Internet protocols You can use the two major Internet protocols in Canvas for saving and uploading files, and for downloading (opening) files. To save or download files over the Internet, you need to know the address of the web or FTP site you want to access. Internet addresses are called Uniform Resource Locators (URLs). Downloading files You can use the Internet button to download files from File Transfer Protocol (FTP) sites, and from Web sites, which use Hypertext Transport Protocol (HTTP) (see “ftp://” on page 14.180 and “http://” on page 14.180). To download web images, you need to know the web page URLs and the image file names. You can open web images in JPEG and GIF files. From FTP sites, you can open most file formats that Canvas supports. Canvas down- loads and imports a file into the current document if you use Place or Acquire. If you use Open, Canvas opens the file in a new document. Saving files You can use the Internet button to save and upload files to FTP sites. Web (HTTP) sites do not support uploading. Instead, to post files for web pages, you upload the files to an FTP site. If you have a web site hosted by an Internet Service Provider (ISP), the ISP will tell you the FTP address and the path to use for storing you web files. Then you can use Canvas to save and upload web pages to your web site. You can save and upload all file types supported by Canvas. This includes web pages and image files for web pages. You can use File > Save As for all file formats, or use Image > Export for image for- mats. You can save web pages in HTML format or save images in GIF or JPEG format using the File > Save to Web wizard. For more information on web formats, see “Web publishing,” page 14.179. When you use the Internet button for saving files, Canvas saves a file in the format you specify and uploads the file to a location you spec- ify. Canvas does not save a local copy of the file. It’s always a good idea to save your work in a Canvas file so you can edit it later.
