Note "About"
This is a very basic extension for DynaPDF to use Object2D. If you add code, send it to me so I can include it with this example project. still todo: * transparency * other shapes Disadvantages: * Input Object2D may not have sizes correct for the page format used. * PictureShape uses RB picture object. Adding JPEG/TIFF file directly may result into smaller PDF files. * Font handling expects the font names to match between RB and DynaPDF, but some translation is needed there. Greetings Christian
