packagerequireimg::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 imagecreatephoto ?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 packagerequireImg, but must be loaded  explicitly  via
       packagerequireimg::dted.
