WxGUI Vector Digitizer

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 and optionally centroid(s) with category defining new area(s). 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(s) which define the newly created area(s).

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 area and define it's attributes

Modifying linear features

Add new vertex

Places new vertex to the linear feature (line or boundary).

Mouse buttons functionality:

• Left
  • Place new vertex in given select threshold
• Right
  • Rewrite line with newly added vertex
• Control+Left
  • Undo (do not add new vertex)
