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

Creates an elliptic region of given bounding rectangle.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax


public static void CreateEllipseRegion(
	AvlNet.Rectangle2D inEllipse,
	AvlNet.CoordinateSystem2D? inEllipseAlignment,
	int inFrameWidth,
	int inFrameHeight,
	out AvlNet.Region outRegion,
	out AvlNet.Rectangle2D outAlignedEllipse
)

Parameters

inEllipse
Type: AvlNet.Rectangle2D
inEllipseAlignment
Type: System.Nullable<AvlNet.CoordinateSystem2D>
Adjusts the ellipse 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 ellipse!)
inFrameHeight
Type: System.Int32
Height of the created region's frame (not to be confused with the height of the ellipse!)
outRegion
Type: AvlNet.Region
Output region
outAlignedEllipse
Type: AvlNet.Rectangle2D

Description

The operation creates a region containing pixels lying inside an ellipse which is described by its bounding 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 ellipse exceeds these dimensions, the output region will be cropped.

Examples

CreateEllipseRegion run with a sample rectangle.
