Hello,
I'm trying to create some smooth shaded triangles (Shading Type 4) in a
PDF. I've adapted the helloworld example, supplied with the library, to
draw a triangle with constant (red) colour:
PdfTriangleShadingPattern a = PdfTriangleShadingPattern(0.0, 0.0,
PdfColor(1.0, 0.0, 0.0),
100.0, 100.0,
PdfColor(1.0, 0.0, 0.0),
100.0, 0.0,
PdfColor(1.0, 0.0, 0.0),
&document);
painter.SetShadingPattern(a);
This seems to work seeing that the objects show up in the PDF e.g.
11 0 obj<</Type/Pattern/PatternType 2/Shading 12 0 R>>
endobj
12 0 obj<</BitsPerComponent 8/BitsPerCoordinate 8/BitsPerFlag
8/ColorSpace/DeviceRGB/Decode[ 10 20 10 20 0 1 0 1 0
1]/Filter/FlateDecode/Length 19/ShadingType 4>>
stream
x\9Cc`\00\82\FF \FF\FF\83I \00.\E3 \FB
endstream
endobj
However the actual PDF remains blank. I am unsure whether this is a bug in
the library or if I am calling the wrong sequence of functions.
Help would be greatly appreciated.
