The Background Images list opens.
The list in the tab contains, amongst others, the following attributes:
| Column | Description |
|---|---|
| PathFilename | Path and filename of graphic file |
| CoordTRX | Coordinate top right (x): Coordinate (x) of the upper right corner of the graphic |
| CoordTRY | Coordinate top right (y): Coordinate (x) of the upper right corner of the graphic |
| CoordBLX | Coordinate bottom left (x): Coordinate (x) of the bottom left corner of the graphic |
| CoordBLY | Coordinate bottom left (y): Coordinate (x) of the bottom left corner of the graphic |
| CoordBLPt | Coordinates bottom left: Corner point CoordBLX and CoordBLY. When you change one value, the value associated with it in CoordTRPt is automatically changed as well. |
| CoordTRPt | Coordinates top right: Corner point CoordTRX and CoordTRY. When you change one value, the value associated with it in CoordBLPt is automatically changed as well. |
| Level | Name of level |
| ZOffset | Z offset: Height relative to the height of the level. Avoid values between -0.2 m and -0.5 m. |
| TileSizeHoriz |
Tile size horizontal: Width The background image is loaded tile by tile. Tiles are recommended for large networks with large background images. In 3D mode in particular, the duration for opening the graphic files depends on the file size of the graphics files. |
| TileSizeVert | Tile size vertical: Height |
| Res3D |
Maximum 3D resolution for displaying background images in 3D for raster graphics and vector graphics. This depends on your computer's graphics hardware and the number of currently loaded background images.
|
| AnisoFilt | Anisotropic filtering:  If this option is selected, the display quality of textures is improved when viewed from a very flat angle. |
| Angle | Angle in degrees, by which the background is rotated. The background is also rotated when the Vissim network is rotated (Rotating the network). You can rotate a background in the Network editor (Rotating network objects). |
2. On the list toolbar, in the Relations list, click > Level.
The attribute and attribute values of this network object type are shown in the list on the left, which consists of two coupled lists.
The list on the right contains attributes and attribute values of levels allocated to the network object selected in the list on the left (Using coupled lists).
3. Enter the desired data.
The data is allocated.
