glXFontInit( struct _fontInfo *pInfo,
char pixWidth, char pixHeight,
unsigned startChar, unsigned endChar,
unsigned long xmemBuffer )
Initializes a font descriptor that has the bitmap defined in
xmem
. For
bitmaps defined in root memory, use
glFontInit
.
PARAMETERS:
pInfo
is a pointer to the font descriptor to be
initialized.
pixWidth
is the width of each font item (
pixWidth
must be uniform
for all items).
pixHeight
is the height of each font item (
pixHeight
must be
uniform for all items).
startChar
is the offset to the first useable item (useful for fonts for
ASCII or other fonts with an offset).
endChar
is the index of the last useable font item.
xmemBuffer
is a pointer to a linear array of the font bitmap. The
bitmap is a column with the major byte aligned.

for
glPlot
or
glFill
graphics primitive
