IGI file format

[galinette]

Dear Indigo team,

Still working for "color proofness" when doing renders with spectral data, I'm interested in accessing the raw Indigo data. Currently, I'm using the EXR values, but they are white-balance corrected, which make things difficult (I do not know how the white balance is performed internally by Indigo)

My question is:
- Which colorspace is stored in the IGI file? I suppose it is not spectral but trichromatic. Are the values encoded with a standard XYZ observer? Are they already converted to RGB?
- How could I access the data? Is the format open?

Thanks,

Etienne

The format is public domain, read more about it here: http://www.indigorenderer.com/forum/vie ... =25&t=1268

Still dreaming of a IGI Photoshop import PlugIn with Layer support etc.

Looks great, I will then have direct access to XYZ data.

Thanks!

Hello,

It seems the format version number is now 5. I hope the start of data position did not change, but what are the differences between igi v4 and igi v5?

Thanks,

Etienne
