Abstract
A method, apparatus and computer program product for importing, exporting and determining an initial state for files having multiple layers is presented. A file having a plurality of layers is imported, the file in a first format and wherein each layer of the plurality of layers includes a first state of the layer and a second state of the layer. One of the first state of the layer and the second state of the layer are displayed for each of the plurality of layers. A swapping is permitted between the first state of the layer and the second state of the layer. One of the first state of the layer and the second state of the layer are then committed. The file may be exported in a format different than the first format.
