    3. Transparency (from 0 to 100%)
    4. Line width in points
    5. Definition of visibility scale,
  3. Polygon layer

Manager’s description

  1. Style tab
    1. Left section – this is where you select the type of symbolisation and set its parameters
    2. Right section – this is where you set the basic settings depending on the type of geometry (point, line or polygon)
      1. Labelling management
      2. In addition, you can export and import the style
  2. Symbols tab – here you will find a library of SVG or PNG symbols which can be used to symbolise points. Tools
    1. Import icon – tools allow you to import an icon in SVG or PNG format (64x64px in size)

  2. Setting a unique style
  3. Setting a progressive style
  4. Setting the object label style
