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. SEE ALSO

NAME
img-tga - Img, Truevision Targa Format (tga) SYNOPSIS
package require Tk package require img::tga ?1.4? image create photo ?name? ?options? _________________________________________________________________ DESCRIPTION
The package img::tga 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::tga. 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 Truevision Targa Format (tga). More specifically img::tga extends Tk's photo image type. The name of the new format handler is tga. This handler provides new additional configuration options. See section TGA OPTIONS for more detailed explanations. All of the above means that in a call like image create photo ?name? ?options? [1] Image data in tga format (options -data and -file) is detected automatically. [2] The format name tga 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 TGA OPTIONS. SUPPORTED TGA TYPES
24-bit pixels: True-color (RGB, each channel 8 bit). 32-bit pixels: True-color with alpha channel (RGBA, each channel 8 bit). List of currently supported features: Type | Read | Write | | -file | -data | -file | -data | ---------------------------------------- 24-bit | Yes | Yes | Yes | Yes | 32-bit | Yes | Yes | Yes | Yes | All images types may be either uncompressed (Targa-Type 2) or run-length encoded (Targa-Type 10). TGA OPTIONS
The handler provides the following options: -verbose bool This option is supported for reading and writing. If set to true, additional information about the loaded/stored image is printed to stdout. Default is false. -compression type This option is supported for writing only. Set the compression mode to either none or rle. Default is rle. -matte bool This option is supported for reading and writing. If set to false, a matte (alpha) channel is ignored during reading or writing. Default is true. SEE ALSO
