Why?
AFAIK in cgi you can not use the hardware acceleration.
Because color manupulation in 16-bit depth may be slower than in 8-bit,
and because even withouh acceleration, OS drawing functions may be much
better optimized then FPPCanvas ones.
Maybe, maybe not.
In case of gtk I doubt that *many* functions are much faster.
In my measurements the difference between 16 vs 8bit was not
big. It made a big difference if your bitmap is 16bit. I recommend to
not use the default fp memory image. Writing a 8bit is easy. It would
be nice if fpimage would provide some other memory image
implementations. For example 8bit RGB, RGBA and
Grayscale.
Good idea, I can easily add these.
Michael.
