Contour

Ribbon: Raster– Filters> 4 Connected Contour

Ribbon: Raster– Filters> 8 Connected Contour

Menu: Raster – Filters – Contour > 4-coupling

Menu: Raster – Filters – Contour > 8-coupling

Command line: CONTOUR4

Command line: CONTOUR8

This functionality is available only in the Raster module.

Contour filters turn filled raster areas into single-pixel contours. In a four-connected contour, adjacent pixels can only be joined by the sides, in an eight-connected contour, contiguity is also allowed at the corners, so such contours look thinner.
The images below show the results of applying contour filters.

Parts of contours obtained with four-connected and eight-connected filtering

Select the images to be processed and run the command.
