This is incorrect. Bitblt is a device-dependent function to
move bits from one area to another. The nano-X GrBitmap() function is
used to draw monochrome bitmaps in nano-X. It takes a window id,
graphics context, x, y, w, h, and an imagebits ptr. The imagebits are drawn
using the current gc foreground color, and if UseBackground is set, the background
bits are drawn using the bg color.
Micro-windows supports 256 color bitmaps with DrawImage().

: blt for "block transfer"]

: I think a GGI driver would be a thing to have in this initial
: testing/developing/hacking period. This would mean (for me)
: being able to hack it, since I can't get framebuffers to work on
: either machine I use (Trident board at work, MACH32 at home).
:
: As to your problem... wouldn't GGI on top of svgalib help? Or
: GGI on KGI if available for your hardware? (I personally plan to
: use GGI/svgalib in the beginning, since I don't want to install
: X at home)
My version of nano-X and micro-windows runs on top of
SVGAlib, which runs on all versions of linux. That's the reason I wrote it.
Any linux user can use and develop with nano-X. No need for the
ridiculously hard-to-setup framebuffers. Of course, they're supported too.
