Tsukiyomi Posted October 17, 2006 Share Posted October 17, 2006 I've been using the following script to create thumbnails[code]$image = "$d/images/avatar.jpg";$start_image = "avatar.jpg";$savelocation = "$d/images/";if(!file_exists("$path_to_images")) { $oldumask = umask(0); mkdir("$path_to_thumbnail_dir", 0777); umask($oldumask);}if (!$max_width) $max_width = 125;if (!$max_height) $max_height = 125;$size = GetImageSize($image);$width = $size[0];$height = $size[1];$x_ratio = $max_width / $width;$y_ratio = $max_height / $height;if (($width <= $max_width) && ($height <= $max_height)) { $tn_width = $width; $tn_height = $height;} else if (($x_ratio * $height) < $max_height) { $tn_height = ceil($x_ratio * $height); $tn_width = $max_width;} else { $tn_width = ceil($y_ratio * $width); $tn_height = $max_height;}$src = ImageCreateFromJpeg($image);$dst = ImageCreate($tn_width,$tn_height);ImageCopyResized($dst, $src, 0, 0, 0, 0, $tn_width,$tn_height,$width,$height);ImageJpeg($dst,"$savelocation"."thumb_$start_image");//the above line is what creates the actual thumbnail jpegImageDestroy($src);ImageDestroy($dst);[/code]It works fine, the image is created at the proper size with the aspect ratio preserved, the only problem is I'm losing a lot of color quality. Can someone please explain to me why this is?Here are the two images:Original:[img]http://img.photobucket.com/albums/v143/GammaBeast/avatar.jpg[/img]New:[img]http://img.photobucket.com/albums/v143/GammaBeast/thumb_avatar.jpg[/img]Thanks.
