Description
Initialize the display interface and resets the display.
Renders the pixel located on the given x,y position with the
current set color.
Returns the pixel color located on the given x,y position.
Sets the brightness of the display (level: 0-100).
Returns a non-zero if display controller is busy with the
previous rendering operation. Zero if idle.
Returns the maximum horizontal coordinate.
Returns the maximum vertical coordinate.
Enables/disables clipping.
control definition
CLIP_DISABLE Disable clipping
CLIP_ENABLE Enable clipping
Sets the clipping region with the given coordinates.
Returns left clipping border.
Returns right clipping border.
Returns top clipping border.
Returns bottom clipping border.
Sets the current drawing color.
Returns the current drawing color.
Set the transparent color and enable the transparent color
feature for PutImage().
Graphics Config: USE_TRANSPARENT_COLOR
Disable the transparent color feature for PutImage().
Graphics Config: USE_TRANSPARENT_COLOR
Returns the current status of the transparent color feature of
PutImage().
return value definition
TRANSPARENT_COLOR_DISABLE feature is disabled
TRANSPARENT_COLOR_ENABLE feature is enabled
Graphics Config: USE_TRANSPARENT_COLOR
Returns the current transparent color set by
TransparentColorEnable().
Set the active page. Active page is the buffer used for
rendering. (1)

void SetVisualPage(WORD page)
WORD CopyWindow(
DWORD srcAddr,
DWORD dstAddr,
WORD srcX, WORD srcY,
WORD dstX, WORD dstY,
WORD width,
WORD height)
WORD CopyPageWindow(

BYTE IsDisplayUpdatePending()
void RequestDisplayUpdate(void)
void InvalidateAll()
void InvalidateRectangle(
WORD left,
WORD top,
WORD right,
WORD bottom);
void UpdateDisplayNow()
Description
Set the visible page. Visual page (display buffer ) is the page
shown on the display. (1)
Copies the contents of a window located in the address
defined by srcAddr and the pixel offset set by srcX and srcY
to an address location defined by dstAddr and the pixel offset
set by dstX and dstY. Size of the copied window is set by the
given width and height. (2)
Copies the contents of a window located in the page defined
by srcPage and the pixel offset set by srcX and srcY to
another page defined by dstPage and the pixel offset set by
dstX and dstY. Size of the copied window is set by the given
width and height. (1, 2)
Copies a block of pixels from the given source address
srcAddr with an offset srcOffset to a destination address given
by dstAddr with a given offset dstOffset. Size of the copied
block is set by the given width and height. (2)
Turn on the automatic management of double buffering. All
rendering will be performed on the currently set draw buffer.
Graphics Config: USE_DOUBLE_BUFFERING
Turn off the automatic management of double buffering. All
rendering will be performed on the currently set display buffer.
Graphics Config: USE_DOUBLE_BUFFERING
Returns the status of the display update set by
RequestDisplayUpdate().
Graphics Config: USE_DOUBLE_BUFFERING
Schedule synchronization of the contents of the draw buffer
and the display buffer at the next vertical blanking.
Graphics Config: USE_DOUBLE_BUFFERING
Marks the whole screen area as invalidated.
Graphics Config: USE_DOUBLE_BUFFERING
Invalidates the defined rectangular area in the display buffer.
On the next synchronization of the draw and display buffer,
the invalidated rectangle will be refreshed with the data in
the draw buffer.
Graphics Config: USE_DOUBLE_BUFFERING
Synchronizes the draw and display buffer immediately.
Graphics Config: USE_DOUBLE_BUFFERING
Notes:
1. The API is enabled only if the display controller supports multiple display buffers (or pages).
2. This is an optional feature and is implemented only if the display controller supports addressing of a block of pixel data .
