Extract paths and shapes with iTextSharp

Question

iTextSharp supports creation of shapes and paths with PdfContentByte class, there you can set colors and paint curves and basic elements ... is there a mechanis

Answer 1

That's not supported in iTextSharp. The reason: parsing for text returns TextRenderInfo objects, parsing for images returns ImageRenderInfo objects, but in which form should we return GraphicsRenderInfo? It's hard to find something generic, and painting to a graphics context is too specific.

The idea is that you write your own parser, as I did for instance for removing OCG layers: OCGParser. This part of iText hasn't been ported to iTextSharp yet, but maybe you can use it for inspiration.

Note that you're actually building PDF to image functionality. Aren't there other products who already support this out of the box?
