Representation Class editor

Functionality

With the representation class editor, you can change the representation as used by a class domain, a group domain, or a picture domain. In the representation class editor, you see all the class names of the domain to which this representation is linked, and the way in which these classes will be represented on the screen and on a printer.

For each class as available in the domain, you can edit:

The Representation Class editor consists of an editor window with the class names and their colors, a menu bar, a toolbar, and Red, Green and Blue color slide bars at the bottom of the window.

To start the Representation Class editor, see How to create a representation and How to edit a representation.

Tip:

You can always create a number of representations for a certain domain, for instance by clicking the create button next to the Representation list box in the Display Options dialog box of a map. Then, to display a map with a certain representation, in the map's Display Options dialog box, select the representation you want to use.

General working of the Representation Class editor:

  1. Select a map type:
  2.    

    Keep in mind that when changing a color of a class in one 'mode' (e.g. Polygon), then the color of this class will also change for all other modes (e.g. Raster, Segment).

       

  3. Select a single class in the editor window and subsequently edit the color and optionally other representation attributes of this class:
  4. The Edit Repr Item (raster), Edit Repr Item (polygon), Edit Repr Item (segment) or the Edit Repr Item (point) dialog box will appear.

       

    Depending on whether you selected to edit the raster form, polygon form, segment form or point form of the representation, the Edit Repr. Item dialog box will allow you to edit:

       

    Furthermore, you can use the Red, Green and Blue color slide bars at the bottom of the editor window to edit the colors of a single selected class.

       

  5. Select multiple classes in the editor window and subsequently assign a single color to all selected classes or assign a smooth range of colors to the selected classes.
  6. The Edit Multiple Items dialog box will appear.

       

    Assigning a range of colors can be used:

    When assigning a color range, the order of the classes in the domain will be used. For more information, see the Edit Multiple Items dialog box.

To interactively change colors of maps:

  1. For any raster, polygon, segment or point map with a class or group domain:
  2. For more information, see Map window : advanced functionality.

       

  3. For any raster, polygon, segment or point map with a class, group or value domain:
  4. In this way, you can work with a representation editor and a map window simultaneously.

Tip:

Advanced users may wish to edit a representation class in table form; click a representation class with the right mouse button in the Catalog, and choose Open As Table from the context-sensitive menu.
