Raster map domain Class |
|
Specify display options for a raster map with a class domain or a group domain.
Before a map is displayed in a map window, you have to answer some questions on how this layer should be displayed in the map window. Also, once a map is displayed in a map window, you may want to change the display options of a certain layer:
Dialog box options:
Info: |
Select this check box if you want to see the class names of pixels when you press the left mouse button in a map window. Clear this check box if you do not want to see class names. |
Scale limits: |
Select this check box when this map should be displayed or hidden depending on the scale specified in the scale control of the map window; specify the scale range within which the map should be displayed. The map will be automatically hidden if the scale of the map window is outside this range. With this option you can achieve for instance, that very detailed maps (e.g. on cadastral units) are only displayed when using a large scale in a map window, or that very general maps which depict overviews are only displayed when using a small scales in a map window, etc. Clear this check box when you wish to display the map regardless of the scale of the map window. |
Transparent: |
Select this check box when you wish to display this raster layer with a certain transparency. Any layer that has been added to the map window before, e.g. an image or a shadow map, will remain partly visible through the transparent raster layer. Subsequently, type a value for the transparency rate (percentage): value 1 means almost not transparent, and value 99 means almost totally transparent. Clear this check box to just display the layer, i.e. non-transparent. Mind:

Text: |
Select this check box if you want to see the class names of pixels displayed as text on top of the pixels. Subsequently, select a color for the text from the appearing Text Color list box. Clear this check box if you just want to see the map. |
Attribute: |
Select this check box if you want to display the map by an attribute column found in the attribute table linked to this map. Subsequently, select a column from the attribute table and select a representation for the classes, IDs or values of that column. Clear this check box if you want to display the class map itself. |
Representation: |
Select a user-defined representation class for this map, or create a new representation with the Representation Class editor. In case you display this class map by a value attribute column, and you click the create representation button, the Representation Value/Gradual editor is opened. |
|
Select option Light to display this map a little lighter than normal, select option Normal to display this map with normal brightness, or select option Dark to display this map a little darker than normal. Select option Gray to display this map in gray tones regardless of the selected representation. |
Create Pyramid Layers: |

In case pyramid layers are not yet available for this raster map:
For more information on pyramid layers, see ILWIS objects : Raster maps - Pyramid layers. |
The first text line in this dialog box states the map type and the map name. Furthermore, the dialog box shows the description and domain of the map.
For more information on representations, see How to use representations.
