Size – brush size
Opacity – transparency of every brush stamp/point
Transparency – transparency of whole brush stroke
Color amount – amount of the main color at the mix
Blur – blur of mix
Extends color – option fixes how long mixed color follows the brush
Stabilizer – amount of stroke stabilization
Opacity vs Transparency
Mixing/blending colors
To get some color blend color amount should be less than 100%. The color amount less, the more blending.
Take under checkbutton – pick up colors from bottom layers.
Blend Transp. check button – mixing channel of transparency (does not work for bristle brushes. Can not be turned on with option «Take underlayers color».
Extends color(extension) If you set it on 100 – color will follow forever. Recommended amount for the simple brush is from 0 to 90, and for bristle brush from 40 to 90.
Option depends on Color amount set. If you don not use option “Color amount”, “extends color” does not take an effect.
Blur effect:
With blur = 100(default) mixed color is an average color of all colors inside brush form
With less blur – colors mixing with nearest points
With blur = 0(zero) – colors do not mix, but it’s adding to the color table of mix
Example with simple round brush with spacing 0 (fixation):
- Blur = 70 ; Color amount = 10 ; Extend color = 70; This is medium parameters gives a little main color (red) blended with background for some distance
- Blur = 70; Color amount = 0; Extend color = 70; Same as (1) but with zero color amount works as a “finger”
- Blur = 0; Color amount = 0; Extend color = 100; Infinity expansion for every pixel
- Blur = 0; Color amount = 0; Extend color = 0; Blured with nearest pixels without any expansion
- Blur = 90; Color amount = 0; Extend color = 100; Blured and extened to infinity distance
Stabilizer
Stabilizer is the delay between drawing of dash and movement of brush. It is used for drawing straight lines
Also, you can enable rope and spring checkbox for super accuracy lines.
