I write Scientific Imaging software that writes TIFF files. I recently add the ability to locate photons in an image with sub-pixel accuracy. The original image is then discarded and a new image can be created from the list of photons. I want to write a TIFF file that provides this list instead of the standard raster image. I already registered an IFD tag with Adobe for this purpose and I already devised a scheme.

It seems that no one has responded.

TIFF is (by definition) primarily a raster format which may be augmented with additional data. It does not make sense without a raster image. Without a raster image, it is unlikely that any other software will ever read your format.

Perhaps you should consider a more vector-oriented standard format like SVG which can be used to incrementally produce a raster image of any size from your photon data. Certain "plot" oriented formats may also work.
