File Types There are many kinds of graphics file formats and this is a specialised area and a bit complicated. Examples : bmp GIF JPEG TIFF PICT Raw For most applications involving photographic images, use the JPEG file format (Joint Photographic Experts Group) For graphics or paint type files use GIFs (Graphical Interchange Format) 12CS1354-GRAPHICS & MULTIMEDIA
