I am experimenting with different rendering options in PDF viewer. Can you recommend the use case for progressive rendering?
Can you please shed more light on SetProgressiveRendering() in pdftron.PDF.PDFViewCtrl.?
Progressive rendering is useful if your PDF contain lots of elements (e.g. many vector paths, text, or many little images). When progressive rendering is enabled PDFNet will use painter algorithm (http://en.wikipedia.org/wiki/Painter’s_algorithm) to draw the page. This way you may not need to wait very long to see fully rendered page. If your file contains only a single big image, there would be no visible benefit from progressive rendering.
