Description Joachim Kreutzer 2021-10-22 09:04:17 UTC

Description:
If rotate any shape, the fill gradient doesn't affect the rotation. This is ok.

But, the rotation of the fill gradient can be forced when the shape is 'convertet to Meta'.

Since Version 7.0, this isn't working anymore.
But however, if you export the shape with pdf, or if you print it, the Rotation of the fill gradient is still be done.

Steps to Reproduce:
1. Draw an Rectangle
2. Choose fillstyle: axial, 0°
3. Convert to metafile
4. Rotate it, for example 30°



Actual Results:
Problem: the axial fillstyle stays at 0°.

This behavior ist new since Version 7.0

Expected Results:
The axial fillstyle should rotate by 30°.




Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
If you choose pdf-export, the fill style is rotated correctly by 30°!

This does not seem to be a regression as it behaves the same way in 3.3.0, 6.4 and the oldest of 7.0 bibisect repo (tested on Windows). Also seen on Linux. But I don't know if this is a limitation of the metafile format. Some developer could look into this.
