In the XA/XRF Grayscale Softcopy Presentation State IOD, the Presentation Series Module specializes some Attributes of the General Series Module, the XA/XRF Presentation State Mask Module specializes some Attributes of the Mask Module, and the XA/XRF Presentation State Shutter Module specializes some Attributes of the Bitmap Display Shutter Module and Display Shutter Module.

### Note

1. Subtraction between different images is not supported.

2. The Display Shutter may be used to darken image areas that surround important information and exclude extraneous bright areas that increase glare and ambient lighting impairing image interpretation. For example, unexposed areas in a XA image might be obscured using the Display Shutter, rather than permanently replacing image pixels in those areas.

3. This IOD does not support the storage of a multi-frame overlay in the IOD itself, but does support selective activation of multi-frame overlays within the referenced images via the Overlay Activation Module.
