Class CMdaBitmapRotator

Interface status:

deprecated

class CMdaBitmapRotator : public CBase;

Description

Replaced by Image Conversion library - see CBitmapRotator

Rotates a bitmap.

The class offers a simple interface to perform bitmap rotations in clockwise 90 degree increments. The target bitmap is resized as necessary.

Derivation

• CBase - Base class for all classes to be instantiated on the heap.

• CMdaBitmapRotator - Replaced by Image Conversion library - see CBitmapRotator

IMPORT_C static CMdaBitmapRotator* NewL();

Description

Constructs and initialises a new instance of the image rotator.

The function leaves if the image rotator object cannot be created.

Return value

CMdaBitmapRotator * A pointer to the new image rotator object.

IMPORT_C virtual ~CMdaBitmapRotator();

Description

Default destructor.

Frees all associated resources.

IMPORT_C void RotateL(MMdaImageUtilObserver &aObserver, CFbsBitmap &aSrcBitmap, CFbsBitmap &aTgtBitmap, TRotationAngle aAngle);

Description

Begins the rotation of a bitmap clockwise through the specified angle and writes the output to the specified file.

The operation is asynchronous. When it is complete, successfully or otherwise, the callback function MMdaImageUtilObserver::MiuoConvertComplete(TInt) is called, passing the state of the operation.

Parameters

MMdaImageUtilObserver &aObserver The image utility observer interface. CFbsBitmap &aSrcBitmap The bitmap to be rotated. CFbsBitmap &aTgtBitmap The target location for the rotated bitmap. CMdaBitmapRotator::TRotationAngle aAngle The angle through which the bitmap is to be rotated.

IMPORT_C void RotateL(MMdaImageUtilObserver &aObserver, CFbsBitmap &aBitmap, TRotationAngle aAngle);

Description

Begins the rotation of a bitmap clockwise through the specified angle.

The operation is asynchronous. When it is complete, successfully or otherwise, the callback function MMdaImageUtilObserver::MiuoConvertComplete(TInt) is called, passing the state of the operation.

Parameters

MMdaImageUtilObserver &aObserver The image utility observer interface. CFbsBitmap &aBitmap The bitmap to be rotated. This reference is also the target location for the rotated bitmap. CMdaBitmapRotator::TRotationAngle aAngle The angle through which the bitmap is to be rotated.

IMPORT_C void CancelRotation();

Description

Cancels the bitmap rotation operation.

The observer callback function MMdaImageUtilObserver::MiuoConvertComplete(TInt) is not called.

ERotation90DegreesClockwise A clockwise rotation through 90 degrees. ERotation180DegreesClockwise A clockwise rotation through 180 degrees. ERotation270DegreesClockwise A clockwise rotation through 270 degrees. EMirrorFlipHorizontal The bitmap is mirrored about the horizontal axis. EMirrorFlipVertical The bitmap is mirrored about the vertical axis.
