CHAPTER 31 PAINTING AND IMAGE-EDITING Canvas provides a full palette of painting tools, including the digital equivalents of markers, airbrushes, and paintbrushes, plus tools for creating effects like neon and blends. The toolbar of painting tools also provides tools to select, retouch, color-correct, and clone images. This chapter explains how to use these painting tools, choose image modes, and convert objects into images. Paint objects and images A paint object is a special type of Canvas object that contains an image. Paint objects are always rectangular and are the same size as the images they contain. An image is a picture made up of many tiny squares, called pixels. A scanned photo, a TIFF or Photoshop (.PSD) file, and a picture you paint in Canvas are examples of images. Each pixel in an image is a solid color. Pixels can also be semi-trans- parent or completely clear. You can adjust the color, opacity, and transparency of pixels by using painting tools and commands. At the object level, you can use tools and commands such as the Selection tool and Align command to affect entire paint objects. Almost anything you can do to objects, you can do to paint objects. About paint objects and images in Canvas “Images” are pictures defined by tiny dots, called pixels. A scanned photo, a TIFF or Pho- toshop file, and pictures you paint in Canvas are all images composed of pixels. In a Canvas document, an image is contained in a paint object the same size as the image. Painting tools operate on the pixels within images, while object tools and com- mands, such as the Selection tool or Align command, apply to entire paint objects. You can perform common object operations, including move, copy, and duplicate, on paint objects. For details, see the chapter titled “Working with objects” on page 16.245. You can create images entirely in Canvas by making a new paint object that you can paint in, or creating an image from vector or text objects, as described in this chapter. You can also import images into Canvas documents using the following methods: •   Place an existing image in a document using the Place, Paste, or Acquire commands. •   Scan a photo using the Acquire command. See “Using scanners to acquire images” on page 32.633.
