Draws bitmap in the specified space. The data for the bitmap are stored in
xmem
. This function is like
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 upper left corner of the bitmap, must be evenly divisible by 8.
top
is the upper left corner of the bitmap.
width
is the width of the bitmap, must be evenly divisible by 8.
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 where the text window frame is to start.
y
is the y coordinate of where the text window frame is to start.
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 coordinate + width has exceeded the display boundary.
-2—y coordinate + height has exceeded the display boundary.
