Polynomial Texture Mapping (PTM) and Reflectance Transformation Imaging (RTI) are common formats for the cultural heritage community. Add an inline viewer for PTM-RTI images and determine needs for extraction service.

Smithsonian Institute has a good example at: http://si.edu/mci/ImagingStudio/Reflectance%20Transformation%20Imaging.html
