Re: [Oiio-dev] [Oiio-announce] OpenImageIO 1.6.9

I think it should be the other way around as I expect production builds to be smallest possible to speed up any IO when software is installed on network storage. It’s a bit like saying your expecting the software to crash so make the library 3x bigger.. OIIO is pretty stable in most places I se

Can contrast also have a pivot parameter please? Depending on the luminance encoding of the image this needs to be diffrent. On 23/06/2012, at 2:43 PM, Chris Foster wrote: > On Sat, Jun 23, 2012 at 7:24 PM, Stefan Stavrev > wrote: >> I implemented everything we talked about so far, so you can
