image manipulation...

stevesweetland

why doesnt this code

$textcolor = "#FFFFFF";
imagettftext ($dst_thumb, 8, 0, 2, $dest_height-4, $textcolor, "/home/sites/home/web/steve/core/barmeno.ttf", "www.ess-thing.com");

put WHITE text onto the image? im doing lots of code around this, and it works, but it seems i cant change the color of the text!

Try allocating the white color like this instead, and see if that does any better for you...

$textcolor = imagecolorallocate($dst_thumb, 255,255,255);
imagettftext ($dst_thumb, 8, 0, 2, $dest_height-4, $textcolor, "/home/sites/home/web/steve/core/barmeno.ttf", "www.ess-thing.com");

just the ticket mate, cheers.

any idea how i might desaturate an image also? (ie, modify it to be grayscale....)

stevesweetland

no?

Sorry, I was out for a bit... I don't know off the top of my head, but could dig into the manual a bit... I will get back with you later on. (In the mean time, hopefully one of the others might have a chance to lend a hand.)

...imagecopymergegray()

You could also use [man]imagecolorallocatealpha()[/man] instead of imagecolorallocate, which will allow you to set an opacity value between 0 and 127. It wouldn't be grayscale, but instead it would be more washed out colors.
