Indeed, I already had a rudimentary rotatable desktop working a while ago; it was only a small coding effort.<br> What popped up were some UI questions:<br>- page display<br>- boundingbox, do we want it to rotate too or not?<br>- thingies for scaling, shearing, rotating, should they rotate too?<br>- horizontal/vertical directions for dragging objects with ctrl, should they rotate too?<br>Etc...<br><br>Related: it can be nice to have different scales in x and y dir. If rotating works, then it should be programmed such that any reasonable transform matrix works...?<br><br>Cheers,<br> &nbsp;Johan<br><br>----- Reply message -----<br>Van: &quot;Krzysztof Kosiński&quot; &lt;tweenk.pl@...400...&gt;<br>Datum: do, sep. 20, 2012 11:13<br>Onderwerp: [Inkscape-devel] Inkscape 0.49 Proposed Release Plan<br>Aan: &quot;Josh Andler&quot; &lt;scislac@...400...&gt;<br>CC: &quot;Johan Engelen&quot; &lt;jbc.engelen@...2592...&gt;, &quot;Inkscape Devel List&quot; &lt;inkscape-devel@lists.sourceforge.net&gt;<br><br><br>2012/9/19 Josh Andler &lt;scislac@...400...&gt;:<br>&gt; I think that if we are going to break compatibility, we go for one<br>&gt; release to do it. Basically, all of the new-style stuff including<br>&gt; custom doc coords would be a huge win to introduce all at once. I<br>&gt; would love to see a rotatable canvas in Inkscape, but I have no idea<br>&gt; how feasible it is with the current rendering/viewport stuff we have<br>&gt; in place.<br><br>In principle it should be possible to change doc2dt and dt2doc<br>matrices to any transform without any modifications to the display<br>subsystem, but it might expose bugs - mainly hidden assumptions that<br>doc2dt is always an Y flip + translation.<br><br>The code drawing the page background will need to be rewritten, as it<br>now assumes that the page is a rectangle with sides parallel to<br>desktop coordinate system axes.<br><br>Regards, Krzysztof<br><br><br>
