if I generated an image:
first using imagecreate();
then coloring it over with imageline() //for my project yes this works out excelent.

I would like to import alternate PNG images and place them on top of my generated image.

However it gets better, I need to alpha out the color #6DB3D0.

or:
R: 109
G: 179
B: 208

I should say for the record, its not specificly THIS color, thats it's purest form, I also would like to make neighboring pixels transparent accuratly in comparision (so if a pixel was "half" that color and half black.. it would end up placing down a half black color.. if that makes any sense).

How would I do this? Please use an example if possible.

Been a while since I was actively using gd, but since nobody's answered for a while I'll give this a shot. Have you considered setting this color with
imagecolorallocate()
and then doing an
imagecolortransparent()
on it?
