Draws bitmap in the specified space. The data for the bitmap are stored in
xmem

glXPutBitmap
, except that it is faster. The restriction is that the bitmap must be byte-aligned.
Any portion of a bitmap image or character that is outside the LCD display area will be clipped.
PARAMETERS
left
is the top left corner of the bitmap, must be evenly divisible by 8, otherwise truncates.
top
is the top left corner of the bitmap.
width is the width of the bitmap, must be evenly divisible by 8, otherwise truncates.
height is the height of the bitmap.
bitmap is the address of the bitmap in xmem .
RETURN VALUE
None.
SEE ALSO
glXPutBitmap, glPrintf
Defines a text-only display window. This function provides a way to display characters within the text
window using only character row and column coordinates. The text window feature provides end-of-line
wrapping and clipping after the character in the last column and row is displayed.
NOTE: Execute the TextWindowFrame function before other Text... functions.
PARAMETERS
*window is a window frame descriptor pointer.
*pFont is a font descriptor pointer.
x
is the x coordinate of the top left corner of the text window frame.
y
is the y coordinate of the top left corner of the text window frame.
winWidth is the width of the text window frame.
winHeight is the height of the text window frame.
RETURN VALUE
0—window frame was successfully created.
-1—
x coor width has exceeded the display boundary.
-2— y coor height has exceeded the display boundary.
void glXPutFastmap(int left, int top, int width,
