Antialiasing with ImageTTFText

[Anon]

Hi,

I've got problems rendering text on .PNG button background images.
PHP doesn't use the color I allocate and ref in ImageTTFText();

Sample:

$im = @imagecreatefrompng($image); // blue 🙂
$tcolor = ImageColorAllocate($im, 255, 255, 255); // white
ImageTTFText($im, $fsize, 0, $x, $y, $tcolor, $font, "Hello");
ImagePng($im,$outfile);

Resulting text isn't white, but lightblue, so it should be a palette-problem.
Which color-entries makes the ImageTTFText()-Func use of?

anybody?

Try defining a few other colors and see if they work. I know that on blank images the first color you define is the background color, but on createimagefrompng, it should not matter that this is the first color, as there are plenty already there in the first place.

I was just doing some stuff with libgd/freetype and it worked fine.

Are you using the freetype lib or the other ttf lib?

Thank you for your answer, this is what I tried next:

<?php
header("Content-type: image/png");
$im = @ImageCreate (180, 100);
$background_color = ImageColorAllocate ($im, 0, 0, 255);
$text_color = ImageColorAllocate ($im, 255, 255, 255);
for ($i=0;$i<256;$i+=2) {
$dummy = ImageColorAllocate ($im, $i, $i, 255);
}
$font="fonts/TIMR____.TTF";
ImageTTFText($im, 60, 0, 15, 70, $text_color, $font, "white?");
ImagePng ($im);
?>

Result shows no change to previous example.

In fact, there is a nice gradient between the lightblue text and the blue
background, but no white letters🙁.

I use the debian packages. Phpinfo(); lists:

GD Version 1.6.2 or higher
FreeType Support enabled
FreeType Linkage with TTF library for FreeType Support

Same result using Windows9x-gd.dll with TTF.

It works perfectly on my system (Apache 1.3.9 / PHP 4.0.3pl1 / GD 1.6.2 or higher / Win98). I used Arial font.
