Notes

• iPhoto is part of iLife, which includes a DVD authoring package (iDVD), a video editor (iMovie), a music player (iTunes), a multimedia web publisher (iWeb), and an audio-sequencing program (GarageBand).
• FastPictureViewer's DirectX hardware acceleration support depends on the actual video card installed and the amount of available video memory. The commercial version also supports previewing some camera RAW formats for which a WIC-enabled codec exists. Such RAW codecs are currently available from Canon, Nikon, Olympus, Pentax, Sony and for Adobe DNG.
• Many applications on Mac OS X use either the Core Image or QuickTime APIs for image support. This enables reading and writing to a variety of formats, including JPEG, JPEG2000, Apple Icon Image format, TIFF, PNG, PDF, BMP and more.
• SView5 may also run on Linux/x86 and MacOS/x86 using Mono.
