NAME

       img-dted - Img, DTED Format (dted)

SYNOPSIS

       package require Tk

       package require img::dted  ?1.4?

       image create photo ?name? ?options?

_________________________________________________________________

DESCRIPTION

       The  package  img::dted is a sub-package of Img. It can be loaded as a part of the complete Img support, via package require Img, or on its
       own, via 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 DTED Format (dted). More specifically img::dted extends Tk's photo image type.

       The  name of the new format handler is dted.  This handler provides new additional configuration options. See section DTED 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 for the option is treated as list and  may  contain
	      any of the special options listed in section DTED OPTIONS.

NOTE

       This format handler must be loaded explicitly with package require img::dted.

SUPPORTED DTED TYPES

	Interpret DTED terrain elevation data as a grayscale image.

	List of currently supported features:

	Type   |     Read      |     Write     |
	       | -file | -data | -file | -data |
	----------------------------------------
	Gray   | Yes   | Yes   | No    | No   |

DTED OPTIONS

       The handler provides the following options:

       -verbose bool
	      If set to true, additional information about the loaded image is printed to stdout. Default is false.

       -nchan int
	      Specify the number of channels of the generated image.  Default is 1, i.e. generate a grayscale image.

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

       -nomap bool
	      If  set  to  true, no mapping of input values is done.  Use this option, if your elevation file contains values in the range of 0 ..
	      255 only.  Default is false.

       -min short
	      Specify the minimum pixel value to be used for mapping the input data to 8-bit image values.  Default is the minimum value found	in
	      the elevation data.

       -max short
	      This option is supported for reading only.

	      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.
