Re: [Lcms-user] 32-bit integer ICC profile conversion

[Marti M. <mar...@li...>]

Hi Elle,

Do you mean 32 bits per channel?  96 bits per pixel?

The macro is ok, but you need some code to do the decoding.  It can be 
easily done with a formatter plug-in. Take a look on the plug-in 
documentation, On "Formatters plug-in" section. There is a working example.

Regards
Marti
