NAME

       img-ppm - Img, Portable Pixmap format (ppm)

SYNOPSIS

       package require Tk

       package require img::ppm  ?1.3?

       image create photo ?name? ?options?

DESCRIPTION

       The  package  img::ppm  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::ppm.

       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 Portable Pixmap format (ppm). More specifically img::ppm extends Tk's photo image type.

       The name of the new format handler is ppm.  This handler does not provide additional configuration options.

       All of the above means that in a call like

       image create photo ?name? ?options?

       [1]    Image data in ppm format (options -data and -file) is detected automatically.

       [2]    The format name ppm is recognized by the option -format.

SUPPORTED PPM TYPES

       There are two types of PPM files: RAW (binary) and ASCII.  Currently only the RAW format is implemented.
	 8-bit pixels: Grayscale, also known as PGM.
	24-bit pixels: True-color (RGB, each channel 8 bit).

	List of currently supported features:

	Type   |     Read      |     Write     |
	       | -file | -data | -file | -data |
