Samsung RAW
The raw format for Samsung's defunct NX camera line.
SRW is the proprietary raw format used by Samsung's NX series of mirrorless cameras (like the NX1 and NX500). Although Samsung exited the camera market, the NX1 remains a cult classic for its high-resolution sensor, and SRW files are still relevant for its users.
SRW files are TIFF-based containers holding the raw sensor data. The NX1's SRW files are particularly notable for containing data from a 28MP BSI-APS-C sensor, which was ahead of its time.
Introduced with the Samsung GX series (rebadged Pentax) and evolved with the NX series.
Portable Any Map
A super-class extension for the PBM, PGM, and PPM formats.
PNM (Portable Any Map) is not a distinct file format itself but rather a collective name (and file extension) used to handle files that could be any of the specialized Netpbm formats: PBM (Bitmap), PGM (Graymap), or PPM (Pixmap). A file ending in `.pnm` allows a program to implement a single reader that automatically detects the internal format ('P1' through 'P6') and handles it accordingly.
A `.pnm` file is simply a PBM, PGM, or PPM file renamed. The header magic number (e.g., `P6`) determines the actual content. This abstraction simplifies command-line pipelines, allowing users to pipe `image.pnm` without worrying if the image is black-and-white or full color.
Part of the Netpbm project philosophy to create a unified library for handling raster graphics. It simplifies naming conventions for software that can output any of the subtypes.
