img-window - Man Page

package require img::window ?2​.1?

The package img::window 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::window​.

Like all packages of Img it does not provide new commands, but extends the existing Tk command image​. More specifically img::window extends Tk's photo image type​.

The name of the new format handler is window​.

This handler does not provide additional configuration options​. This handler is special​. Instead of reading or writing image data from a file or string, it stores the contents of a Tk window in a photo image​.

All of the above means that in a call like image create photo ?name? ?options?

[1]

Image data in window format (option -data) is detected automatically​. Image data is considered to be in the window format, if the value given to option -data is the name of an existing Tk window​.

Note that the standard option -file is not supported by this handler​.

[2]

The format name window is recognized by the option -format​.
