Abstract:
1. A method for transforming image data in an imaging device, the method comprising: defining a source coordinate space with an origin and at least two axes for a source system; receiving at least one of i) coordinates, and ii) dimensions and locations of each of a source foreground object and a source background frame object; receiving a target coordinate space with an origin and at least two axes for a target system; selecting a mapping using at least one Coordinate Change Matrix for mapping between the source coordinate space and the target coordinate space; applying a transformation to modify said source foreground object relative to said source coordinate space to create transformed source foreground object coordinates; capturing said source foreground object coordinates to obtain said foreground object final positioning offset and transform object offset via said Coordinate Change Matrix mapping to a target foreground object offset; clipping said transformed source foreground object coordinates to said coordinates of said source frame object to create clipped transformed source foreground object coordinates; applying an inverse transformation to said clipped transformed source foreground object coordinates to create a source clipping rectangle; and mapping said source clipping rectangle and the source background frame object using said Coordinate Change Matrix, to said target coordinates to create a target clipping rectangle and a target frame object in said target coordinate space.
