View Controls

The channel view buttons can be used to switch between displaying the Red, Green, BlueAlpha, and Luma channels in the Preview Area.
You can view a particular channel by clicking the icon for it. You can also right click any of channel icons and choose which channels to be displayed from a menu.


Channel icons are toggles, which means that switching to the Alpha channel, for example, only displays the alpha, but clicking the Alpha icon again returns the original RGB channel display.
You can right-click and choose which channel should be hidden to combine multiple individual channels for display.





The utilities can be used to quickly control the safe area and background of the Preview Area and also give access to some caching options and other utilities.
