26. Graphic editing tools

26.1. Introduction

To create and edit various types of vector data with some feature formats. Other formats are read-only and don´t allow editing.

To add or modify elements of one layer, it requires that the layer is active and in editing mode. Depending on the layer type the options will be different.

These tools are available from “Layer” menu and “Remove”, “Insert” and “Modify” submenus, from the “Edit” menu and from the specific button bar.

26.3. Command console

26.4. Flatness

In gvSIG any curved geometry is made up of one determined number of sections. Flatness is the parameter to define the density of the straight lines which define the curved geometries. A high Flatness number can make that the curved elements will be visualized as polylines.

In “Preferences/Flatness”, its value can be modified.
