I have a program that needs to be able to reproject (GIS imagery) on the fly. As in if you import a new file, it will re-project it into the documents coordinate system, and if the documents coordinate system is changed, re-project all layers.
There is an open sources library for this called GDAL. the problem is, all of its functions work on files. Would I need to write my NSImage to file, convert it then re import it into my program? or is there a better way? or would I need to rewrite the functions in Obj C?
