I have the folowing code ,plz tell how to save the circled image
k is my image
function [x1 y1 r ] = circle_saptha4(k)
ok = 0;
nim = k;
while ok~=1
% figure;
imshow(nim);
pt = ginput(2)
x1 = pt(1,1);
y1 = pt(1,2);
x2 = pt(2,1);
y2 = pt(2,2);
xpt = [x1 x2];
ypt = [y1 y2];
%line(x,y); % Enablw this for draw rectangle on circle
r = sqrt((x2-x1)^2 + (y2-y1)^2)
pp=rsmak('circle',r,[x1 y1]);
% figure;
% imshow(k)
fnplt(pp);
line(xpt,ypt);
xtl = x1-r;
xtr = x1+r;
xbl = x1-r;
xbr = x1+r;
ytl = y1+r;
ytr = y1+r;
ybl = y1-r;
ybr = y1-r;
x = [xtl xtr xbr xbl xtl];
y = [ytl ytr ybr ybl ytl];
%line(x,y);
for i=1:size(k,1)
for j=1:size(k,2)
x2 = j;
y2 = i;
val = floor(sqrt((x2-x1)^2 + (y2-y1)^2));
if(val == floor(r))
nim(i,j,1) = 255;
nim(i,j,2) = 0;
nim(i,j,3) = 0;
% else
% nim(i,j,1) = k(i,j,1);
% nim(i,j,2) = k(i,j,2);
% nim(i,j,3) = k(i,j,3);
% end
end
end
ok = (menu('Do u want to draw another circle?','No','Yes')==1)
% hold on
end
end

Why not use rectangle() to draw the circles into the overlay, then use export_fig (from the File Exchange) to save the image with the circles written into the image?

Why do you change nim after you display it?
Why do you return x1 y1 only for the newest circle, instead of for all circles? You never even displayed that newest circle on the drawing.
What is your reason for saying "I did it but it writes only 256" ? What writes only 256 ?
