Don't show the text also with the latest CVS version.

Hello,

Can you provide a small script to reproduce your problem, this function works like a charm here.
This line:
$tc  = ImageColorAllocate ($im, $colors[$color][0],
$colors[$color][1], $colors[$color][2]);
can be your problem. Check the $color array, or set error_reporting(E_ALL); to see if they are initialized correctly (btw, use always this flag to develop).

Second point, ImageAlphaBlending is useless in your case, ImageColorAllocate allocates a color with an opaque alpha channel.

thank's for your interest,

pierre

This is the original script modified only for running without external parameters. You can download the image bottone1.png by the url http://www.i-dome.com/microtools/bottoni/bottone01.png and the font BOOMBOX.TTF by url http://www.i-dome.com/microtools/fonts/BOOMBOX.TTF
The program must run with this parameters:
testo=the text
larghezza=the width (default 96 pix)

The program run correctly on version 4.2.3 of PHP with gd2.0.4. Also it runs correctly when I give the parameter "larghezza" (with) at the original image width (96).
Thank you very much

Paolo Morandi
