I have a need for work to batch process thousands of images from .RLE and .CIT to say .JPG, .TIF, or even .PDF. Does anyone know of a software package that will do this? I know the .RLE and .CIT were old Intergraph and MicroStation images produced by these CAD workstations. This is what makes them a little unique as far as images are concerned.

I'd like to point to a directory and have the software search for the images of interest and if found, create a duplicate in .JPG, .TIF, etc. at that same location.

I don’t know for sure, but take a look at the companies Kofax and Abbyy. They are two of the big dogs in bulk image processing. Maybe one of their products will handle those formats, but I don’t know for sure.

You may be able to use Imagemagick to do this. It at least appears to support the rle file type.
