Samsung SRW is a raw image format used by some Samsung digital cameras. It is based on TIFF.
The full-resolution image is in one of the subIFDs (the second of two?) of the first TIFF IFD. SRW seem to be missing TIFF required ImageLength field.
One of the subIFDs of the first TIFF IFD has Compression code 32770 (or maybe 32772?).
