I am trying to run a basic script that displays an existing jpeg image
and writes some text over it. Sounds simple, but I cannot seem to be
able to colour the font correctly. In the example below it should be
black but it comes out orange. In fact, even if I change the colour to
0, 0, 255 it's orange.
I've read in the PHP documentation (the user contributed notes) that
there are issues with jpeg font colouring. But I've not seen any
details. Can anyone shed light on this for me please?
The example code below is called as a function. The $image variable is
a path to the existing image file and the $ttf variable is a path to a
TrueType font. The $text variable contains a text string.
header("Content-type: image/jpeg");
$base_image = imagecreatefromjpeg($image);
$font = $ttf;
$fontcolor = imagecolorallocate($base_image, 0, 0, 0);
imagettftext($base_image, 18, 0, 10, 100, $fontcolor, $font, $text);
imagejpeg($base_image); imagedestroy($base_image);
Cheers,
Si.
