Img is a Tk extension, adding support for many other
    Image formats, as listed below. The individual formats are described in more
    detail on their own pages.



  

  
Windows bitmap format. See img-bmp.

  

  
DTED terrain elevation data interpreted as image. See
    img-dted.

  

  
The venerable graphics interchange format (with transparency, but without
      LZW. The latter due to patent issues). See img-gif.

  

  
Windows icon files. See img-ico.

  

  
The format for lossy compressed still pictures specified by the Joint
      Picture Experts Group. See img-jpeg.

  

  
Paintbrush image format. See img-pcx.

  

  
While the other formats are handlers for the Tk photo image type
      this is a new image type for Tk. See img-pixmap.

  

  
Portable Network Graphics, successor to GIF. See img-png.

  

  
Portable Pixmaps. See img-ppm.

  

  
Postscript and PDF (Portable document format). Requires an external
      application, ghostview, for its operation. See img-ps.

  

  
Raw matrix data interpreted as image. See img-raw.

  

  
Native SGI format. See img-sgi.

  

  
Sun raster images. See img-sun.

  

  
Targa files. See img-tga.

  

  
Tagged Interchange File Format. See img-tiff.

  

  
Put the content of a Tk window into an image. See img-window.
