RE: Bug #12963 Updated: ImageColorAllocate() doesn't work with PNGs

Hi, ImageColorResolve() doesn't solve it - but you will be happy to know that I did solve it - form your palette tip. Guessing that the color is not in the palette, use: imagecolorset($image,1,255,100,100); to force your color into the palette. So, this works: ********************************* <?php header ("Content-type: image/png"); $text=implode($argv," "); $image=imageCreateFromPNG("basic.png"); imagecolorset($image,1,255,100,100); $text_color=imageColorAllocate($image,255,100,100); $textX=(imageSX($image)-imageFontWidth(4)*strlen($text))/2; imageString($image,5,$textX,10,$text,$text_color); imagePNG($image); imageDestroy($image); ?> ********************************* Thanks for the help. P.S. I spotted a couple of spelling mistakes in the PHP manual. In cpdf_save and cpdf_restore, you write 'enviroment'. The correct spelling is 'environment'. (Mind you - this is English, not American').

This works for JPEG, but the quality suffers, and my build of PHP doesn't support GIF's. ------------------------------------------------------------------------ ATTENTION!
