[Eeglablist] Generate jpg, png, gif formats through topoplot function without the need to save it manually

[Andreas Widmann]

print( '-dpng', 'somefilename.png', '-r300‘ )
exports the current figure as png from the CLI (with 300 dpi resolution). Same principle for jpg, etc.

Adding a figure handle to the print command can be helpful if plotting and exporting multiple figures (e.g., in a loop):
figHandle = figure;
your_plot_command
print(figHandle, '-dpng', 'somefilename.png', '-r300‘)

Hope this helps! Best,
Andreas
