Channel Presets Dialog

The Channel Presets dialog is described below with functions for how to access it. A list of the controls on the dialog can be found in the table below.

What It Does

Allows you to set up preferences for quickly creating channels through the Channels palette or menu. These presets include options such as the color depth size, patch size, file space, and colorspace. This gives you the opportunity to quickly set up a channel template for channel types you know are going to be created numerous times. You can also choose from a few Mari channel presets.
