Transparent PNG
Oct 2nd, 2008, 10:37am  
Tried to search for this and have got limited success, but really not getting it. Looked at the blend & mask functions but can't figure them out.

I was to load an image of a crosshair which has an png alpha channel, that I can then move around with the mouse.


Has anyone got a small example of loading a png with an alpha channel I can use as a starting point?

You know, I don't know what I was doing yesterday, but that wasn't working for me.

*hangs head in shame*

Thanks very much!

make sure you save out PNG with ahpha channel 32 bit format.  If still problems then try 32 bit TGA and create an alpha channel from within photoshop - so that you have your 3 RGB channels plus an alpha.
