====== Importing a heightfield ======

Heightfields can be imported into L3DT using the '//File->Import->Heightfield...//' option in the menu.

At the time of writing((March 2009)), L3DT supports the following import formats:

  * '.bmp' - Windows / OS/2 compatible bitmap.
  * '.bt' - Virtual terrain project.
  * '.csv' - Comma Separated Value file.
  * '.hff' - L3DT (old).
  * '.hf2' / '.hfz' / '.hf2.gz' - L3DT.
  * '.jpg' - Joint Picture Experts Group image.
  * '.png' - Portable Network Graphic.

===== Importing from images =====

When importing from image files you will be asked to input some values, including the altitude range and the horizontal scale:

If you are importing a RAW image, you also need to set some import options using the '//Options...//' button (discussed next).

===== Importing from RAW files =====

Because [[l3dt:formats:specs:raw|raw binary data files]] contain, in general, no useful header information, you must specify additional information when importing a RAW, including the [[l3dt:formats:specs:raw#width and height]], [[l3dt:formats:specs:raw#mode]] (i.e. data type), and [[l3dt:formats:specs:raw#headersize|header size]] (if any). These settings may be reached by clicking on the '//Options...//' button in the above wizard.
