how to use export_fig to save an image without the margin

Hi People,

Please I want to use export_fig to save an image without the margin.

[Amin Abedini]

X = 1:1:10;

Y = 1:1:10;

F = figure

plot(X,Y);

set(gcf,'color','w');

%%%%%%%%%%%%%%%%%%%

FigName = 'FigWithNoBorder';

export_fig FigName.png '-r300' % Saves as png with 300 resolution.
