View Transform Toolbar

The View Transform Toolbar displays a number of options for managing your monitor's colorspace in Mari.

Note: You can toggle Color Management in the Project Settings Dialog. When Color Management is disabled, you can still enable the View Transform toolbar by clicking the / Color/Scalar icon.

Select a channel in the Channels Palette and use the toolbar to choose the view transform and edit the LUT etc. The color icon on the left is gray if the channel contains scalar data, otherwise it is color to indicate color data. (For a more detailed explanation, see Color Data and Scalar Data).

You can change the view transform's canvas colorspace using the dropdown list, and revert to the default colorspace using the reset button.
