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 Network Graphics
JPEG compression with PNG transparency.
JNG (JPEG Network Graphics) is a sub-format of the MNG animation format. It was designed to combine the high compression of JPEG with the alpha transparency features of PNG, something that standard JPEG lacks. It essentially wraps a JPEG stream and a mask channel in a chunk-based container.
A JNG file structure mimics PNG. It uses a 8-byte signature and chunks. The image data is split into a color chunk (JDAT) which contains JPEG data, and an alpha chunk (IDAT) which contains PNG-compressed alpha mask. This allows for 'lossy color, lossless alpha' images, which is very space-efficient for photographic sprites.
Created by the PNG Development Group around 2001 as part of the MNG (Multiple-image Network Graphics) project. It failed to gain traction as MNG was rejected by Mozilla and Chromium in favor of APNG and later WebP.
