           Summary: Using a shape mask with a bitmap Shapes | Subtract
                    alters aspect ratio of bitmap
           Product: LibreOffice
           Version: 6.4.3.2 release
          Hardware: All
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Draw
          Assignee: libreoffice-bugs at lists.freedesktop.org

File showing an expression of the issue in a real example.

When you make a mask to subtract areas from a bitmap, after applying the mask
using right click, Shapes | Subtract, the resulting image has its aspect ratio
altered. 

REPLICATION:

1. Create a new page
2. Add a bit map image to the page
3. Add a rectangle shape to cover the image
4. Add a shape above the rectangle (e.g, circle or hexagon)
5. Use the Shapes | Subtract to remove the hexagon from the rectangle
6. Then use the resulting shape with a hexagonal hole to create a hexagon crop
of the image
7. Observe the aspect ratio has changed

EXPECTED:
The area of the image to which the mask was applied should remain the same, as
should the size.

IMPRESS NOT AFFECTED:
Note that this only occurs in Draw. In Impress, the mask behaves as expected.
