Returns a color the same as - or as close as possible to - the specified color. Unlike imagecolorexact() , but similar to imagecolorclosest() , this function always returns a color, even if the color returned is not at all similar to the RGB values specified. The function will move through the color palette of the image until it finds a close match, which may not be close at all.
Example 399. Determine the closest color
header("Content-type: image/png"); $im = imagecreate(200, 200); $red = imagecolorallocate($im, 255, 0, 0); $offblue = imagecolorallocate($im, 90, 90, 200); imagefill($im, 0, 0, $red); imagefilledrectangle($im, 10, 10, 40, 40, $offblue); // get a close color and new box $newblue = imagecolorresolve($im, 0, 0, 255); imagefilledrectangle($im, 100, 100, 140, 140, $newblue); imagepng($im); imagedestroy($im);
