The class provides functions to rotate an image through an arbitrary angle.

Parameters to control the scale of the image when rotation is applied

Enumerator	Value	Description
ERotationScaleModeIgnore		The image is not scaled when rotation is applied, which is the default mode
ERotationScaleModeFitInside		The image will be rotated, and scaled to fit inside the margins of the original image
ERotationScaleModeFitOutside		The image will be rotated, and scaled to fully enclose the margins of the original image

IMPORT_C TReal32

AngleL

(

)

const

Gets the current rotation angle

Returns: The rotation angle

ScaleModeL

(

)

const

Gets the current rotation scale mode

Returns: The rotation scale mode

Specifies the rotation scale mode and angle for the current rotation effect

leave: KErrArgument The level is not in the TRotationScaleMode enumeration or angle is not in the acceptable range.

Parameter	Description
aScaleMode	The rotation scale mode. Range (1) - (3).
aAngle	The rotation amgle. Range (0.0f) - (360.0f).
