To export the displayed chart to an image, use-> .
Available formats are SVG, EPS, PS, PDF, and formats that support writing in GdkPixbuf.
To choose a format, you can use an appropriate file name extension, or explicitly select a format in the combo box. With the first method, if GChemTable does not recognize an extension, the exported file will be a SVG file. GChemTable will add an extension to the file name if needed.
You might change the default width and height of the exported image using the appropriate entries.
