Info:
Select this check box if you want to see the color values for Red, Green and Blue when you press the left mouse button in a map window. Clear this check box if you do not want to see color 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 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:
- For Transparency, the Display Settings of your screen must be set to 32 bit (True Color).
- When the map window already displays another raster map, you can only add raster maps which have the same georeference. You can use the Resample operation to transform a raster map to a desired georeference.
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 to display this map in gray tones regardless of the colors in the picture.
Create Pyramid Layers:
In case pyramid layers are not yet available for this raster map:
- Select this check box to create pyramid layers for this raster map. Pyramid layers speed up the display of large raster maps in a map window.
- Clear this check box if you do not wish to create pyramid layers for this raster map.
For more information on pyramid layers, see ILWIS objects : Raster maps - Pyramid layers.
