DPX file reader

A DPX file parser .

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)

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.

[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 :)

Hi, I havent found .m file with extension fot 10bit dpx, can it be downloaded somewhere ?

[Do Quoc Bao]

Very useful !!
But I want a code which can read RGB 10 bit dpx :(

[Ram prasad]

Thank you. very useful file for me.
dear 'Amilcar do Carmo Lucas' please tell me how to download your version of the file (ie 10 bit support). or please send me a copy at [e-mail]
Thank you very much

[Andrew Léonce]

Hello, I would also like to have a copy of the extended version of this script. If you would be so kind as to leave a link on here so that it is available, that would be fantastic.

Kind regards,
Andrew

Would anyone tell me how to extend this code to handle 10 and 12 bit images? Thank you.

It is useful for me.

I'm also looking for the version with support of 10 bit RGB. Can anyone e-mail it to me or advise me on where it can be downloaded.
