Construction and destruction

`TImageBitmapUtil()`

IMPORT_C TImageBitmapUtil();

Description

Default constructor for this class.

Member functions

`Begin()`

IMPORT_C void Begin();

Description

Requests a lock for the current bitmap from the font & bitmap server and sets the current position in the bitmap to the first pixel.

`Begin(const TPoint &)`

IMPORT_C TBool Begin(const TPoint &aPosition);

Description

Requests a lock for the current bitmap from the font & bitmap server and sets the current position in the bitmap to aPosition.

Parameters

const TPoint &aPosition

The position to move to.

Return value

TBool

A boolean indicating if the position was out of bounds. EFalse if the position was out of bounds, otherwise ETrue.

`End()`

IMPORT_C void End();

Description

Releases a lock previously acquired using TImageBitmapUtil::Begin().

`SetBitmapL(CFbsBitmap *)`

IMPORT_C void SetBitmapL(CFbsBitmap *aBitmap);

Description

Sets the current bitmap to aBitmap.

Parameters


                                 						CFbsBitmap *aBitmap

A pointer to the bitmap.

Leave codes

KErrNotFound

The bitmap or its handle is NULL or its display mode is not recognised.

`SetPixel(TUint32)`

IMPORT_C void SetPixel(TUint32 aPixelIndex);

Description

Sets the pixel value at the current bitmap position using aPixelIndex.

Post-Condition

The current position is updated.

Parameters


                                 						TUint32 aPixelIndex

The pixel index.

`SetPixels(TUint32 *,TInt)`

IMPORT_C void SetPixels(TUint32 *aPixelIndex, TInt aNumberOfPixels);

Description

Sets an array of pixel values, starting at the current bitmap position using the values supplied in aPixelIndex.

Post-Condition

The current position is updated.

Parameters

`TUint32 *aPixelIndex`	A pointer to the first element in the array.
`TInt aNumberOfPixels`	The number of elements in the array.

`SetPos(const TPoint &)`

IMPORT_C TBool SetPos(const TPoint &aPosition);

Description

Sets the current position in the bitmap to aPosition.

Parameters

const TPoint &aPosition

The position to move to.

Return value

TBool

A boolean indicating if the position was out of bounds. EFalse if the position was out of bounds, otherwise ETrue.
