Detailed Description

The class that extends PdfShading class and is in charge of Shading Dictionary with free-form Gouraud-shaded triangle mesh type.

The class that extends PdfShading class and is in charge of Shading Dictionary with free-form Gouraud-shaded triangle mesh type. The area to be shaded is defined by a path composed entirely of triangles. The colour at each vertex of the triangles is specified, and a technique known as Gouraud interpolation is used to colour the interiors. The object shall be represented as stream containing a sequence of vertex data. Each vertex is specified by the following values, in the order shown: f x y c1 ... cn where: f - the vertex's edge flag, that determines the vertex is connected to other vertices of the triangle mesh. For full description, see ISO-320001 Paragraph 8.7.4.5.5 x, y - vertex's horizontal and vertical coordinates, expressed in the shading's target coordinate space. c1...cn - vertex's colour components. If the shading dictionary includes a Function entry, only a single parametric value, t, shall be specified for each vertex in place of the colour components c1...cn.
