Obscure Photoshop bug

PS 6, but due to its obscure nature, probably other versions too. Windows 98.

Recording an action to save a file as RAW does *not* save the Interleave and Byte Order information correctly.

Regardless of what these two options are set to when the action is recorded, the settings are ignored and Interleaved=On and Mac byte order are used.

Since the development was probably done on the Mac this slipped by. That’s what happens when the developers use an obscure OS… ;o)
That’s the second bug in RAW file handling!!

Any ideas for a workaround? Does anybody know internal Actions file layout so I can retrofit this manually?

Don.

Interleave I can understand, but is there some reaso byte order matters these days?

Yes, in 16-bit images.

It’s the big-endian / little-endian thing whereby the order of bytes is reversed between Mac and PC.

I’m familiar with that tweakiness back when it mattered to the TIFF you were saving; nowadays, you can flop the byte order around in a TIFF and it will still open on the Mac or Peecee with no problem. That’s not true with 16-bit images? Interesting.

Of course, in theory, it’s possible to save any which way and then specify the same when opening e.g. I can have the action open a Mac byte order file on the PC by explicitly specifying that the file has Mac byte order (and thereby skipping a separate conversion step). And the same goes for Interleave too.

However, that would be a major kludge and it’s not self-documenting leading to a possible confusion months later after I forget all about this particular Photoshop "eccentricity".

So, I just made all Save actions modal. That way I get a dialog each time. On the minus side that means I have to specify all this by hand and can’t have the action run unattended, but on the plus side I’m sure I don’t miss any files, and since they are quite big, I still get time to do other things between saves.

The OP is using RAW format, so the software at the reading end is presumably assuming/enforcing a particular ordering (unlike, as you say, any intelligent TIFF reader).
