man img-ico (3): Img, Windows Icon Format (ico)

SYNOPSIS

package require Tk

package require img::ico ?1.4?

image create photo ?name? ?options?

DESCRIPTION

The package img::ico 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::ico.

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 Windows Icon Format (ico). More specifically img::ico extends Tk's photo image type.

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

All of the above means that in a call like

image create photo ?name? ?options?

[1]: Image data in ico format (options -data and -file) is detected automatically.
[2]: The format name ico 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 ICO OPTIONS.
