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

Adding new features

Point

Point-create.png

Mouse buttons functionality:

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

Line

Line-create.png

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

Boundary-create.png

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

Polygon-create.png

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

This functionality covers linear features (lines and boundaries).

Vertex

Add

Vertex-create.png

Add new vertex to the linear feature (line or boundary). This operation won't change the shape of the selected feature.

Mouse buttons functionality:

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

wxGUI vector digitizer - place new vertex to the linear feature

Remove

Vertex-delete.png

Remove selected vertex from the linear feature (line or boundary). This operation will change the shape of the selected feature.

Mouse buttons functionality:

  • Left
    • Select vertex to be removed in given select threshold
  • Right
    • Remove vertex, rewrite the feature
  • Control+Left
    • Undo (do not remove vertex)
