when a color is defined as transparent, anytime that color is used in another function (before or after transparency definition) will be transparent ex: $red = ImageColorAllocate ($im, 233, 14, 91); $blue = ImageColorAllocate ($im, 0x20, 0x60, 0xaa); imagefilledarc ($im, 100, 100, 80, 80, 0, 60, $blue, IMG_ARC_PIE);//arc is transparent even though is not defined yet $trans=imagecolortransparent($im,$blue);//affects all occurances of blue, before and after this line ALSO: ImageString ($im, 10, 5, 5, "Transparent Text String", $blue); ---is equivalent to---- ImageString ($im, 10, 5, 5, "Transparent Text String", $trans); -- http://www.php.net/manual/en/function.imagecolortransparent.php http://master.php.net/manage/user-notes.php?action=edit+17399 http://master.php.net/manage/user-notes.php?action=delete+17399 http://master.php.net/manage/user-notes.php?action=reject+17399
