New map layerEach map project in L3DT usually has a number of map layers, such as the design map, heightfield, water map, etc. With custom scripts or plugins, you may also wish to add custom map layers (e.g., as a mask for a plugin calculation). The 'Layers→New map layer' menu option allows you to do just this. The control window is shown below: Map nameL3DT stores and accesses maps based on a name, which you may set in the 'map name' text field. This name must have a non-zero length, and cannot match the name of an existing map layer. You may use spaces in the name, but you may not use the following characters:
The following map names are reserved by L3DT, and may not be used:
Map typeAt present, L3DT allows the following custom map layers:
Map sizeUsing the map size text fields, you may enter the desired number of pixels in the map. The constrains on maximum map sizes are as follows:
There are no constraints on aspect ratios. Mosaic optionsSplit map into tilesThis check box determines whether the map will be tiled as a mosaic map, or will be stored as a single file. This option also determines the maximum allowable size of the map (see above), as tiling enables memory caching. Tile sizeThe size-length, in pixels, of each individual tile in the mosaic map. 512 is default. Larger values may increase calculation speed, but also increase RAM usage. File formatMosaic maps are automatically saved/loaded from disk. Before this can happen, you must select the file format to be used from the file format drop-list. The list of file formats is determined by the chosen map type, and the file format plugins that are installed. Other settingsYou may be wondering why you cannot in this window set the horizontal scale, wrap flag, or other map settings that are available in the algorithm wizards (e.g. heightfield size, fractal parameters, etc.) The reason is that these settings are inherited from the project:
Thus, you cannot independently set the horizontal scale of a map layer, or have a wrap flag for a map layer that is different from the rest of the maps in the project. Except where otherwise noted, content on this wiki is licensed under the following license:CC Attribution-Share Alike 3.0 Unported
