IMPORT_C TReal32

AngleL

(

)

const

Gets the current rotation angle

ScaleModeL

(

)

const

Gets the current 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.

TRotationScaleMode aScaleMode	The rotation scale mode. Range (1) - (3).
TReal32 aAngle	The rotation amgle. Range (0.0f) - (360.0f).

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

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
