8.12.2 Convolver Options
Convolve Settings
Opacity The Opacity slider sets the transparency level for the operation. A higher
opacity setting results in a more opaque render and a lower setting results in a
more transparent one.
Pressure Sensitivity The Pressure Sensitivity section sets whether hardness, rate
or size will be effected by pressure for input devices that support this option.
Rate The rate slider sets the strength of the convolve effect.
Convolve Type • Blur mode blurs the image colors into each other. The result will
be a smooth transition between colors, but will always be darker than the
original colors.
• Sharpen mode causes neighboring pixels with similar colors to converge.
Used judiciously, blurry edges can be sharpened somewhat, but if applied
repeatedly it can produce unusual results.
