eeg_save_graphics

 eeg_save_graphics - Save figure as graphics file
 
 Usage: eeg_save_graphics(F,type,p,confirm)
 
 'F' is a figure handle, when empty uses 'gcf'
 
 'type' is the format of the graphic file, eg:
 
       'png'  - portable network graphics (default)
       'jpg'  - JPEG image, quality level of 90
       'tiff' - TIFF with packbits (lossless run-length encoding)
       'eps'  - encapsulated postscript
 
 Note that tiff and eps files can be very large.
 The default resolution is 300 DPI.
 
 'p' is the data struct of eeg_toolbox
 
 'confirm' is a boolean to control direct or GUI
 based saving.  0 = direct, 1 = GUI confirmation.
 
 The output file is saved to p.volt.path with
 the filename of the voltage file and the timing
 of the graphic appended (assumes that the graphic
 is a topographic map).
