Thread Subject: saving displayed image from imagesc

i would like to save the resultant gradual image displayed from imagesec command into file or variable for later processing so that it holds image displayed.

this is my chunk code, i want to save (K) in file or make imshow for it later
_________________________
img=im2double(imread('c:\1.tif'));
[x,y] = gradient(img);
 mag = sqrt(x.*x+y.*y);
th = atan2(y,x);
figure ; K=imagesc(th.*mag);
____________________________
how can i save and process image stored in K?

regards.

Hi Hassan,

look into "imwrite" and "imread".
