            Bug ID: 90868
           Summary: EDITING: Interactive image crop tool can't apply
                    proportional crop
           Product: LibreOffice
           Version: 4.4.0.3 release
          Hardware: Other
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Draw
          Assignee: libreoffice-bugs@lists.freedesktop.org
          Reporter: tmac...@gmail.com

Description:
The new interactive crop tool in Draw/Impress in 4.4 has no way to perform an
proportionally constrained crop.  This is useful if you want to keep your
image's aspect ratio while cropping off the sides.  This action would normally
be performed by holding down shift while dragging your crop region.

Bug 86329 fixed the preview rectangle overlay that appears while you drag your
crop region.  With that bug fixed (merged in master and should hopefully be in
4.4.4), this preview behaves properly and constrains proportions when you hold
shift.  Unfortunately, the resulting crop when you release your drag does not
behave properly, and ends up wherever you release (not constrained).

Steps to reproduce:
1. New drawing
2. Insert image
3. Right click image and Crop Image
4. Hold shift key and drag a crop region *
5. Note results of attempted constrained crop

* Again note that if testing in versions before bug 86329's fix, the crop drag
preview overlay (rectangle while actually dragging) had its behavior reversed,
which scaled proportionally by default and holding shift caused it to not
constrain.

Expected:
If holding shift while dragging out and releasing crop region, the resulting
selection should be constrained.

Actual:
Resulting crop completely ignores the shift key and selects an unconstrained
crop region.

Notes:
As far as I know, there is currently NO way perform an accurate constrained
crop in Draw/Impress in LO 4.4+.  You completely have to eyeball it.  Before,
you could at least use math to figure it out.

I find constrained crop to be VERY handy.  If I have many images on a page, I
usually want to keep them all 3:2 or 4:3 or whatever.  This bug really hampers
my ability to use LO's built in crop tool.  It will affect me much more if/when
this tool is implemented in Writer.
