# img-dted(3tk)

Digital Terrain Elevation Data format (dted)

```

```

## NAME

img-dted - Digital Terrain Elevation Data format (dted)

## SYNOPSIS

package require **img::dted ?2.0?**

```

```

## DESCRIPTION

**package require img::dted**

Like all packages of **Img** it does *not* provide new commands, but extends the existing **Tk** command **image**, so that it supports files containing raster images in the Digital Terrain Elevation Data format (dted). More specifically **img::dted** extends **Tk**'s *photo* \[https://www.tcl.tk/man/tcl9.0/TkCmd/photo.html\] image type.

The name of the new format handler is **dted**. This handler provides new additional configuration options. See section **Options** for more detailed explanations.

All of the above means that in a call like **image** **create photo** ?*name*? ?*options*?

- \[1\]

  Image data in dted format (options **-data** and **-file**) is detected automatically.

- \[2\]

  The format name **dted** is recognized by the option **-format**.

In addition the value of option **-format** is treated as a list and may contain any of the special options listed in section **Options**.

The package **img::dted** is *not* loaded when doing a **package require Img**, but must be loaded explicitly via **package require img::dted**.

## NOTES

- \[1\]

  This format handler interprets DTED elevation files as grayscale images.

- \[2\]

  This format handler only supports read functionality.

## OPTIONS

The handler provides the following options:

- **-verbose** *bool*

  Available since version 1.4.0.

  If set to **true**, additional information about the read data is printed to stdout. Default is **false**.

- **-min** *short*

  Available since version 1.4.0.

  Specify the minimum pixel value to be used for mapping the input data to 8-bit image values. If not specified or negative, the minimum value found in the image data.

- **-max** *short*

  Available since version 1.4.0.

  Specify the maximum pixel value to be used for mapping the input data to 8-bit image values. Default is the maximum value found in the elevation data. If not specified or negative, the maximum value found in the image data.

- **-gamma** *double*

  Available since version 1.4.0.

  Specify a gamma correction to be applied when mapping the input data to 8-bit image values. Default is **1.0**.
