[Lcms-user] Serializing CIELab to buffer

[Aaron B. <bo...@gm...>]

Hello Everyone,

I have a JPEG 2000 image with a stored CIELab color profile.
This profile is determined by 7 32 bit values.

My code currently uses LCMS to apply the profile to the image before
decoding to TIFF.
I would prefer to store this color profile in the TIFF image.
I can do that if I can serialize the profile into a buffer of bytes.

I am using LCMS to apply the CIELab as follows:

        cmsHPROFILE in = cmsCreateLab4Profile(nullptr);
        cmsHPROFILE out = cmsCreate_sRGBProfile();
        cmsHTRANSFORM transform =
            cmsCreateTransform(in, TYPE_Lab_DBL, out, TYPE_RGB_16,
INTENT_PERCEPTUAL, 0);


and then applying the transform to each pixel.

Is there a way of serializing this profile to a memory buffer, so that I
can store it in the TIFF file?

Thanks so much,
Aaron
