CropRegionToRectangle
Header: | AVL.h |
---|---|
Namespace: | avl |
Creates a region from a rectangular fragment of another one.
Applications: Can be used to obtain a part of a bigger region, but also to enforce specific region frame.
Syntax
void avl::CropRegionToRectangle ( const avl::Region& inRegion, const avl::Rectangle2D& inRectangle, atl::Optional<const avl::CoordinateSystem2D&> inRectangleAlignment, avl::Region& outRegion, atl::Optional<avl::Rectangle2D&> outAlignedRectangle = atl::NIL, atl::Optional<avl::CoordinateSystem2D&> outOutputAlignment = atl::NIL )
Parameters
Name | Type | Default | Description | |
---|---|---|---|---|
inRegion | const Region& | Input region | ||
inRectangle | const Rectangle2D& | Rectangle defining a rotated subregion | ||
inRectangleAlignment | Optional<const CoordinateSystem2D&> | NIL | Adjusts the rectangle to the position of the inspected object | |
outRegion | Region& | Output region | ||
outAlignedRectangle | Optional<Rectangle2D&> | NIL | Input rectangle after transformation (in the region coordinates) | |
outOutputAlignment | Optional<CoordinateSystem2D&> | NIL | Alignment of the output region |
In-place Processing
This function supports in-place data processing - you can pass the same reference to inRegion and outRegion

Optional Outputs
The computation of following outputs can be switched off by passing value atl::NIL
to these parameters: outAlignedRectangle, outOutputAlignment.
