Bug Description
Hi
I am assuming this is a bug, because I expected different behavior. If it is I cannot believe that it is not on here already (I did searched first), so maybe it is not a bug.
Here goes:
At the top of the screen there is a toolbar with fields for entering coordinates for X and Y. When I enter 0 (zero) into the X field the selected object correctly jumps so that its left border is aligned with the left page boundary.
When however I enter 0 (zero) into the Y field the selected object jumps so that its bottom border is aligned with the bottom page boundary. I would expect it to align its top with the top page boundary.
How to replicate:
Open a new page and draw anything. Select it to get the selection rectangle around it. Enter 0 (zero) into the X field on the toolbar. Now enter 0 (zero) into the Y field. The object will jump to the bottom of the page instead of the top.
Version Information:
Inkscape 0.48.4 r9939
Windows 7 64Bit (Latest Service Pack)
Like many drawing applications, Inkscape uses the first quadrant of the Cartesian coordinate system for the drawing area: the origin is in the lower left corner of the page (check the values on the rulers at the top and the left edge of the canvas).

«One confusing aspect is that Inkscape uses a different scale internally. On the canvas, the x and y coordinates increase as one moves right or up. Internally the y coordinate is flipped as per the SVG standard. Thus, (0, 0) is defined from the upper-left corner of the page region internally but at the bottom-left corner in the canvas window. The internal scale is fixed (by default) to 90 dpi. The internal scale is important if you wish to edit by hand an object using the XML Editor. »

The request to change the GUI coordinate system to match the SVG coordinate system, or to support a configurable GUI coordinate system, is tracked in: /bugs.launchpad .net/inkscape/ +bug/170049>
