img-sun

img-sun(n)																img-sun(n)

NAME

       img-sun - Img, Sun Raster Format (sun)

SYNOPSIS

       package require Tk

       package require img::sun  ?1.3?

       image create photo ?name? ?options?

DESCRIPTION

       The  package  img::sun  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::sun.

       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 Sun Raster Format (sun). More specifically img::sun extends Tk's photo image type.

       The  name  of  the new format handler is sun.  This handler provides new additional configuration options. See section SUN OPTIONS for more
       detailed explanations.

       All of the above means that in a call like

       image create photo ?name? ?options?

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

       [2]    The format name sun 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 SUN OPTIONS.

SUPPORTED SUN TYPES

	 1-bit pixels: Black and White.
	 8-bit pixels: Grayscale or indexed.
	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 |
	----------------------------------------
	 1-bit | Yes   | Yes   | No    | No    |
	 8-bit | Yes   | Yes   | No    | No    |
	24-bit | Yes   | Yes   | Yes   | Yes   |
	32-bit | Yes   | Yes   | Yes   | Yes   |

	All images types may be either uncompressed or run-length encoded.

SUN 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.
