Path.GetAlphaContour Method (Pipeline)
Applies to: Graphics Mill 12.1, 6.x-12.x (may differ)
Gets the Path object that contains the perimeter of transparency mask.
Namespace:
Aurigma.GraphicsMill.Drawing
Assembly:
Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
Syntax
Parameters
- pipeline
- A pipeline to find contour in.
Return Value
A Path object that contains the perimeter of transparency mask.Remarks
For pixel formats without alpha channel, the contour is a rectangle.
The contour follows the pixel edges, so it has steps. For a smooth contour with sub-pixel accuracy, use GetContour(). The contours of the two methods are offset by half a pixel from each other, so do not mix them.
