Common Options of GEGL Filters

Presets

Filter presets are similar to tool presets, in that you can save your favorite settings and recall them when needed. They consist of:

  • A drop down list that shows the current preset and lets you choose a different one.

  • An icon to save the current settings as a named preset.

  • An icon that opens a menu with options to manage presets.

Input Type

The input type dropdown list is only visible when a selection is available.

  • Use the selection as input If this option is selected, the filter only uses pixels inside the selection as input for the filter.

  • Use the entire layer as input If this option is selected, the input of the filter is the entire layer. The output will only affect the selection. The layer outside the selection remains unchanged.

Blending Options

When you expand this option by clicking the +, you can choose the blend Mode to be used when applying the filter, and the Opacity. These work the same as the Layer Mode blending options.

Preview

When this option is enabled (default), changes in the filter settings are directly displayed on canvas. They are not applied to the image until you click the OK button.

Split view

When this option is enabled, the view of the image is divided in two parts. On the left side it shows the effect of the filter applied, and on the right side it shows the image without filter.

You can click-and-drag the line that divides the preview to move it, and Ctrl-click to make the line horizontal, or to switch it back to vertical.
