- I have the following problem:
-
- I am working with huge sunraster files (27152x37937 pixels)
- which are run_length encoded. Since I don't have enough memory
- to load the whole picture, I have to cut it into smaller pieces.
-
- Because of the run-length encoding, I have to read all the bytes
- of the file to find the starting position of the sub-image. For
- huge files, this means hours of computing.
-
- Does anybody know a better way to cut run-length encoded rasterfiles?
-
- Thanks.
