocateAlpha($im, 0, 255, 255, 75); (wich is much more logical on an alphablending image...) But odly it works ok with: $bordercolor=ImageColorAllocateAlpha($im, 0, 0, 0, 0); $color = ImageColorAllocateAlpha($im, 0, 255, 255, 75); I can't find any coherence in the problematic values, except that they involve alpha channel. If this is a doc problem, or if I missed something, please forgive this report... Anyway, long life to php.
