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.
