Bug ID: 456134
Summary: Wishlist- Resizing of Transform Masks (Animated and
non-Animated) should be optional
Product: krita
Version: nightly build (please specify the git hash!)
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Animation
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
The 'fix' of https://bugs.kde.org/show_bug.cgi?id=455349 has bad consequences
for some types of work with animated transform masks. It makes resizing very
slow.
This fix is:
https://invent.kde.org/graphics/krita/commit/ea817fb6418c4866712ac88288113f8b6d2d3b3e
These consequences will be demonstrated in this Wishlist bug report by use of a
demonstration file that can be downloaded from:
https://www.dropbox.com/s/brar1d1vx7in4li/Reveal-Generator-Demo.kra?dl=1 (19MB
download).
The resizing of the transform masks should be an on/off option selectable by
the user.
Personally, I'd be happy with a flag value in kritarc but a GUI Settings option
may be preferred by some.
STEPS TO REPRODUCE
1. Download the Reveal-Generator-Demo.kra file (Dropbox link above).
2. Use version 5.0.6 to open it (before the change was made).
3. Play the animation just to see it.
4. Turn off the visibility of the 'Horizontal Thin Wedge R>L' animated
transform mask - this is colour coded as blue.
5. Note that there are many different animated transform masks, any one of
which can be selected (made visible) to create different animated effects,
depending of which one of a few shapes from the 'All Shapes' group is selected
(made visible). Please don't try that unless/until you're fully familiar with
the file.
6. Do Image -> Resize Canvas to a new size of 5,760 x 4,320 pixels.
7. Note that this reveals a lot of previously off-canvas content. Imagine
yourself editing this content or creating new off-canvas content.
8. Do Image -> Resize Canvas to the original size of 1920 x 1080 pixels.
9. Turn on the visibility of the 'Horizontal Thin Wedge R>L' animated transform
mask - i.e back to normal use.
10. Play the animation and note that all is back to normal.
11. Quit with no saving.
12. Use version 5.1.0-beta1 or a later prealpha version to open it (after the
change was made).
13. Repeat Steps 3. to 5.
14. Repeat step 6.
OBSERVED RESULT
6. This happens in a short time and reveals the previously off-canvas content.
14. See how long you are prepared to wait until the Resize operation is
complete. I lasted for 3 minutes until I gave up and killed the appimage.
EXPECTED RESULT
An option to disable resizing of transform masks would be essential to work
with this and similar .kra files.
SOFTWARE/OS VERSIONS
Appimages using Debian 10 MATE on an old desktop PC.
