: I have an application with xbm type data compiled in as a bitmap.
:
: I am using sections of this bitmap to represent each letter.
Hmmm.... It looks like you need the new GrNewBitmapFromData
and GrNewPixmapFromData functions I wrote the night after
I released pre7 ;-)
Most likely you will need to both bit-reverse and then byte-swap
the pixmap data before calling GrCopyArea. That's what my
routines do.
I will be releasing the pixmap stuff very shortly, as part of my new
XtoNX.h Xlib-to-Nano-X conversion header file. I've ported
xfreecell with very few source modifications directly from Xlib
to Nano-X. Let me know if you want a copy of the functions sooner
and I'll send them to you.
Regards,
Greg

: It looks like:
: #define PalmFont0_width 1168
: #define PalmFont0_height 11
: #define PalmFont0_x_hot 0
: #define PalmFont0_y_hot 0
: static unsigned char PalmFont0_bits[] = {
: 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
: 0x00,
: 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
: 0x00,
: 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
: 0x00,
: ... and so on...

: In X11, the code to load it looks like:
:
: palmFontBitmap = XCreateBitmapFromData(display, rootWindow,
: (char *)PalmFont0_bits,
: PalmFont0_width, PalmFont0_height);
:
: I figured in NanoX it should look something like this:
:
: palmFontBitmap = GrNewPixmap(PalmFont0_width, PalmFont0_height, (void
: *) NULL);
:
: GrBitmap(palmFontBitmap, gcNormal, 0,0,
: PalmFont0_width, PalmFont0_height,
: (GR_BITMAP *) PalmFont0_bits);
:
:
: To actually make use of sections of it I do the following:
:
: GrCopyArea(paintWindow, gc,
: x, y,
: end-start, PalmFont0_height,
: palmFontBitmap,
: start, 0,
: MWROP_SRCCOPY);
