About MRW Format

Minolta RAW

The raw format of the Konica Minolta era.

Overview

MRW is the raw image format used by Minolta and Konica Minolta digital cameras (like the DiMAGE series and the Maxxum/Dynax 7D) before the camera division was sold to Sony in 2006. MRW files contain the raw sensor data from these early DSLRs and bridge cameras.

Technical Details

MRW files are not TIFF-based; they use a proprietary structure. They typically store 12-bit sensor data.

History

Minolta was an innovator (first IBIS in a DSLR). When Sony bought them, they used the technology to build the Alpha system. The MRW format was replaced by Sony's ARW.

Common Use Cases

  • Archival: Legacy photos.

Advantages

  • Minolta Colors

Limitations

  • Obsolete

About PGX Format

JPEG 2000 VM Uncompressed

A single-component test format for JPEG 2000 verification.

Overview

PGX is an extremely simple, uncompressed raster format created specifically for the development and testing of the JPEG 2000 standard (ISO 15444). It is defined in the JPEG 2000 Verification Model (VM). Its purpose is to store a single component (channel) of an image with potentially high bit depth and signed/unsigned values, without the complexity of a full image container.

Technical Details

A PGX file represents one image channel (grayscale). It starts with a minimalist text header identifying the endianness (`LMS` or `Big`), the sign (`+`/`-`), the bit depth, and dimensions. The raw pixel data follows immediately. It is effectively a raw dump of a single image plane.

History

Developed by the JPEG committee during the creation of JPEG 2000. It allowed researchers to test wavelet compression algorithms on raw data without worrying about file headers or color transforms.

Common Use Cases

  • Algorithm Testing: Testing a new wavelet transform implementation.
  • JPEG 2000 Component Separation: Storing the separated Y, U, and V channels of an image before compression.

Advantages

  • Precision

Limitations

  • Grayscale Only
  • Obscure
