Hello, A few days ago, I asked if it could be possible to use the colorimeter from the french project HCFR with argyllcms tools to build ICC profiles. Now, I'm wondering if I could use my DTP92, instead of the DIY colorimeter, with the HCFR software, to calibrate a video-projector. The author of the software said to me that if the colorimeter can output XYZ values (which I think DTP92 does), there is no problem. So, I would like to know what part of the argyllcms code I need to build a minimalistic library to drive the DTP92 and have it return XYZ values ? Thanks, -- Frédéric http://www.gbiloba.org
