How to Do Everything With Your Scanner- P32: My thanks to the terrifically creative and knowledgeable staff at Osborne, particularly acquisitions editor Megg Bonar and acquisitions coordinator Alissa Larson for their responsiveness and flexibility. Special thanks to technical editor Steve Bain, not only for his insight and attentiveness to accuracy, but also for actively coming up with many ideas for content. | CHAPTER 8 Formats for Saving and Storing Files 139 Choosing the Right File Format Choosing the right file format is a tradeoff between image size quality and compatibility with other programs. The BMP format for example is compatible with all Windowsbased programs but it is an unwieldy format for sending photos by email because it does not allow for data compression. Similarly TIF is an excellent format since it uses a lossless compression scheme. It s the format I used to produce and submit most of the images that appear in this book. Your friends however might balk at downloading TIF-sized files which are only slightly smaller than the BMP variety. JPEG GIF and PNG formats are convenient for sending and downloading images but the compression schemes they use result in data loss that might or might not be apparent over time. All in all the format you choose depends on whether you ll be sending the format over the Internet and to what extent you re concerned with data loss. 8 This page intentionally left blank.
