Hi,
I've been reworking Jabier's window rotation code to use the desktop to window affine rather than messing with the SVG viewbox. This is to keep the GUI code out of the SVG handling code (also viewbox doesn't have the concept of rotation so it was a real hack to put it in there). This also unifies how zoom and rotation are handled (and eventually could include flip).
With trunk r15603 most of the work is done so I would like to ask that people try it out.
There are currently two ways to rotate the canvas.
1. Use the rotate spin entry box at the lower right corner of the screen to input an arbitrary rotation value (right click to open a pop- up with preset values). In this case, the rotation is around the center of the window.
2. Use Shift-Ctrl-Scroll wheel to rotate around the current cursor position. Currently the rotation is set to be in increments of 2 degrees. (We can make this a user defined preference.)
Note, this is a work in progress. Axiometric grids are not handled correctly and resize/skew/rotate handles are not rotated with the canvas.
Work is being tracked at http://wiki.inkscape.org/wiki/index.php/Rotati ng_Canvas
Sorry there is no video. I don't have the video creating skill Jabier has...
It would be interesting to know how people use a rotated canvas. Is it with a separate tablet (e.g. Wacom) or with a touch sensitive screen? Yale Zhang has a branch with gestures support. It would be interesting to get this into trunk but it looks like it needs a good review.
