Opening files from the command line

L3DT can open a number of files from the command line. This occurs when:

You double-click on a file that is associated with L3DT (e.g. formats like HFF, PROJ, etc).
You drag a file onto the L3DT desktop icon or executable.
You use a command shell to open a file in L3DT (e.g. 'l3dt.exe myexample.bmp').

The following file types may be opened in this way:

File type	Extension	What happens?
Project file	proj, mgf	L3DT will open the map project.
Heightfield files	hff, ter, bt, etc…	L3DT will import the heightfield as a new map project. This works with all 'native' heightfield files.
Image files	bmp, png, jpg, etc…	L3DT will import the image as a heightfield in a new map project, but will first ask for import settings. This works with all 'non-native' heightfield formats. If not supported as a heightfield, the image will be loaded as a RGB texture.
Script files	zs, py	L3DT will run the script file (using ZeoScript for zs scripts, and cdPython for py scripts, if installed).
Map definition	def.xml	L3DT will create a new map based on the map definition.
Batch file	run	L3DT will create a set of maps based on the batch run file.
Plugin	zeo, dll	L3DT will install the plugin, after first asking you to confirm the action.
