Saving web graphics (GIF/JPEG) For saving graphics in GIF and JPEG formats (the standard web image formats), Canvas provides an integrated dialog box. You can select either format and use multiple preview panes to compare how the format and other settings will affect your images before saving. GIF format    GIF is the best format for graphics that contain a small number of colors, such as vector art with flat colors. GIF format sup- ports Black & White, Grayscale and Indexed color images, with 1 to 8 bits of color data for a maximum of 256 colors. JPEG format    JPEG format provides compression of high resolu- tion, full-color (24- bit) RGB images. JPEG is designed for efficient storage of continuous-tone images such as photographs. “JPEG” is an abbreviation of “Joint Photographic Experts Group,” a standards organization that promoted the format. To save graphics in GIF or JPEG format 1 Select the objects to save, or Canvas will save the current doc- ument page. Choose File > Save As. 2 In the directory dialog box, select GIF/JPEG in the file format pop-up menu. Type a name for the file and select the save location. •   To save only the selected objects, click Save Selection. •   To save the file on the Internet, see “Internet file exchange (Windows)” on page 13.149. 3 Click Save. 4 Unless you are saving a single paint object, the Render Image dialog box appears. Select rendering options and click OK. For more information, see “Rendering images” on page 13.147. 5 The Export Preview dialog box appears. Use the dialog box to select the format and other options for saving the graphic. For com- plete instructions, see “Export Preview options” on page 13.162. 6 Click Export to save the file. Exporting images in GIF or JPEG format Exporting lets you save selected images, but not entire documents. The difference between Save As and Export is that Save As will ren- der objects or an entire document to create an image that can be saved. Export will save only a single paint object, without rendering. Tip You can use a wizard to save graphics for the web. Select the images you want to save, and choose File > Save to Web. The wizard will help you save images in GIF and JPEG formats.
