Remarks

IncludeRectangles forms the region of the image that will be considered for feature extraction, any region outside the include region will be ignored.

If IncludeRectangles doesn't have a rectangle then the whole image will be considered as one include region for the feature extraction.

ExcludeRectangles forms the region of the image that will be ignored for feature extraction.

IncludeRectangles are considered first then the ExcludeRectangles will be excluded from the include region.

SvgDocument is the optional SVG document representation of this page if the original format supports loading as SVG. This is created and used by the recognition or processing engine.
