Methods

AdjustCropAndFindOffsetForFrameBounds(Rectangle, ref Rectangle)

Combines the crop rectangle with the frame bounds and updates the crop rectangle to be relative the frameBounds. Also calculates the offset of the frame inside the original crop rectangle

Declaration

public static Point AdjustCropAndFindOffsetForFrameBounds(Rectangle frameBounds, ref Rectangle cropRectangle)

Parameters

Type	Name	Description
System.Drawing.Rectangle	frameBounds	The System.Drawing.Rectangle defining the frame in the canvas
System.Drawing.Rectangle	cropRectangle	The System.Drawing.Rectangle defining the area to crop from the canvas. Also defines the size of the new Canvas. Will be updated to reflect the actual rectangle to crop from the frameBounds. If crop rectangle is outside the frame, System.Drawing.Rectangle.Empty will be returned.
