Subject: bigarray & int24
Date: Mon, 31 Mar 2008 11:58:09 +0200	[thread overview]
Message-ID: <BB046CA812535C45BD0029AA9D04BA7902C90A60@KL-SRV57.lmsintl.com> (raw)

Hi,

my program should read unaligned 3 byte integers. (A real world
example for such a format would be an RGB image). What is
the best approach?

  - extend bigarray for the int24 format and send the patch to INRIA
  - write a C-function, which converts the data to an int32-array
  - read an 1-byte-bigarray and construct an int-bigarray
  - ???

It should be a bigarray solution, because my program reads other
(supported)
formats as well.

Speed matters, because there are a lot of data.

Thanks,

Christoph Bauer
