Saving an image file

hi!
i have an image file which i load using imshow. then i draw some lines on the figure and save it. the problems is that i cannot save the edited image. how do i do that?

the command i use is something like this:

figure,imshow(imagefile);
line(x,1),y,2),'Linewidth',[1],'Color','k');

i have tried using saveas but it capture the whole GUI image, which i do not want. i only want the image to be save.

Can anyone help?

thank you very much

The print command has some options for saving to graphics file. I use it all the time with plots (I'm not sure if it'll work with what you're doing.

The syntax is something like:

print myfile -dbitmap
print myfile -djpeg

or substitute another clever filename for myfile.
