Re: [Openexr-devel] Color Space SettingsDear Chris,
Thank you for your answer. I have already added the sRGB and Linear from
the EXIF tags.
It would be nice as well to have rec709 supported there. In LightWave, it you
load a JPEG
or TIFF, it will auto sense the color space now. I am trying to expand those
setting to
openexr. Because it is a very popular format now.

Um, no. JPEG and TIFF each have tags that allow you to embed an ICC profile
(which can specify anything about the colorspace of the document).
They do not have explicit tags saying 'sRGB' or "Linear" (unless you count
EXIF extensions, that allows for "sRGB, AdobeRGB, and unknown" and none of
those are linear).

I am working on loading and saving color space information in several file
formats.
JPEGs and TIFFs contain a tag to know of the image was created as sRGB or
Linear.
What I want to do is identify the color space of the loaded image and be
able to set
the color space when I save the image. Common color spaces are Linear,
sRGB
and rec709.
I would like some sample openexr images with color space setting in them and
any documentation about the color spaces.
