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.
l_export(widget, filename, width, height)path to the exported file
widget path as a string or as an object handle
path of output file
image width in pixels
image height in pixels
Note that the CTRL-P key combination opens a dialog to export
the graphic.
The native export format is to ps as this is what the Tk canvas
offers. If the the l_export fails with other formats then please
resort to a screen capture method for the moment.
