note 21922 added to function.imagesetpixel

The example above diden't work, because of some errors. This should work and it's also faster because there is only one 512*512 loop. (but it is still very slow) <? $filename="lena.raw"; $width=512; $height=512; $fp=fopen($filename, "r"); $contents=fread($fp,filesize($filename)); fclose($fp); $image=imagecreate($width,$height); // create greyscale palette because the image is limited to 256 colors for ($i=0;$i<256;$i++){ ImageColorAllocate($image,$i,$i,$i);} // This is slow, but probably the only way for ($i=0;$i<512;$i++){ for ($j=0;$j<512;$j++){ imagesetpixel ($image,$i,$j,ord($contents[$i+$j*512])); } } imagepng($image,"result.png"); imagedestroy($image); echo "<img src=result.png></img>"; ?> -- Dino Patti -- http://www.php.net/manual/en/function.imagesetpixel.php http://master.php.net/manage/user-notes.php?action=edit+21922 http://master.php.net/manage/user-notes.php?action=delete+21922 http://master.php.net/manage/user-notes.php?action=reject+21922
