Description arturrataj 2014-05-06 10:29:35 UTC

Brush outline shortcuts two of the segments of the otline with a single segment. So a single pixel brush has the outline of a triangle, etc. Also, when not in OpenGL mode, it seems that the common point of two adjacent segments is invisible, probably due to double negation. It gives poor visibility if the canvas zoom is not high.


Reproducible: Always

Steps to Reproduce:
1. Choose a brush with a known, simple shape.
2. If not in OpenGL mode, the outline behaves strangely and has visibility problems.
2. Zoom--in the canvas, until pixels are visible as clear rectangles.
3. See the shortcutted segments.


Expected Results:  
Outline having the exact shape of the brush, and no double color negation.

Yes, I can confirm the little triangle effect.

Comment 2 Dmitry Kazakov 2014-05-07 17:29:08 UTC

I have fixed the bug today locally, now I just need a bit of cleanup.

Fix a triangular brush outline for a 1px brush

This patch also fixes major code duplications in the
KisOutlineGenerator. Now everything is templated.
