Would be interesting how this could be implemented in Qt.

Create a nice looking QtWidget to select a floating point value from a slider.

To have a look :

• https://gist.github.com/dennis-tra/994a65d6165a328d4eabaadbaedac2cc

sRGB but with the 2.2 power function instead

Offer the possibility for the user to preview the image usually produced directly in the interface instead of having to export it somewhere.
(corresponds to the Target/Preview Only option)

Issue

Example I receive the tripled (0.65, 0.03, 0.05) encoded in ACEScg and I would like to know if it's inside sRGB ?

Implementation

CLI

• Create a new subcommand check-color ?
• Or just accept 3 values to check ?

I have a function find_colorspace that can guess accurately the colorspace of a file.
For now the function works around colorspace name in the file's name/parent dir or the chromaticities attribute if it's an exr.
Also add support for file format that can ship with an ICC profile. If it's possible to derive a colorspace from the ICC profile or not.

Necessary to pick the invalid and valid color.

Requirements :

• color-managed
  • view-transform option (colorspace in which the widget is displayed) (make sure to store it in settings)
  • input colorspace (colorspace in which the values in fields are encoded)
  • output colorspace (colorspace in which the values are stored and the later used)
• "preview" state, open the full color editor when clicked
• implement a picker ? (todo later ?)
