Info:
Select this check box if you wish to see the class name, ID, or value of a polygon when you press the left mouse button on a polygon in a map window. Clear this check box if you do not wish to see information on polygon class names, IDs or values.
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 polygon 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 polygon 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: For Transparency, the Display Settings of your screen must be set to 32 bit (True Color).
Mask:
Select this check box when you only wish to display polygons with specific class name (s), identifier(s) or value(s). Subsequently, specify the mask, i.e. the class names, IDs or values of the polygons that you wish to display. For more information, see How to use masks. Clear this check box when you wish to display all polygons of this polygon map.
Boundaries only:
Select this check box if you only wish to display the boundaries of the polygons. Clear this check box if you wish to display the polygons themselves (hatched or in color) and the polygon boundaries.
Hide superfluous boundaries:
Select this check box if you wish to display only polygon boundaries that separate polygons with different names or values. When using the Attribute option, only boundaries that separate of areas with different attributes will be shown.
Clear this check box if you wish to display all polygon boundaries.
Boundary color:
Select a color for the polygon boundaries from the list box. To create your own color, select Custom at the bottom of the drop-down list, or click the create button.
Boundary width:
Specify a line width for the polygon boundaries. When you specify a boundary width of 0, no polygon boundaries are shown. Line width is expressed in screen pixels.
Attribute:
In case of Class and ID maps with an attribute table linked to the map or its domain:
Select this check box if you wish to display the map by an attribute column found in the attribute table. Subsequently, select an attribute column from the attribute table and select a representation for the classes, identifiers or values of that column. Clear this check box if you wish to display the map itself.
Representation:
This option is available for maps using a class or a value domain.
In case of a class map: Select a user-defined representation class for this map, or create a new representation with the Representation Class editor. A representation class for polygons contains colors and patterns (hatching).
In case of a value map: Select a system representation or a user-defined representation Value/Gradual for the map or create a new representation with the Representation Value/Gradual editor. By creating a new representation, you can 'classify' the map. A representation value/gradual contains colors.
Single color:
Select option Single color if you wish to display all polygons in the same color. Subsequently, select a color from the appearing list box. To create your own color, select Custom at the bottom of the drop-down list, or click the create button. Tip: The default color can be set in the Preferences, section Map window, Display (color selected for True in Bool maps).
Multiple colors:
For maps using an identifier domain: Select option Multiple colors if you wish to display the polygons of the map in 7, 15, or 31 different colors or in random colors.
Stretch:
For value maps with a representation gradual: Specify the stretch range. When a histogram is available of the map, the 1% interval values are given as default stretch range, else the 0% interval values are given as the default stretch range.
Light, etc:
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 if you wish to see the map displayed in gray tones regardless of previously selected colors.
