			TInt	aFrameFormat
		)	[static]

Two-phased constructor.

Since: 3.2

Parameters

TDes8 & aBuffer	A descriptor reference to buffer containing the image data.
const TSize & aDimension	The dimensions of the corresponding image data.
TInt aFrameFormat	The frame format of the corresponding image data.

NewL(RChunk &, TInt, TInt, TInt, const TSize &, TInt)

CVisualFrameImpl *	NewL	(	RChunk &	aChunk,

Parameters

RChunk & aChunk	An RChunk reference to buffer containing the image data.
TInt aSize	The amount of image data in bytes.
TInt aMaxSize
TInt aDataOffset	The offset value specifying the location of the image data in the chunk.
const TSize & aDimension	The dimensions of the corresponding image data.
TInt aFrameFormat	The frame format of the corresponding image data.
