Parameters
- rect
- Rectangle whose coordinates are to be transformed.
- fromCurrentToOriginal
- When true, the method will treat the values in
rectrectangle as coordinates belonging to the current image, and so it will calculate the corresponding coordinates on the original (incoming) image.When false, the method will treat the values inrectrectangle as coordinates belonging to original (incoming) image, and so the method will calculate the corresponding coordinates on the current image.
Remarks
This method can be used to learn the coordinates of a rectangle on the original (incoming) image, when the coordinates of the rectangle on the current image are known. This might be necessary, since images often undergo different image preprocessing steps, such as deskewing, rotation, etc. Alternatively, this method can provide the coordinates of a rectangle on the current image when its coordinates on the original image are given.
Note: ReduceToBitonal method clears the history of image transforms. After applying this method, Recognition engine treats the bitonal image as if it was the original one.
