# d.rast

Displays user-specified raster map in the active graphics frame.

=== "Command line"

    **d.rast**
    [**-ni**]
    **map**=*name*
    [**values**=*value[-value]* [,*value[-value]*,...]]
    [**bgcolor**=*color*]
    [**--verbose**]
    [**--quiet**]
    [**--qq**]
    [**--ui**]

    Example:

    ```sh
    d.rast map=name
    ```

=== "Python (grass.tools)"

    *grass.tools.Tools.d_rast*(**map**,
        **values**=*None*,
        **bgcolor**=*"white"*,
        **flags**=*None*,
        **verbose**=*None*,
        **quiet**=*None*,
        **superquiet**=*None*)

    Example:

    ```python
    tools = Tools()
    tools.d_rast(map="name")
    ```

    This grass.tools API is experimental in version 8.5 and expected to be stable in version 8.6.

=== "Python (grass.script)"

    *grass.script.run_command*("***d.rast***",
        **map**,

        **flags**=*None*,
        **verbose**=*None*,
        **quiet**=*None*,
        **superquiet**=*None*)

    Example:

    ```python
    gs.run_command("d.rast", map="name")
    ```

## DESCRIPTION

*d.rast* displays the specified raster map in the active display frame
on the graphics monitor.

## EXAMPLE

Display raster map "elevation":

```sh
d.rast map=elevation
```

![d.rast elevation](d_rast_elevation.png)  
*Figure: elevation raster map visualization*

Display raster map "elevation" but only the raster cells with values
between 75 and 80 meters:

```sh
d.rast map=elevation values=75-80
```

![d.rast elevation with values](d_rast_elevation_values.png)  
*Figure: elevation raster map showing values between 75 and 80 meters*

Display raster map "landuse96_28m" but only categories 1 and 2:

```sh
d.rast landuse96_28m values=1,2
```
