            Bug ID: 134665
           Summary: Miscalculation of size of a shape/object in Animation
                    : Emphasis - Grow and Shrink
           Product: LibreOffice
           Version: 6.4.2.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
when we draw any shape object like rectangle or circle and animate it using
"Grow and Shrink" effect of Emphasis category, impress seems to miscalculate
the resulting size of the shape.
it can be easily observed by choosing animate size 101%.
I believe the shape should grow 1% to become 101% of its original size, but it
grows 101% to become 201% of its original size.

It is a miscalculation because when we animate the shape size  90% (enter the
size value 90%), the shape reduces to 90% of its original size by reducing its
size by 10%.

Steps to Reproduce:
1. Add any Object (rectangle or circle)
2. Choose Animation Category : Emphasis - Effect : Grow and Shrink
3. Choose a value 101%

Actual Results:
object size grows to 201% (increase in 101%)

Expected Results:
object size should grow to 101% (should increase only 1%)


Reproducible: Always
