Hi Papoj,
if you want more control of the coordinate system you can adjust the values of the viewbox element accordingly. There are no gui options for this yet, but this could be used to e.g. invert the y-Axis.

Hi,
I'm writing here for the first time so nice to meet you all!
I started playing with Inkscape since a few weeks ago and one thing I haven't really understood is the way coordinate system works on Inkscape. First of all, in the UI, the origin lies at the bottom-left corner of the canvas, with y-axis pointing upward (based on what Inkscape displayed when I moved my mouse around the canvas). However, when I created a path through an LPE and printed anchor positions as the path was moved around, I found that the internal coordinate system had y-axis pointing downward, with the origin (0,0) lying somewhere above the canvas instead. Is this an expected behavior? Is there a transformation matrix that transforms the internal positions to the canvas positions?
I compiled Inkscape 0.48 from trunk on OS X Mavericks using clang 3.4 with required libraries compiled using libc++.
If anyone knows about this I'd really appreciate your answer here.
