I have posted some notes on how I got alpha blending working with PNG images (background and moving image) in the Development Forum if anyone needs more help.
As I used the graphics.c library (the same as LUA player), I am still confused about one thing:
I got alpha blending (transparency) to work when blitting image to image but blitting image to screen still doesn't work for me:
blitalphaimagetoimage() WORKS (transparent color is dropped).
blitalphaimagetoscreen() DOESN'T (displays fully transparent image)
I've spent too much time on it and will use the image to image as a work-around but wonder if there's a bug in the code? (seems I've seen this mentioned someplace else before).
Any ideas?
