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

[Victor Gimenez]

Hi Andreas,



The figure that topoplot returns me is from surface type with 12 
attributes as: CDataModel, VertexNormalsMode, FaceNormalsMode... i am 
reading the print documentation but I can't able to see nothing where 
could I find to pass the img from surface type as a parameter, any tips?

I am doing the code as:

img = topoplot(EEG.data(1,1:3071,3),EEG.chanlocs,'style','map');


Thank you,

Victor
