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.
void glSetBrushType( int type )
Sets the type of brush type and controls how pixels are drawn on the
screen until the next call to glSetBrushType.
PARAMETER: type is the type of the brush. The four macros
described below have been defined for valid values to pass to the
function.
All four brush types can be used to display text or bitmaps. Do
not use GL_BLOCK for glPlot or glFill graphics primitive
functions.

Description
Effect
GL_SET
Pixels specified by subsequent gl
functions will turn on the LCD
pixels
LCDPix =
LCDPix | newPix
GL_CLEAR
Pixels specified by subsequent gl
functions will turn off the LCD
pixels
LCDPix =
LCDPix & ~newPix
GL_XOR
Pixels specified by subsequent gl
functions will toggle the LCD pixels
LCDPix =
LCDPix ^ newPix
GL_BLOCK
Pixels specified by subsequent gl
functions will be displayed on the
LCD as is
LCDPix = newPix
