3dbox shapes are corrupted when page size is changed

[groendraakie]

After drawing a view 3d boxes on a A4 page size drawing and changing the page from portrait to landscape, the 3d boxes are corrupted and unrecognizable.
Their positions do not match with the handles, etc.

the version of inkscape I use is Inkscape 0.45+0.46pre0+devel, built Jan 15 2008
screenshots will be added. With this comment it is the "before"-screen

Confirmed on SVN rev 17209 (Jan 30) under Linux. 3D box is also corrupted by using 'fit page to selection', or changing the paper size.

Thanks for reporting this. However, this is not restricted to 3D boxes. It happens with all kinds of objects. Just draw a simple rectangle or ellipse and use "fit page to selection" or any other method as described above. The handles will always be off and the shapes are sometimes screwed up.

A quick glance seems to suggest that this is yet another occurrence of the annoying mixture-of-coordinate-systems bug in Inkscape (desktop vs. item coordinates). Something about the item coordinates or the transform matrix probably doesn't get updated when the page size changes. Also note that it only goes wrong when the page _height_ is changed; setting the page width doesn't have a malicious effect.

I unassigned this bug from myself and changed the caption because it is not specifically 3D box related. But I'll keep an eye on it and fix it if I find the cause. If anyone else is faster than me, please go ahead (my time is severely limited during the next 2-3 weeks).

purely cosmetic, no data corruption, so low priority

[Tom Davidson (tjd-mit)]

Actually, no.

1) draw a 3d Box in the middle of the page
2) 'fit page to selection' -->box is drawn correctly in the new page, but the control nodes are elsewhere
3) save to tmp.svg
4) close inkscape and reopen tmp.svg
5) 3D box appears outside the page, and the control handles still appear back in the location corresponding to the box (see screenshot)

I.e. Not just a redraw error, as it survives restarting of inkscape, as with the Rectangle error. Perhaps this is 3D box related, after all?

[Tom Davidson (tjd-mit)]

Re-assigning to Maximilian Albert:
While there is a problem for all shapes where node handles are not redrawn on resize, that problem is just cosmetic, and can be fixed by just clicking on the object, or switching tools (probably this should be a separate bug). 3Dbox objects, however are actually corrupted. You can verify this by saving and reopening the file--the 3dbox node handles are in the wrong place, and the selection bounding box is also out of place (see the latest screenshot)

[Tom Davidson (tjd-mit)]

This looks very very similar to the bug seen in behavior of 3d box objects when they are part of a group (bug 188991)...

It seems that in both cases, the objects are getting transformed, but the control handles are not. In both cases, if you trigger the bug, then go move the control handles, the 3dbox jumps back to its location before the transform or page resize...

[Tom Davidson (tjd-mit)]

(The issue of node handles not being redrawn correctly for objects other than 3d boxes upon page resize is at bug 179373 )

take a look at this jing
a real bug

I am on VISTA and using INK .46

I think that there's something real going on. For example, guides get moved differently from objects. So an object that is originally aligned with guides is no longer so aligned after resizing the document. See attachment.

The issues with Portrait->Landscape and changing paper sizes are now fixed (bzr rev. 8911). There is still a glitch when using "Fit page to selection" but this should be covered in a different bug report.
