I done some tests and I noticed some funny results : First time I used
the 0.91 :
With the "0.91" version I noticed that PNG image with RGB=0,0,0 and
Alpha=0 for transparent color was display in black (not transparent) but
PNG image with RGB=255,255,255 and Alpha=0 (or no alpha) for transparent
color was diplay with ritght transparent at this part.
After I download nano-X sources from the CVS repository Version "pre
0.92" and I noticed that there's a different comportment :
An image PNG with RGB=0,0,0 (or RGB=255,255,255) and Alpha=0 for
transparent color was right display, but normaly an image with
RGB=255,255,255 and no Alpha was display in white for parts (and not
with transparent colors). Maybe there's several difference between the
0.91 and the "pre 0.92"...
Anyway I work now with the last CVS version (pre 0.92), but this
difference is strange. Maybe a fixed bug ?

Any colors informations was took with gimpĀ·

Right ! It's that what I noticed for the 0.91 version (but not with pre
0.92). With this last version alpha seems to be set.
