in thread Resizing images with transparent background?

The difference is that PNG uses an alpha channel for transparencies while GIF just sets a certain (and single) color to be transparent. GD just seems to ignore the alpha channel in a PNG file so when a pixel is (0,0,0,0), it just reads the first 3 value which result in a black pixel.

Do you know another module for manipulating images? Besides ImageMagick that is.

    GD has always served my needs till now; but the recent news of libgd stagnation made me make a mental note to look at other options. I tried I::M once and found it to be a huge messy things; 'sides I couldn't possibly bring myself to use anything that spelt magic with a 'k' :)

    I just found Imager available as a PPM for 64-bit, so, I installed that. I obviously can't yet comment upon it's abilities. Seems quite large at 142 files. But, at a cursory glance, it also seems to be very well structured and documented, and that is half the battle.
