Yes it could help with DPI. Since you could use it to rebuild both QImage by replaying the original QPicture on a QImage.
But my problem with it being binary is that a diff is of little value. What I am hopping with the text format is to be able to run diff, and get this output: -LINE 11.0 -12.1 34.3 2.3 QPEN(255,0,0) +LINE 12.0 -12.1 34.3 2.3 QPEN(255,0,0) And of course if you run that on a big document it might not be that helpfull, but on smaller unit tests, I am thinking it could give an idea of what went wrong. -- Cyrille Berger Skott _______________________________________________ calligra-devel mailing list calligra-devel@kde.org https://mail.kde.org/mailman/listinfo/calligra-devel
