The supported image formats are dependent on the system environment. Plots can always be exported to the Postscript format. Exporting displays as .pdfs is only possible when the command line tool epstopdf is installed. Finally, exporting to either png, jpg, bmp, tiff or gif requires the Img Tcl extension. When choosing one of the formats that depend on the Img extension, it is possible to export any Tk widget as an image including inspectors.
