Supported file formats for background images
Vissim supports the following file formats for graphic files:
| Raster formats | |
|---|---|
| *.bmp | Windows bitmap, two-dimensional | 
| *.jpg | graphic compressed according to JPEG (Joint Photographic Experts Group) standard | 
| *.png | Portable Network Graphics, compressed with no loss in quality | 
| *.tga | Targa (Truevision Advanced Raster Graphics Array) image file, uncompressed or compressed with no loss in quality. Also saves values for alpha channel, gamma correction and text as meta-information. | 
| *.tif | Tagged Image File Format, uncompressed or packbits compressed | 
| *.sid | Mr. SID files, display with best possible resolution | 
| *.ecw | Enhanced Compressed Wavelet, for large raster graphics, e.g. aerial images. The *.ecw file format provides the following advantages: 
 Compression rates recommended for Vissim: 
 | 
| Vector formats | |
|---|---|
| *.dwg | Is updated for each new version of Autodesk AutoCADTM | 
| *.dxf | Is updated for each new version of Autodesk AutoCADTM | 
| *.emf | Windows Enhanced Metafile | 
| *.wmf | Windows Metafile | 
| *.shp | Shapefile for spatial data Vissim supports transparency in 2D mode and 3D mode. | 
| Document format | |

- The 64-bit edition of Vissim supports the file formats of *.dwg versions up to DWG2013.
- AutoCAD saves the current layout with the position, translation vector and rotation with a *.dwg or *.dxf file, if the file is saved in AutoCAD.
- These layout settings are taken into consideration by Vissim as much as possible for the display of a loaded background image.
- The import of pedestrian areas and obstacles of a *.dwg file do not take these layout settings into consideration for the graphic display.
- When you save a *.dwg or *.dxf file in AutoCAD, ensure that the current layout settings are suitable for use of the file as a background image in Vissim. This applies, in particular, before loading a *.dwg file as a background image, after construction elements for pedestrians have already been imported from this file in Vissim.
