u16* _bitmap WoopsiUI::Bitmap::__attribute__ ( (aligned(4))   )  [protected]
void WoopsiUI::Bitmap::blit ( const s16  x,
const s16  y,
const u16 *  data,
const u32  size 
) [virtual]

Blit data to the specified co-ordinates using the DMA hardware.

Parameters:
x The x co-ordinate to blit to.
y The y co-ordinate to blit to.
data The data to blit.
size The number of u16s to blit.

Implements WoopsiUI::MutableBitmapBase.

void WoopsiUI::Bitmap::blitFill ( const s16  x,
const s16  y,
const u16  colour,
const u32  size 
) [virtual]

Fill at the specified co-ordinates using the DMA hardware.

Parameters:
x The x co-ordinate to blit to.
y The y co-ordinate to blit to.
colour The colour to fill with.
size The number of u16s to blit.

Implements WoopsiUI::MutableBitmapBase.

const u16* WoopsiUI::Bitmap::getData ( s16  x,
s16  y 
) const [inline, virtual]

Get a pointer to the internal bitmap data at the specified co-ordinates.

Parameters:
x The x co-ord of the data.
y The y co-ord of the data.
Returns:
Pointer to the internal bitmap data.

Implements WoopsiUI::BitmapBase.

const u16* WoopsiUI::Bitmap::getData (  )  const [inline, virtual]
