AVL.CreateRectangleRegion(AvlNet.Rectangle2D, AvlNet.CoordinateSystem2D?, int, int, AvlNet.Region, AvlNet.Rectangle2D)

Creates a region corresponding to a given rectangle.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax


public static void CreateRectangleRegion(
	AvlNet.Rectangle2D inRectangle,
	AvlNet.CoordinateSystem2D? inRectangleAlignment,
	int inFrameWidth,
	int inFrameHeight,
	out AvlNet.Region outRegion,
	out AvlNet.Rectangle2D outAlignedRectangle
)

Parameters

inRectangle
Type: AvlNet.Rectangle2D
inRectangleAlignment
Type: System.Nullable<AvlNet.CoordinateSystem2D>
Adjusts the rectangle to the position of the inspected object, or null.
inFrameWidth
Type: System.Int32
Width of the created region's frame (not to be confused with the width of the rectangle!)
inFrameHeight
Type: System.Int32
Height of the created region's frame (not to be confused with the height of the rectangle!)
outRegion
Type: AvlNet.Region
Output region
outAlignedRectangle
Type: AvlNet.Rectangle2D

Description

The operation creates a region containing pixels lying inside the specified rectangle.

The inFrameWidth and inFrameHeight parameters most often should be set equal to the dimensions of the image this region will be used with. If the input rectangle exceeds these dimensions, the output region will be cropped.
