Dear all,
I am interested to increase the line width in imfreehand and also it should not be poly. To avoid poly I do this.
test = imfreehand('Closed',0);
which works fine. Now How can I increase the line width. I am using MATLAB 2015.

test = imfreehand('Closed',0);
pos = test.getPosition();
plot(pos(:,1),pos(:,2),'linewidth',5) ;

The new freehand ROI drawfreehand has a LineWidth property:

As an example:
imshow('peppers.png')
h = drawfreehand('LineWidth',10);

I don't see anyway to control the linewidth "live" as you draw the shape. The only way to show a different thickness line is to plot it, after you're all done drawing, with the plot() function and specify the 'LineWidth' property as KSSV showed you.
