img-sun - Img, Sun Raster Format (sun)
package require Tk package require img::sun ?1.3? image create photo ?name? ?options?
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?  Image data in sun format (options -data and -file) is detected automatically.  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.
