Process(TRequestStatus &, const MIHLBitmap &, const TRect &, MIHLBitmap &, const TRect &)

TInt	Process	(	TRequestStatus &	aStatus,
			const MIHLBitmap &	aSrcBitmap,
			const TRect &	aSrcRect,
			MIHLBitmap &	aDstBitmap,
			const TRect &	aDstRect
		)	[pure virtual]

Process rectangle from source bitmap to a rectangle in destination bitmap. Scaled area can be also rotated and/or mirrored during process. See full description from MIHLScaler header.

Since: 3.0

Parameters

TRequestStatus & aStatus	Process request status reference.
const MIHLBitmap & aSrcBitmap	Source bitmap reference.
const TRect & aSrcRect	Rectangle that is processed from source bitmap.
MIHLBitmap & aDstBitmap	Destination bitmap reference.
const TRect & aDstRect	Rectangle that is filled in destination bitmap.

SetFilter(MIHFilter *)

void

SetFilter

(

MIHFilter *

aFilter

)

[pure virtual]

Set filter. For future use, not used currently!
