glXGetFastmap
void glXGetFastmap(int left, int top, int width, int height,
unsigned long xmemptr);
DESCRIPTION
Draws bitmap in the specified space. The data for the bitmap are stored in
xmem
. This
function is similar to
glXPutBitmap()
, except that it's faster. The bitmap must be
byte-aligned. Any portion of a bitmap image or character that is outside the LCD display
area will be clipped.
This function call is intended for use only when a graphic engine is used to interface with
the LCD/keypad module.
PARAMETERS
left
the
x
coordinate of the top left corner of the bitmap (
x
must be
evenly divisible by 8).
top
the
y
coordinate in pixels of the top left corner of the bitmap.
width
the width of the bitmap (must be evenly divisible by 8).
height
the height of the bitmap.
xmemptr

RAM storage address of the bitmap.
