Supported file formats for background graphics

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: high compression rates visually flawless image quality Contrary to other file formats, it does not cause any noteworthy delays while navigating in the Vissim network. Compression rates recommended for Vissim: 9:1 for high quality 20:1 for good quality with shorter loading time

Vector formats
*.dwg	Is updated for each new version of Autodesk AutoCAD^TM
*.dxf	Is updated for each new version of Autodesk AutoCAD^TM
*.emf	Windows Enhanced Metafile
*.wmf	Windows Metafile
*.shp	Shapefile for geodata

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 graphic.
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 graphic in Vissim. This applies, in particular, before loading a *.dwg file as a background graphic, after construction elements for pedestrians have already been imported from this file in Vissim.
