Hi to all

We have a script that create a "button" image with gd
This script use our ttf upload online, in script dir

All work great ok for 1 year, now the image created is bad.
Seems they have antialiasing but this is set 0

Script is really simple:

//================================================
$im = ImageCreateFromGif('base.gif');
$color = ImageColorAllocate($im,255,255,255);
imagettftext($im, 8.5, 0, 14, 13, -$color, "asimo.ttf", $_POST['name']);
$file_pulsante="$dirsharefile/".$pulsante.".gif";
Imagegif($im,$file_pulsante);
ImageDestroy($im);
//================================================

Thks

What is "bad" about the generated image? More details on the failure will help others to provide accurate assistance.

If it's difficult to explain problem, it will be difficult for anyone to suggest a fix. :) Give it a try, any information is helpful.

Thanks for the sticky. I agree that is hard to describe.

ssuming that the font file hasn't changed, the handling of anti-aliasing has changed. The image is still generated, but the inside corners of text have an extra pixel filled in.

Try changing a few settings to see how that effects your output:

First, toggle the negative color value (which determines if GD uses antialiasing):

imagettftext($im, 8.5, 0, 14, 13, $color, "asimo.ttf", $_POST['name']); 

Next, switch to a different font size. Specifically an integer rather than a float:

imagettftext($im, 8, 0, 14, 13, -$color, "asimo.ttf", $_POST['name']); 

Finally, confirm your font file is the correct one. Upload a new file (get it from the source, not a backup) and call that one instead.

imagettftext($im, 8, 0, 14, 13, -$color, "asimo2.ttf", $_POST['name']); 

I realize these are more troubleshooting tips than a solution, but at least it gets you going in the right direction. I've not experienced this particular problem, so I can't provide better info.

I'm afraid the issue is probably related to a change at your host/server configuration. Do you know if they have updated/changed the GD or PHP version(s) lately?

[webstyler]

yes, off course

gd is =

php is newer version, but config seems =

:/
