(II) JPEG –Lossy format Can reduce the quality of image –Does not handle sharp edges and abrupt changes well –Both GIF and JPEG share interlacing (GIF terminology) or progressive encoding (JPEG terminology) Downloads a rough whole image and gradually increases clarity Do not place too may interlaced images on a Web page –Slow the rendering of a page Save Options: Interlacing/Progressive Encoding

 2000 Deitel & Associates, Inc. All rights reserved. 5.3 File Formats: GIF or JPEG? (III) –JPEG format has scalable compression In Save Options dialog, Compression slider –Sliding to the left causes the image to retain high quality, but file size also high –Sliding to the right causes file size to decrease, but image quality suffers PNG (Portable Network Graphics) format –Can encode in RGBA A for alpha transparency –Makes images transparent against any background –Supported by Paint Shop Pro, Netscape Navigator, Internet Explorer –
