Not sure about which libttf version. I know I have freetype-2.0.9
installed on the machine with the link below. Not sure if that helps.

The code that produces bad results:
<?php
$text = "Jagged Text";
Header("Content-type: image/png");
$source_file = "bluebox.jpg";
$target_id = ImageCreateFromJPEG ($source_file);
$fontsize = 36;
$xpos = 20;
$ypos = 40;
$font_color = ImageColorAllocate ($target_id, 255, 255, 255);
$font = "/usr/local/www/archer/FRAMDCN.TTF";
ImageTTFText ($target_id, $fontsize, 0, $xpos, $ypos, $font_color,
$font, $text);
ImageJpeg($target_id);
ImageDestroy($target_id);
?>
The code that produces good results (trial and error figured this one
out):
<?
$text = "Clear Text";
header("Content-type: image/png");
$source_file = "bluebox.jpg";
$source_size = getimagesize($source_file);
$source_w = $source_size[0];
$source_h = $source_size[1];
$source_id = ImageCreateFromJPEG($source_file);
$target_id = ImageCreate ($source_w, $source_h);
ImageCopyResampled($target_id, $source_id, 0, 0, 0, 0, $source_w,
$source_h, $source_w, $source_h);
$fontsize = 36;
$xpos = 20;
$ypos = 40;
$font_color = ImageColorAllocate ($target_id, 255, 255, 255);
$font = "/usr/local/www/archer/FRAMDCN.TTF";
ImageTTFText ($target_id, $fontsize, 0, $xpos, $ypos, $font_color,
$font, $text);
ImagePNG ($target_id);
ImageDestroy ($target_id);
?>

I've tried to duplicate the problem you've described using PHP 4.3.0
using bundled GD and PHP 4.2.3 using standard GD. Both produce
absolutely identical images with the TTF (arial) font that I've used.
What version of freetype library are you using and if possible can you
put the 'good' & 'bad' image online for comparison reasons.

They are equal. Basically, this code takes a template image, and places
some dynamic text on top of it. It's used to make custom header
graphics for a site, without the need to create new images in
Photoshop, etc.

Are the dimentions of the 'source' image greater, less then or equal to
the size of the 'destination' image?

I assume the bundled library. Although the unbundled library did exist
on this machine before I compiled the new PHP. And it was version
2.0.1.

Are you using bundled or non-bundled GD library? In case of the latter,
what version of GD library are you using?
