Syntax

short FastRotate (ILEADRaster *pRaster, short iAngle);

Overview

Refer to Examining and Altering Bitmaps.

Remarks

(Document/Medical only) Rotates the bitmap in 90-degree increments, in a faster way than is possible with the Rotate method.

Valid rotations are +-90, +-180, +-270, or +-360. Positive values are clockwise; negative values are counterclockwise.

Please note that this is only a viewport rotation. The "rotated" data is not saved.
