A DPX file parser .

File Information

Description

DPX is a high dynamic range file format used for digital motion picture stills and synthetic imagery. The readdpx function extracts image metadata and returns image pixels for each frame.

The DPX format contains numerous bit-depth, pixel layout, and colorspace combinations. This function currently only supports uncompressed 8-bit per sample grayscale and RGB packed images.

This function shows how to use MATLAB's TYPECAST and SWAPBYTE functions to parse files, which is the subject of a January 2006 MATLAB Digest article: <link TBD>.

MATLAB release

MATLAB 7.1.0 (R14SP3)

19 Sep 2007	Amilcar do Carmo Lucas	This is nice but does not provide support for 10 bit per color sample RGB images. So I added support for it. I've e-mailed the author about it, but so far I got no reply. If someone wants the code, just drop me a line.
15 Jan 2008	Amilcar do Carmo Lucas	OK, now I extended the support to 8,10,12,14 and 16 bits per component in both RGB and grayscale, and both big-endian and little endian :)
