NAME


img-gif - Graphics Interchange Format (gif)






SYNOPSIS


package require img::gif ?2.0?










DESCRIPTION


package require img::gif


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 Graphics Interchange
    Format (gif). More specifically img::gif extends Tk's
    photo [https://www.tcl.tk/man/tcl9.0/TkCmd/photo.html] image
  type.


The name of the new format handler is gif. 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?

Image data in gif format (options -data and -file) is
      detected automatically.

The format name gif is recognized by the option
    -format.




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::gif is not loaded when doing a
    package require Img, but must be loaded explicitly via package
    require img::gif.
