FastBlendBitmap(const TPoint &, CFbsDrawDevice *, const TRect &, CGraphicsContext::TDrawMode, TInt)

TInt FastBlendBitmap ( const TPoint & aDest,
CFbsDrawDevice * aSrcDrawDevice,
const TRect & aSrcRect,
CGraphicsContext::TDrawMode aDrawMode,
TInt aShadowMode
) [pure virtual]

Performs blended blitting. The interface can selectively supports various combinations of source and destination. Assumes that aSrcRect is contained by the source device. Assumes that the resulting destination rectangle is contained by the destination device.

Parameters

const TPoint & aDest Logical coordinates of the position in the target that the result should be drawn to.
CFbsDrawDevice * aSrcDrawDevice Draw device that will act as the source of the blit.
const TRect & aSrcRect The rectangular region of the source to be blitted.
CGraphicsContext::TDrawMode aDrawMode Current draw mode
TInt aShadowMode Current shadow mode

FastBlendBitmap(const TPoint &, const TUint32 *, TInt, const TSize &, const TRect &, TDisplayMode, CGraphicsContext::TDrawMode, TInt)

TInt aShadowMode
) [pure virtual]

Performs blended blitting. The interface can selectively supports various combinations of source and destination. Assumes that aSrcRect is contained by the source device. Assumes that the resulting destination rectangle is contained by the destination device.

Parameters

const TSize & aSrcSize Size of the source bitmap in pixels.
const TRect & aSrcRect The rectangular region of the source to be blitted.
TDisplayMode aSrcDisplayMode Display mode of the source bitmap
CGraphicsContext::TDrawMode aDrawMode Current draw mode
TInt aShadowMode Current shadow mode
