I would line it to automatically take multiple lines across the whole image, from one end to another(i would like to specify how many sample lines should be taken in an image) and provide the the gray level variations across each line as data.

A sample image is added here (http://snag.gy/AZXST.jpg). As you can see in this image from end to end a line intensity profile is chosen and plotted.

I want it to be drawn for multiple lines(i should be able to choose the number of lines) and
Instead of using a cursor and drawing a line end to end i want to automatically draw a line across the image.

Thank you for patiently reading.
