Lets say I have two jpg files. I want to create a series of images, where I move one of the images across the face of the other image. I can already do this in any number of graphical editors, but it takes time to perform the action and then to do a filesave.
But it would be much more useful if I could use a command, or a software to do such a job for me. For example, if I could specify to insert a jpg at a certain offset, and then move it in a certain direction a given number of pixels each time, for a given number of images.
Is there anything which can provide such a functionality?
