Re: [Gimp-user] Equations/Details of the Color Transformations

For most of these filters you find the code and innerloop; which ends
up containing the most important bits of the formula in the sources
for the GEGL operations, like  gegl/operations/common/exposure.c and
also in the folder gegl/operations/common-gpl3+ . However beware that
the innerloop does not tell the whole story; as operations also
constrain the type of pixel encodings they accept. For instance
gegl:exposure ensures that the component values are linear, the math
would be wrong if applied to 8bit sRGB data or floating point sRGB

Hi All,

I am interested in the color transformations of the tools like
brightness-contrast, hue-chroma, hue-saturation, saturation, exposure, color
balance, color temperature, ...

Do you know where I can find the details of these tools, in particular the
mathematical equations behind them?

Thank you in advance for your help.
