Clearing and copying a selection You can replace the pixels in a selection with the current background color by pressing the Delete key, or by choosing Cut in the Edit menu. (The Cut command also transfers the selection to the Clip- board.) Canvas replaces the selected pixels with the color currently displayed in the background color icon. Keep in mind that “deleting” a selection doesn’t leave a hole or transparent area in the paint object, unless the paint object has a visibility mask, as described later in this chapter. To place a copy of a selection on the Clipboard without clearing the area in the original image, choose Edit > Copy. When a selection has been placed on the Clipboard, you can paste it into another paint object in edit mode, where it will become a floating selection, or paste it into the document to create a new paint object. Feathering the edges of a selection You can feather (soften) the edges of a selection so that it blends more naturally into the original image. You can use the Feather com- mand to soften the hard edge of a selection and spread the selection over a larger area. 1 With a paint object in edit mode, make a selection and choose Image > Select > Feather. 2 In the Feather dialog box, enter the number of pixels to feather the selection in the Radius text box. The larger the Radius value, the more Canvas softens the selection edge. 3 Click OK to feather the selection. Pasting into selections The Paste Into command pastes the Clipboard contents into a selec- tion in an image. This includes a selection in an image channel or a channel mask attached to an object. The Paste Into command pastes anything that you copy to the Clip- board, including a vector, text, or paint object, an image selection, or a segment of a vector object. You can use Paste Into to composite images and create effects that would otherwise be difficult to produce. For example, to simulate a picture on a television screen in a photograph, you can select the Tip If you want Canvas to recall a selection, be sure to save it before leaving edit mode. See “Saving and loading selections in channels” on page 33.667.
