Hi I've been trying to save a grayscale image with opened imfreehand line (in my case I set the line up to red colour), but to no avail.
I'd like the saved image exactly as what was seen after drawing the line.
Any helps are much appreciated.
Many regards DE

I thought I already gave you the answer in http://www.mathworks.com/matlabcentral/answers/59898#comment_125529 This looks like the same question. Why wasn't this a follow up to that posting? Why is it a brand new question? It looks the same to me.

rgbImage = cat(3, grayImage, grayImage, grayImage);
for k = 1:length(x)
row = y(k);
column = x(k);
% Assign red, green, and blue values to this pixel.
rgbImage(row, column, 1) = 255;
rgbImage(row, column, 2) = 0;
rgbImage(row, column, 3) = 0;
end
imwrite(rgbImage, fullFileName);
