If you want to get the best result in monochrome font rendering, change render_mode to FT_LOAD_RENDER. It's the last parameter of FT_Load_Glyph() function (in gdft.c).

For negative image you must add one line after the $grayColor computation:
$grayColor = ~ $grayColor & 0x7FFFFFF;

This function is very simular to imageffttext(), you may find the information provided on its manual page helpful:

When compiling PHP with FreeType 2 support, you'll probably have some problems if - for example - you use debian and didn't compile freetype2 yourself...
If configure fails after saying "If configure fails, try --with-xpm-dir..." you most likely have FreeType1 installed, but not freetype2 ...
Do this as root :
apt-get install libfreetype6-dev
It took me some time to find out that apt-get install freetype2 is actually installing freetype1 ...

I found myself in need of an align right function and found one on the imagepstext manual page. I can't imagine I'm the only person who's needed to use this, so here's a slightly modified version that works with imagefttext:
<?
function align_right($string, $fontfile, $imgwidth, $fontsize){
$spacing = 0;
$line = array("linespacing" => $spacing);
list($lx,$ly,$rx,$ry) = imageftbbox($fontsize,0,$fontfile,$string,$line);
$textwidth = $rx - $lx;
$imw = ($imgwidth-10-$textwidth);
return $imw;
}
?>

I wrote a bit of code to gather all the .ttf files in the directory with this script, and randomize them to write text on a header image for my site. The only catch is the font files have to be named 1.ttf, 2.ttf etc etc.
<?php
srand((double)microtime()*1234567); $image = imagecreatefromjpeg(rand(1,exec('ls *.jpg | wc -l')) . ".jpg"); $font = rand(1,exec('ls *.ttf | wc -l')) . ".ttf"; $textcolor = imagecolorallocate($image,0,0,0); $text1 = "shenko.homedns.org"; imagettftext($image, 50, 0, 20, 50, $textcolor, $font, $text1); header("Content-type: image/jpeg"); imagejpeg($image,'',90); imagedestroy($image); ?>

After spending the evening with some work on automatically generated images, I had the idea to switch of anti-aliasing (looking, if some font would look better that way), which turned out not to be quite so easy.
Actually you have to use the negative of the desired color to switch of antialising. I include the corresponding line from my code (line split up):
// USE NEGATIVE OF DESIRED COLOR TO SWITCH OF ANTI-ALIASING
ImageFTText ($neuesBild,$fontsize,$fontangle,$TextPosX,$TextPosY,
-$custom_fg,$fonttype,$text,array());

Thanks for the script! I modified it to show several fonts that I was wanting to use. I am using GD-2.0.7, FreeType-2.1.3(text rotation fix,among others), and PHP-4.2.3 and had to include the array information to get it to work.
Code change follows:
$fontfile="/usr/local/fonts/ttf/bookantbd.ttf";
// Waterfall of point sizes to see what Freetype 2's autohinting looks like:
//
for($i=4;$i<=12;$i++){
ImageFtText($image,$i,0,10,(280+$i*14),$forecolor,$fontfile, bookantbd . $i . ". " . $string, array("linespacing" => 1.0));
}

If you're interested in turning off FreeType hinting, search for the following line in the gd source (gdft.c):
err = FT_Load_Glyph (face, glyph_index, FT_LOAD_DEFAULT);
and replace it with
err = FT_Load_Glyph (face, glyph_index, FT_LOAD_NO_HINTING);
Recompile GD, and vo
