The appearance of the main form changes depending on the type of image and what you are doing at the moment. This ensures that only appropriate values can be changed and that only appropriate buttons can be clicked. The controls discussed are not difficult - you could determine how they work with just a little experimentation. MBF supports two different locations for most of the controls on the form, one with the controls below the Picture Box, and one with the controls above the Picture Box.";
