BMP Exporter    BMP Inflator    BMP Calculator

The Windows BMP export plugin exports an 8 bit greyscale uncompressed BMP image. This is an easy way for you to be able to edit terrains in a paint program/image editor such as Photoshop, Paintshop Pro or Graphic Converter. As the image size is included in the file, it's a much more user friendly option than using Terragen's 8 bit RAW export.

When used in conjunction with the BMP Inflator plugin, you can easily export and reopen a BMP image many times and still keep the correct proportions of the terrain.

Despite the name of the plugin, it's possible to use this plugin on the Mac as well, if you have an image editor that can open BMPs. Photoshop does it nicely.

The Interface

Mac version	Windows version

The BMP export plugin is easy to use. Here's a guide to it's settings :

• Units radio buttons
  These two radio buttons let you choose between using Metres or TG Units for measurements, where appropriate.
  

• Base Height
  This displays the base height of the terrain, or lowest point, before it is exported. This setting is recorded in the FEB file ( described below ), or if you choose not to use that you should take a note of this value to enter in the BMP Inflator when you want to bring the BMP back into Terragen. If you use the FEB file, or manually enter this number into the Base Height setting of the BMP Inflator, then it will be able to recreate the terrain starting from the same height as the original, so that all your water and surface map settings etc. will still be correct.
  

• Scale Factor
  This displays the scale factor that the plugin uses when creating the BMP image. This setting is recorded in the FEB file ( described below ) if you choose to use it. Otherwise you will need to take a note of it if you wish to bring the BMP back into TG using BMP Inflator. If you use the FEB file, or enter the number manually in the Scale Factor field of the BMP Inflator, the terrain will retain the same proportions as when you exported it.
  

• Point Spacing
  This displays the point spacing used for the terrain you're exporting. The point spacing is recorded in the FEB file ( described below ) if you choose to use it. Otherwise you will need to take a note of this value and enter it in the BMP Inflator when you want to bring the image back into Terragen.
  

• Use .FEB file
  If this option is checked, an FEB file is created. The FEB file records the Base Height, Scale Factor and Point Spacing. The file will have the same name as the exported BMP file, but with a .FEB extension. When you use the BMP Inflator to bring a BMP back into Terragen it looks for an appropriate FEB file to load the initial settings from. This saves you having to take a note of the aforementioned values and enter them manually in the BMP Inflator. If you rename the BMP file before bringing it back into Terragen, you should also rename the FEB file to match or it won't be loaded. FEO does not delete FEB files after using them.
  

  The FEB file is an XML formatted text file.
  

• Cancel button
  This button closes the plugin window without recording the changes you've made to the settings.
  

• OK button
  This button closes the plugin window, records the changes you've made to the settings and brings up an Save File dialog box.
  

Requirements

For Export Only needs the TGPGuiLib to run. This file provides cross platform interface functionality. To find out more about the TGPGuiLib and download the latest version, visit it's website.
