In the Blending Softcopy Presentation State IOD, the Presentation Series Module specializes some Attributes of the General Series Module.

The Softcopy Presentation LUT Module shall not be present in this IOD.

The VOI LUT Module and Softcopy VOI LUT Module shall not be present in this IOD, since the Presentation State Blending Module subsumes their function.

The Palette Color Lookup Table Module describes the color mapping to be used for the superimposed image set.

The Displayed Area Module and Graphic Annotation Module specifically identify those images or frames to which they apply, and may include images or frames from the underlying or superimposed set.

The Spatial Transformation Module describes any necessary spatial transformation of the image to be rendered after the blending operation.

The Overlay Plane Module and Overlay Activation Module shall not be present, and any overlays present in the referenced images shall not be displayed.

The Display Shutter Module and Bitmap Display Shutter Module shall not be present, since the underlying image geometry may differ between the two sets of images.

The ICC Profile Module shall always be present. If the color space to be used is not calibrated (i.e., a device-specific ICC Input Profile is not available), then an ICC Input Profile specifying a well-known space (such as sRGB) may be specified.
