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.
JPEG 2000 Compound Image
JPEG 2000 for multi-layer documents.
JPM (JPEG 2000 Part 6) is a compound image file format. It is designed for storing document images that contain a mix of text and graphics, using a Mixed Raster Content (MRC) model. It allows for different compression methods to be applied to different 'layers' of the image (e.g., sharp edges for text, smooth gradients for photos).
JPM splits an image into multiple layers (e.g., background, foreground mask, foreground color). Each layer can be compressed differently (e.g., JBIG2 for text mask, JPEG 2000 for background photos), optimizing both quality and file size for scanned documents. This is significantly more efficient than compressing an entire scanned page as a single JPEG 2000 image.
Part of the JPEG 2000 standard (ISO/IEC 15444-6), specifically targeting the document archival market.
