[RESOLVED] Hi! Need Help with PHP Image Editing...

Hi guys,

I'm trying to write ontop of a transparant gif -- and keep the transparancy.

I can actually do it really easy, but i cannot get the text to change colour.

My code is basicly this:

$im = imagecreatefromgif ("back.gif");

$back_ground = imagecolorallocate ($im, 207, 207, 207);
$white = imagecolorallocate ($im, 255, 255, 255);
$black = imagecolorallocate ($im, 0, 0, 0);

imagettftext($im, 14, 0, 45, 67, $white, "arial.ttf", "Hello");


imagegif ($im,"preview.gif");

imagedestroy ($im);

The font file is in the right place, but nothing i can do will let me change the colour of the word "Hello".

If i do the same with a gif that does not have a transparant background, it works ok.

Is it somthing to do with the settings when exporting a gif with adobe photoshop?

Any help on doing this would be amazing!

Cheers all.

Hmm... I just copied your script (and whipped up a simple GIF in Ulead PhotoImact 12) and it worked fine... change $white's color values to 128/128/128 (grey) and the font changed as well.

If you upload the image files, I can always test with what you're using, but other than that... I don't know what to say. When you run the code snippet in your last post, is the text white? What do you change the code to and what does the text look like?

Thanks very much mate!

I actually just found another way if anyone else ever gets this problem!

My gif had used all its 256 colours up -- and the REAL values i've been trying to use, were not in the colours (i.e there is no true black or white)

So i used the function imagecolorclosest($im,255,255,255);

--- Which works soo close, i cannot see any differnce.

Cheers again bradgrafelman for your help 🙂
