Bug ID: 438343
Summary: Animation curves - Transform Mask - Rotation not
intuitive
Product: krita
Version: nightly build (please specify the git hash!)
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Animation
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
More detailed information on krita-artist.org
https://krita-artists.org/t/krita-5-animation-curves-applied-to-transform-mask/24895/1#animation-curves-transform-mask-rotation-not-intuitive-13
STEPS TO REPRODUCE
1) Create a paint layer with a rectangle
2) Add a transform mask on paint layer
3) Create first keyframe at frame 0
4) Move to another frame (example, frame 15)
5) Select “Transform tool”
6) Do a counter-clockwise rotation (example -15°)
OBSERVED RESULT
By default, a counter clockwise rotation of 15° in Krita is equivalent to a
345° clockwise rotation.
Normally it’s not a problem.
But when tweening, result in not intuitive: the rotation is really a 345°
clockwise rotation.
We have to change value to -15°
EXPECTED RESULT
When working on an animation:
If user is doing a clockwise rotation to set angle, animation must be
clockwise
If user is doing a counter-clockwise rotation to set angle, animation must
be counter-clockwise
So finally:
- If user is doing a clockwise rotation, rotation value should be positive
- If user is doing a counter-clockwise rotation, rotation value should be
negative
Currently that’s really boring to have to calculate currentRotation - 360 each
time we need to set a counter-clockwise rotation.
It needs to be natural to user.
SOFTWARE/OS VERSIONS
Linux appimage krita-5.0.0-prealpha-dba5ce5-x86_64.appimage
ADDITIONAL INFORMATION
Maybe it's more an improvement than a bug, but for whom is used to work with
other software where tweening is available, the way Krita manage tje rotation
is not logical/intuitive
