Specifies the background color used when creating the raster image file.
The Autodesk Raster driver supports the following raster file formats:
- Uncompressed BMP
- Uncompressed TGA
- PCX - Zsoft packbits format
- Uncompressed TIFF
- Group 4 2D compressed bitonal TIFF
- CALS MIL-R-28002A Type 1 (CCITT G4 2D Compression)
- Dimensional CALS Type 1 (CCITT G4 2D Compression)
- JFIF - JPEG compressed
- PNG 1.0
Specify the file format on the Plotter Model page in the Add-a-Plotter wizard.
The Media node in the Plotter Configuration Editor provides a range of bitmap sizes for the raster driver. All of these sizes are plotted with an aspect ratio of 1:1. Some of the file formats offer a choice of color or monochrome and a choice of color depths (for example, 2 shades of gray, 256 colors, and so on). To specify graphics settings, choose the Graphics node in the Plotter Configuration Editor and select Vector Graphics.
The following table shows the supported raster file formats, the available color depth options, and the file extension of the relevant output file. In the Color Depth column, indexed is 8-bit, 256 colors, RGB is 24-bit True Color, and RGBA is 32-bit True Color.
Supported raster file formats

| Uncompressed BMP | Bitonal, grayscale, indexed, RGB | .bmp |
| Uncompressed TGA | Indexed, grayscale, RGB, RGBA | .tga |
| PCX - Zsoft packbits | Indexed, RGB | .pcx |
| Uncompressed TIFF | Bitonal, indexed, grayscale, RGB, RGBA | .tif |
| TIFF - Group 4 Two-dimensional Bitonal Compression | Bitonal, indexed, grayscale, RGB, RGBA | .tif |

| JFIF 5.0 - JPEG | Gray, RGB | .jpg |
| PNG 1.0 | Bitonal, grayscale, indexed, RGB, RGBA | .png |
BMP files are Microsoft Windows bitmap files. These files can be created in and read by Windows Paint; all Windows applications can import them.
