See the Brush Tools Overview for a description of tool options that apply to many or all brush tools.
Convolve Type Blur mode causes each pixel affected by the brush to be blended with neighboring pixels, thereby increasing
the similarity of pixels inside the brushstroke area. Sharpen mode causes each pixel to become more different from its
neighbors than it previously was: it increases contrast inside the brushstroke area. Too much Sharpen ends in an ugly
flocculation aspect. Whatever setting you choose here, you can reverse it on-the-fly by holding down the Ctrl key.
I slør-modus blir kvar piksel som blir rørt av penselen blanda med dei nærliggande pikslane og gir såleis ei overvekt
av nokså like pikslar i penselstrøket. Dette gjer at overgangen mellom fargane blir viska ut, men kan også føre til at
overgangen blir mørkare.
I skjerp-modus blir kvar piksel litt meir ulik nabopikslane for kvart strøk. Kontrasten aukar. Held du for lenge, kan
resultatet bli uventa stygt.
Same kva innstilling du vel, kan du bytte rundt valet ved hjelp av Ctrl-tasten.
Rate The Rate slider sets the strength of the convolve effect.
