This page covers core functionality of wxGUI vector digitizer and also explains it's usage for newcomers.

Adding new features

Point

Mouse buttons functionality:

  • Left
    • Add new point on given position
wxGUI vector digitizer - add new point and define it's attributes

Line

Mouse buttons functionality:

  • Left
    • Add new vertex on given position
  • Right
    • Write out the new line with given number of vertices
  • Control+Left
    • Remove last added vertex from the line
wxGUI vector digitizer - add new line and define it's attributes

Boundary

Mouse buttons functionality:

  • Left
    • Add new vertex on given position
  • Right
    • Write out the new boundary with given number of vertices
  • Control+Left
    • Remove last added vertex from the boundary
wxGUI vector digitizer - add new boundary and define it's attributes

Centroid

Mouse buttons functionality:

  • Left
    • Add new centroid on given position
wxGUI vector digitizer - add new centroid and define it's attributes

Area

This functionality combines adding new boundary without category. If the newly added boundary defines an area or two areas on the left and right from the boundary it will also add new centroid which define the newly created areas.
