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.
See also: CBitmapRotator
Rotation angle.
Enumerator | Value | Description |
---|---|---|
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. |
IMPORT_C | ~CMdaBitmapRotator | ( | ) | [virtual] |
Default destructor.
Frees all associated resources.
IMPORT_C void | CancelRotation | ( | ) |
Cancels the bitmap rotation operation.
The observer callback function MMdaImageUtilObserver::MiuoConvertComplete() is not called.
IMPORT_C CMdaBitmapRotator * | NewL | ( | ) | [static] |
Constructs and initialises a new instance of the image rotator.
The function leaves if the image rotator object cannot be created.
IMPORT_C void | RotateL | ( | MMdaImageUtilObserver & | aObserver, |
CFbsBitmap & | aSrcBitmap, | |||
CFbsBitmap & | aTgtBitmap, | |||
TRotationAngle | aAngle | |||
) |
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() is called, passing the state of the operation.
Parameters | |
---|---|
aObserver | The image utility observer interface. |
aSrcBitmap | The bitmap to be rotated. |
aTgtBitmap | The target location for the rotated bitmap. |
aAngle | The angle through which the bitmap is to be rotated. |
IMPORT_C void | RotateL | ( | MMdaImageUtilObserver & | aObserver, |
CFbsBitmap & | aBitmap, | |||
TRotationAngle | aAngle | |||
) |
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() is called, passing the state of the operation.
Parameters | |
---|---|
aObserver | The image utility observer interface. |
aBitmap | The bitmap to be rotated. This reference is also the target location for the rotated bitmap. |
aAngle | The angle through which the bitmap is to be rotated. |
