Thank you again!
Here is the code I was talking about; my code pretty much does the
job of printing .txt files and related mime types,
http://pastebin.be/17838
But I would love to see your code as well.
Our Read activity (sugar apps are called activities) supports a
plethora of formats (let me just check how it draws on screen), okay
it uses the evince library, meaning I should be able to draw to a
Cairo context right? as the underlying lower level implementation
would be cairo if I am not mistaken? (let me make sure that too). Yep
evince uses poppler for pdf, and that cairo as backends.
Mine for text is here:
http://efax-gtk.cvs.sourceforge.net/viewvc/*checkout*/efax-gtk/efax-gtk/src/utils/text_print_manager.h
http://efax-gtk.cvs.sourceforge.net/viewvc/*checkout*/efax-gtk/efax-gtk/src/utils/text_print_manager.cpp
The guts of it are similar to yours, although it has more twiddly bits.
I do not know anything about OLPC/sugar, so I do not completely
understand all your comments about evince, since evince is a
postscript/pdf display application, rather than a library. The
libraries it uses are as I recall, although it is some time since I
looked, poppler, libspectre and libgs. If evince is the main display
application for sugar, though, then it already comes equipped with
printing via gtk-print, for which purpose it uses poppler/cairo and in
recent versions libspectre/cairo (I think).
