[PHP-DEV] PHP 4.0 Bug #8544: ImageTTFText From: frederic.lamsens <email protected>
Date: 01/03/01

From: frederic.lamsens <email protected>
Operating system: Madrake Linux 7.2
PHP version: 4.0.4
PHP Bug Type: GD related
Bug description: ImageTTFText

System:
Linux 2.2.17-21mdksecure #1 SMP Thu Oct 5
Asus Dual PIII 450 Mhz
NVidia Riva128
256 Mb SDRam

PHP Configuration:
./configure --with-mysql
--with-apxs=/usr/local/apache/bin/apxs
--with-ttf --with-gd --with-ldap

GD:
GD Version 1.8.1 (static)
Freetype Version 1.3
FreeType Support enabled
FreeType Linkage with TTF library
PNG Support enabled

When I compiled PHP and used ImageTTFText, the result was not what I expected. Although I can see my input string, the text was shown at an angle of 270 degrees and mirrored. So 'The' looks like '|-' and the 2 next charachters are below the '|-'.

I have been able to solve the problem by changing the php code and recompile the whole thing.

Filename: gdttf.c (located in ext\gd)
Line: around 743

Original code:

#if HAVE_LIBGD13
             pixel = &im->pixels[y3][x3];
#else
             pixel = &im->pixels[x3][y3];
#endif

New code:

pixel = &im->pixels[y3][x3];

By reversing the arguments, the image is now correct.

I hope this information helps ...
