Meziantou.FrameworkPdfPatch Class
A patch of a Coons or tensor-product patch mesh (ISO 32000-2, 8.7.4.5.7 and 8.7.4.5.8): four cubic Bézier curves around the patch and a color at each corner.
public sealed class PdfPatchRemarks
The twelve boundary points go around the patch: the corner p00, then the curve up to the corner p03, the curve across to p33, the curve down to p30 and the curve back to p00 (figure 49 of the specification), each curve given by its two control points and its end. The colors are those of the corners p00, p03, p33 and p30.
