Add support for print preview

GoogleCodeExporter commented 9 years ago

It'd be nice to add support for print preview to CEF.  At the moment, CEF 
allows you to print the contents of a frame, but CEF creates and manages the 
device context itself.  In order to handle print preview, I think we'd want a 
function like PrintToDC that would allow a client to pass in an HDC and page 
number (or CefDeviceContext, to keep it platform-neutral).  CEF would render 
the given page to the DC, but not actually print anything.  The client could 
then use the rendered DC to display a print preview window.

Do we have any thoughts on an initial approach for this? The project I'm 
currently working on requires some type of print preview, so I'm interested in 
potentially adding this to CEF3, but I probably need some pointers on where 
exactly to start.

Is the functionality that Chrome uses to render PDFs for print preview 
available to us in CEF or is that unavailable in Chromium?

@comment#5: The Chrome PDF plugin uses custom pepper extensions and is not open 
source, so we can't (easily) use it with Chromium.

Google open sourced (BSD) the Chrome PDF rendering engine just a few days ago, 
see PDFium:

PDFium already got into Chromium's trunk:
http://src.chromium.org/viewvc/chrome/trunk/src/pdf/pdfium/

Interesting, this is the same rendering engine that is used in Foxit PDF 
Reader, the documentation link from wiki page leads to Foxit SDK.

Wow, that's fantastic news. Marshall, I assume this would be a good way forward 
for this?

@comment#8-9: Yes, good news. If we're lucky this will become part of the 
Content API in the context of 
https://code.google.com/p/chromium/issues/detail?id=311308.

Do we need a separate issue in the Chromium issue tracker for migrating print 
preview support to the Content API? Just asking because the item you mentioned 
explicitly limits its scope to exclude print preview.

Starting with https://crbug.com/170859 Chromium now uses PDF instead of 
metafiles for printing. We'll need to figure out how to move printing in CEF to 
PDF as well.
