What does libtiff do now with 24 bit integer values? Presumably we should do the same thing with this and with the 24bit float values, right? I'm afraid I don't know what that is, though with some help from Bob I did manage to muddle my way through implementing support for tiff files with odd bit depths in my application.


This issue was already discussed several times in the past. libtiff does the right thing with 24-bit samples (as per Chris' explanation) and GDAL does the right thing too. Just search for TIFFSwabArrayOfTriples() definition and its usage. All 24-bit floating point samples from Chris work fine in OpenEV for a long time.
