Usage

int imaqTransformROI2(ROI* roi, const CoordinateSystem* baseSystem, const CoordinateSystem* newSystem);

Purpose

Rotates and translates a region of interest (ROI) from one coordinate system to another coordinate system within an image.

Parameters

roi	ROI*	The ROI to transform. This parameter is required and cannot be NULL.
baseSystem	const CoordinateSystem*	Describes the base coordinate system. This parameter is required and cannot be NULL.
newSystem	const CoordinateSystem*	Describes the new coordinate system. This parameter is required and cannot be NULL.

Return Value

Type	Description
int	On success, this function returns a non-zero value. On failure, this function returns 0. To get extended error information, call imaqGetLastError().
