Any ideas as to how I can fix this function??? -----Original Message----- From: Edward Peloke [mailto:epeloke@echoman.com] Sent: Thursday, June 03, 2004 4:18 PM To: Php-General Subject: [PHP] image resize looks horrible.. I am using the below function which does seem to resize the image yet the colors in the resized image look horrible. How can I resize the image yet keep the colors in tact? Thanks, Eddie Justin-I tried your code but it didn't seem to do anything...I will just use this function if the color will work. function createthumb($name,$filename,$new_w,$new_h){

        global $gd2;
        $system=explode(".",$name);
        $src_img=imagecreatefromjpeg($name);
        $old_x=imageSX($src_img);
        $old_y=imageSY($src_img);
        if ($old_x > $old_y) {
                $thumb_w=$new_w;
                $thumb_h=$old_y*($new_h/$old_x);
        }
        if ($old_x < $old_y) {
                $thumb_w=$old_x*($new_w/$old_y);
                $thumb_h=$new_h;
        }
        if ($old_x == $old_y) {
                $thumb_w=$new_w;
                $thumb_h=$new_h;
        }
        if ($gd2==""){
                        $dst_img=ImageCreate($thumb_w,$thumb_h);

imagecopyresized($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y);

        }else{
                $dst_img=ImageCreateTrueColor($thumb_w,$thumb_h);

imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y );

        }
        if (preg_match("/png/",$system[1])){
                imagepng($dst_img,$filename);
        } else {
                imagejpeg($dst_img,$filename);
        }
        imagedestroy($dst_img);
        imagedestroy($src_img);

}
