Gary Lucas commented on SANSELAN-54:
------------------------------------
I have implemented fixes for this. The changes were quite minor. I tested them
against the output from Java's NIO ByteBuffer class (on the theory that Java
can serve as a baseline implementation). Since I'm pretty new to Apache and
its procedures, I was wondering if somebody wanted to "mentor" me on turning
this in (review my code, etc.).
> Tiff (exif) tags of type double written in wrong byte order
> -----------------------------------------------------------
>
> Key: SANSELAN-54
> URL: https://issues.apache.org/jira/browse/SANSELAN-54
> Project: Commons Sanselan
> Issue Type: Bug
> Environment: Tested under Windows XP. Potentally all platforms.
> Reporter: Gary Lucas
>
> Reviewing BinaryFileFunctions.java method convertDoubleToByteArray and
> convertDoubleArrayToByteArray there are two blocks of code, one for
> BYTE_ORDER_MOTOROLA (big endian) and one for BYTE_ORDER_INTEL (little
> endian). These are backwards.
> The convertByteArrayToDouble, on the other hand appears to be correct. A
> reasonable test procedure would be to see if these two sets of methods are
> mutually consistent.
> The same problem appears to be the case for the "Float" variants, but not the
> Integer variants.
