Description
Created attachment 348726 spreadsheet result with paint tools (paintbrush, pencil, airbrush and smudge).
The paint tools are presenting problems with Fade Options. See attachment 'fade-options-status-and-bugs.ods'. All tests are made with same brush and a default dynamic curve (linear). All are executed on GIMP Git Master 2.9.5 commit 10360c9e Ubuntu Gnome 14.04.2 - GNOME 3.10
Assets used
- Round dark brush, Flat dark brush;
- Paint dynamic to set the fade with each output.
Main setup on Tool Options
- Size brush fixed in 25px
- Hardness 100
- Force 50
- Jitter 2
- Rate max
- Flow max
Paint tools with problems are the Paintbrush, Pencil, Airbrush and the Smudge. I didn't have time to test all paint tools, but is probable that issues are the same... but in the next days I will verify the paint tools not mentioned yet in this bug report.
In short the main issues are:
-
Hardness x Fade (all tools): apparently the curve is applied, but with strange artifacts... The process presents delay. See attachment 'hardness-issues_fade.jpg'.
-
Rate x Fade | Airbrush: apparently the Rate is not working, with a linear paint dynamics doesn't produces any variation. The behavior when you change Fade lenght and/or Repeat type is always the same or seems. Are welcome tips for me test this tool. See attachment 'rate-issues-airbrush_fade.jpg'.
-
Rate x Fade | Smudge: is 'working incorrectly' only with 'Reverse' option. The linear curve and fade length are not applied. See attachments 'rate-issues-smudge-1_fade.jpg' and 'rate-issues-smudge-2_fade.jpg.
