System:
Linux 2.2.17-21mdksecure #1 SMP Thu Oct 5

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 ...
