Attached a modification that read the HeigthField position and X,Yintervals.
I also removed the limitation to 1024*1024 to 4096*4096, because when you are preprocessing your data with OSG, it can be useful to read large images/heigthfields. Is there a reason (other than hardware limitations for textures) for this limit ?"
There is a small issue though ... GDALRasterBand::GetColorInterpretation()
is not implemented for ecw images (in GDAL's sources I downloaded today)
... I put small hack in there to interpret the bands based on their index
and it seams to work .."
instead of osgDB::Registry where it original lay. This has been done to allow
fileName strings to be encode data rather than just file names, such as one
requires when using PagedLOD along with plugins for doing dynamic tesselation.
