uff, not really. will have to look at the source again as well. but out of the
blue i'd say each framework is doing it independent from the other with
GeoImage/ReferencedImage being the newest one and most elaborate, trying
worldfile, gdal or geotiff to fetch referencing, not saying accurate though.
check package com.vividsolutions.jump.workbench.imagery
where the sub packages contain the different "frameworks", which at least
internally should reference the same way.
geoimg eg. does it in geoimg.GeoReferencedRaster.readRasterfile()
geotiff similarily in geotiff.GeoTIFFRaster.readRasterfile()
graphic (incl. Commons) does it during painting in
graphic.AbstractGraphicImage.paint(Feature f, Graphics2D g, Viewport viewport)
imagio can be ignored, contains no ImageFactory but gdal readers. maybe we
should move them somewhere else.
mrsid up to you ;)
rendering as well is independent in each framework and you might look at either
patching the rendering, usually the paint() method or the envelope fetching.
something like that ..ede

** [bugs:#503] 1/2 pixel shift in image georeferencement**

There is still 1/2 pixel difference between image georeferenced with Sextant
Raster reader and images georeferenced with other readers. I have not
investigated yet and don't know which one is correct.
