Usage

Overview

package require img::xbm

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 X Windows Bitmap format (xbm). More specifically img::xbm extends Tk's photo [https://www.tcl.tk/man/tcl9.0/TkCmd/photo.html] image type.

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

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

In addition the value of option -format is treated as a list and may contain any of the special options listed in section Options.

The package img::xbm 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::xbm.
