Title: Thumbnail background colors
Post by: Steel Rat on September 05, 2005, 12:08:47 AM

Hello All,

Been running 4Images for a few days now, added a few mods, things are smooth, life is good.

one question I have not been able to find the answer to, however, is how to change the background colors for thumbnails created by GD. The vast majority of the images I deal with are transparent PNGs, and GD places a black background on all of them. I would prefer a grey or white background so the image detail isn't lost on darker images. Anyone have any quick tips on how to do this?

Thanks in advance!

At the moment I dont have possibility to test it, so, it might take a few trys before we figure something out.
Try this first:
in includes/image_utils.php find:

Code: [Select]

    $thumb = imagecreatetruecolor($width, $height);Insert _below:

Code: [Select]

    imagealphablending($thumb, false);
Please note, in order this to work, you must have GD v2.0.1 or later, with previous versions you will see any changes at all.
