Status: Bogus
Bug Type: GD related
Operating System: RedHat 7.3
PHP Version: 4CVS-2003-10-20 (stable)
New Comment:
Ok, I think I found the problem and a fix !
In fact the problem occurs on my RedHat box but not on my Debian box.
I've managed to find that :
freetype-config --version
is 9.4.3 on RedHat and 9.5.3 on Debian ! I tried to uninstall
libfreetype6 on Debian, and install the 9.4.3, and the problem then
occurs ! So I think it must be the libfreetype6 that must be updated,
but I don't know exactly how... Because the 9.5.3 is not stable (my
Debian install is unstable/testing, so...).
I'll try to install 9.5.3 on RedHat, and feedback if OK or not. Please
note that this bug is the same as #7769 (not sure), #21879, #21554
(already closed) and #15405. Many to close then if I found that's the
good workaround ;o)

Description:
------------
My server is :
- RedHat 7.3
- Apache 1.3.28
- PHP 4.3.4RC3-dev (tried this last one to see if the bug disappears,
but not)
- bundled GD (2.0.15)
- FreeType 2.1.5
The problem is that when I use a negative color index for
ImageTTFText(), the antialias disappears, but the text is quite ugly,
and should not. No info on GD/FreeType website is available on such a
bug.
Reproduce code:
---------------
$height = 60;
$width = 150;
$font = "arial.ttf";
$img_en = imageCreate($width, $height);
$background_en = imageColorAllocate($img_en, 0xFF, 0xFF, 0xFF);
$color_en = imageColorAllocate($img_en, 0x0F, 0xBD, 0xBF);
// Antialias :
imageTTFText($img_en, 12, 0, 10, 30, $color_en, $font, "AZERTYUIOP");
// No antialias :
imageTTFText($img_en, 12, 0, 10, 50, -$color_en, $font, "AZERTYUIOP");
imagePNG($img_en);
Expected result:
----------------
A clean text, such as the one you could see on a web page (because the
text is never antialiased on a web page).
Actual result:
--------------
