nanogui: Thread: problems with GrStretchArea function

Dear all,

        I try to use GrStretchArea funciton, however, it gvies following 
error msg:
"GdStretchBlitEx NOT SUPPORTED on this target."

The nano-X runs on framebuffer mode with debian.

best wishes,
Sally

I need to know your target system bits per pixel (bpp) in order
to say more, since that determines the drivers/fblin*.c file
used.  This driver sounds like it doesn't have the function
implemented, which properly should be NULL, not
defined.

However, check engine/devdraw.c::GdStretchBlit(), and
you will see that there's a hack "#if 1" which should be
changed to "#if 0" to provide a software emulation fix.
This was removed for speed reasons, I think.

Regards,

Greg

Dear Greg,

        Thanks for your email.

        The problem has solved after changing bpp to 16 and  "#if 1" to "if 
0".

        Thank you very much.

best wishes
Sally
