Dialog box “Transforming the boundary to circle”

Purpose and description

The dialog box allows specifying parameters of the polygon modeling the circle when performing the operation of transforming a boundary of an area or an image feature to a circle.

The input field Center contains coordinates X and Y of the circle center in map coordinate system. By default the system offers an arithmetic average of all vertices of the source polygon.

The input field Radius contains the circle radius (in map units). By default the system offers an arithmetic average of distances of all vertices from the calculated center of the circle.

The input field Number of points contains the number of vertices of a regular polygon modeling the circle. By default the system offers to use 36 vertices.
