76 eDisplay (OP7200)
Draws bitmap in the specified space. The data for the bitmap are stored in
xmem
. This is like
glXPutBitmap
, except that it’s 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 upper left corner of bitmap, must be evenly divisible by 8
top is the left top corner of the bitmap
width is the width of the bitmap
height
is the height of the bitmap
bitmap is the address of the bitmap in xmem
SEE ALSO
glXPutBitmap, glPrintf
Gets a bitmap from the LCD page buffer and stores it in xmem RAM. This function automatically calls
glXGetFastmap if the bitmap is byte-aligned (left edge and width are each evenly divisible by 8).
PARAMETERS
x is the x coordinate of the left edge of the bitmap (in pixels)
y is the y coordinate of the top edge of the bitmap (in pixels)
bmWidth is the width of the bitmap (in pixels)
bmHeight is the height of the bitmap (in pixels)
xBm is the address of the bitmap in xmem RAM
SEE ALSO
glXPutFastmap, glPrintf
void glXPutFastmap(int left, int top, int width,
int height, unsigned long bitmap);
void glXGetBitmap(int x, int y, int bmWidth,
int bmHeight, unsigned long xBm);
