Setting the thickness if a line drawn using gd library

[gabrielwai]

I want to draw some lines using the the ImageLine function in the gd library. But can I set the thickness of the line drawn? Or I have to use other functions?

Thx a Lot

$lineWidth = 3;
imagesetthickness ($im,$lineWidth);

The result is not satisfactory. It does not calculate the angel of drawing (so a horizontal line will look thick, a 45-degree line will look much thinner). I heard someone said drawing 4 lines instead of drawing 4 pixels, but I am not sure I can I do that, or is there any other method?
