NAME

img-flir - Img, FLIR FPF Public Image Format (flir)

SYNOPSIS

package require Tk

package require img::flir ?1.4?

image create photo ?name? ?options?

DESCRIPTION

package require img::flir.

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 FLIR FPF Public Image Format (flir). More specifically img::flir extends Tk's photo image type.

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

All of the above means that in a call like

image create photo ?name? ?options?

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

NOTE

This format handler must be loaded explicitly with package require img::flir.
