[Geomoose-users] PDF Printing - how to layer background transparent?

[Dan Little]

I'll have to look into this, I imagine it's because the Image is getting converted to RGB, then having transparency applied to it.  The original "image stacking" code inside of the printing software was originally only tested against GIF and JPEG layers.  We'll need to do some more work to make the 24-bit PNGs look good.
