Hi Garrett and Oscar
I updated the ossim, gdal_plugin, and png_plugin source last night. The
changes include:
1. Lots of typecasts away from size_t to get rid of many Visual Studio
warnings during compilation.
2. Adding in the virtual reader/writer/overview builder (8 new files).
ossimVirtualImageHandler.cpp
ossimVirtualImageTiffWriter.cpp
ossimVirtualImageWriter.cpp
ossimVirtualOverviewBuilder.cpp
ossimVirtualImageHandler.h
ossimVirtualImageTiffWriter.h
ossimVirtualImageWriter.h
ossimVirtualOverviewBuilder.h
These classes are used to build and read frame-based images, i.e. made up
of lots of smaller images like RPF. The multi-res structure is similar to
super kml used in Google Earth, but so far the individual frames are
geotiff. Ill be adding in PNG support soon. The writer classes can do
partial rebuilds of the overviews, i.e. you can specify localized areas to
rebuild and leave the rest alone. This is exposed so far in the img2rr
utility via the new f option, where you can specify individual RPF frame
images that might have been added or changed. I also added a list-frames
option to print out all the individual frames names of an RPF, to help in
identifying frames by their entry, row, and col location in the RPF.
I updated the ossim\imaging\makefile.vc for these new files, but not the
projects/vs/ossim/ossim.vcproj because we're using VS 2005 instead of
2008. VS 2005 doesnt seem to handle the VS 2008 vcproj and sln files.
3. Changes to gdal_plugin (and ossim core) for correcting some image
positioning problems we were experiencing over the last year and a half
with EarthWhere.
4. Optional Supplementary path location for storing the output of
orthoigen.

Eric Hirschorn @ SPADAC
