Description

Use TiRotationDisplay for rotating a bitmap in real-time. The lower left pixel of the bitmap is used for the transparent color. To specify the angle of rotation, set the RotationAngle property.

The performance depends on the number of rotations per second and the size of the bitmap. The performance is not impacted by the size of the control, only the portion where the bitmap is displayed is actually rotated. To increase performance, decrease the bitmap size or decrease the rate at which the RotationAngle property is changed.
