hello all,
i have a function to copy a png 24 while preserving transparency and recolor the image and save a new file. the color works but the image edges become fuzzy. i'm not entirely sure what is causing this. i'd like to have the same quality as the original image with clean edges. love to hear suggestions. thanks a lot
PHP Code:
<?php function color_png($src_string, $directory, $r, $g, $b){
$im = imagecreatefrompng($src_string);
imageantialias($im, true);
$width = imagesx($im);
$height = imagesy($im);
$imn = imagecreatetruecolor($width, $height);
imagealphablending($imn,false);
$col=imagecolorallocatealpha($imn,255,255,255,127);
imagesavealpha($imn,true);
imagefilledrectangle($imn,0,0,$width,$height,$col);
imagealphablending($imn,true);
imagecopy($imn, $im, 0, 0, 0, 0, $width, $height);
imagefilter($imn, IMG_FILTER_NEGATE);
imagefilter($imn, IMG_FILTER_COLORIZE, $r, $g, $b);
imagepng($imn, $directory);
imagedestroy($imn);
}
?>
