Alpha Channels | 567

3 With the New Channel from Color Range dialog box open, click in the document window to pick a

color.

4 The color you select is the middle of the range of colors used to create the channel.

5 In the New Channel from Color Range dialog box, adjust the Range slider in the Hue, Saturation, and

Value areas.

These sliders control the selected range. You can drag the limits of the range in either direction.

6 In the New Channel from Color Range dialog box, adjust the Feather slider in the Hue, Saturation,

and Value areas.

This helps soften the edges of the channel.

If you want to invert the channel, enable the Inverted check box.

The channel displays as a red overlay on the image in the Preview window of the New Channel

from Color Range dialog box. You can drag in the Preview window to display other parts of the

image.

Importing and exporting alpha channels

When you save a file to the Corel Painter file format (RIFF), the alpha channels that are stored in the file are

retained. They are also retained when exporting Corel Painter files in the Adobe Photoshop (PSD) format.

In addition, if you import an Adobe Photoshop file that contains alpha channels in Corel Painter, the alpha

channels are supported.

It is important to note that when you open RGB-based Adobe Photoshop files in Corel Painter, anything in

the alpha channels (4 and above) appear as a channel in Corel Painter. Conversely, when you export your

Corel Painter file in the Photoshop format, all channels are placed into channels 4 and above.

Selecting and viewing channels

You can select and view all alpha channels that are stored in the active document from the Channels panel.

Selecting and viewing a channel are distinct operations — you can view a channel without selecting it, and

you can select a channel without viewing it. If you want to edit a particular channel, you must select it.
