Creating a barcode image with imagettftext (cant turn of antialiasing on the text)

[gremin]

I have tried all things but cannot reverse the color to turn off the AA on the text that is created... can someone take a look please and let me know what i need to do? Thanks in advance - as it is the last bit i need to sort. BTW: The font is a bar-code font and the AA on the image stops the reader picking up the image.

$img = imagecreate ($image_width, $image_height);
$black = imagecolorallocate ($img, 0, 0, 0);
$white = imagecolorallocate ($img, 255, 255, 255);
imagefilledrectangle($img, 0, 0, $image_width, $image_height, $white);
imagettftext ($img, 20, 0, 3, 30, $black, "../includes/fonts/39251.TTF", "" . $item["consignment_no"] . "");
imagepng ($img, $item["consignment_no"] . ".png", 100);

Try swapping the lines that set $black and $white over.

As you know, antialiasing is turned on and off by negating the colour index (in this case using -$black instead of $black). But because $black is the first colour you assigned, it gets the index 0. And -0==0.

By swapping the assignments over, the background colour $white gets colour index 0, and $black gets index 1, and now imagettftext can tell the difference between 1 and -1.

Ahhh!!! Got it... I was trying the -$black thing before.. But didnt realise that you was to swap the order of the color vars!.

Thanks HEAPS!!!
