Spot Color
View as MarkdownCreate a die-cut outline around artwork
This sample shows how to build the cut line of a sticker from the transparency of its artwork and write it to a print-ready PDF. Path.GetContour traces the outline of the opaque part of the image with sub-pixel accuracy, Path.Inflate grows it by the bleed and closes the narrow gaps between separate parts, Path.GetOuterContours drops the holes the cutter should not follow, and Path.FitCurves turns the traced polyline into smooth Bezier curves. The outline is stroked with a "CutContour" spot colour, the name cutting plotters and RIPs look for.
