I got my maps working yesterday evening. There was not much of a learning curve for me on this one since WinAPRS uses the same format with the exception of the image size field and that was easy. I am currently having tie point accuracy issues but I can get that taken care of. My maps are not lining up to the Tiger maps, sometimes off by close to a half mile and distorted image. For the record, I have that issue with WinAPRS sometimes to so I believe it is a LONG/LAT to pixel problem on my end. I fixed those so I know I can fix these. I will play with it more as time permits.
Thanks.
