Hi,
I need to keep my desktop area(root window) in an image buffer
and redraw it when necessary. Is there an effective way for doing
this?
I currently use GrReadArea() to keep it in a buffer, and GrArea()
to an offscreen pixmap. Then use GrCopyArea to put it back when
neccessary. But I find it only works for 8bpp and 32bpp under linux
frame buffer when I compile with "MWPF_TRUECOLOR0888".
If I compile with "MWPF_TRUECOLOR565" and run it under 16bpp
, it waits a long time before I can move my mouse. Why?
Is there some way working and no need for recompilation?
,L.C. Chang
