I'm working on getting printing to work with my WinCairo port of WebKit. Following the model of the CG implementation, I was planning on using the spoolPages method of the IWebFrame interface.
This method is declared as follows (see ~ line 191 in WebKit\win\WebFrame.h): virtual HRESULT STDMETHODCALLTYPE spoolPages (HDC printHDC, UINT startPage, UINT endPage, void* ctx); The 'ctx' term appears to be a suitable graphic library context associated with the print HDC. I was surprised to see that this was necessary, as you can usually convert from a device context to the platform graphic context abstraction. This would allow the details of the drawing context to be internal to WebFrame. As it is now, the void* passed in must be created externally from the HDC which in my case means that the Cairo library must now be linked into the main application (which does not otherwise have any need to know about Cairo). Am I misunderstanding the purpose of the ctx argument? Or could I propose a patch to refactor this to avoid needing this final argument.
