pvginkel / chromepdfviewer Goto Github PK

Can you document the difference between this project and the PdfViewer project? I'm not sure which one I should be using.

I am unable to make the print function print without scaling. I need to have the output printed at native scale, at the top left of the page. There seems to be options for this in the dll RenderPDFPageToDC function to do exactly what I want (fitToBounds, stretchToBounds, keepAspectRatio, centerInBounds), but none of the options is working for me.

Printing is very slow.

I've looked at the Chrome source and Chrome seems to do the following:

• Render everything to an EMF;
• Use the EMF to render on a Canvas;
• Let the browser take it from there.

The current implementation renders directly to the printer DC. I've implemented this, but printing from the EMF to the printer DC, but that doesn't seem to help. The only clue I could find was that it looks like (I may be wrong) that text isn't rendered as text, but as vectors. I however don't know enough about .NET printing or how the library works to fix this.

Any help is sincerely appreciated.
