virus checkers - power saving programs etc. 2. VECTOR GRAPHICS These are pictures defined by geometrical shapes and formulas instead of maps of bits. i.e. the computer stores only the instructions (how to draw the shapes that make up the picture). go to point A, at coordinate (X1,Y1) draw line from point A to point B, at coordinate (X2, Y2) OR go to point A, at coordinate (X,Y) draw square of width B fill with color C Common vector graphics file formats: WMF(Microsoft Windows Metafiles) , CDR (Corel Draw), 3DS (AutoDesk 3D Studio), AI (Adobe Illustrator) VRML (Virtual Reality Modeling Language) is an Internet 3D graphics language. It has now been superceeded by X3D and now supported by the Web3D Consortium (previously vrml.org There is a huge difference in file sizes between vector and bitmap graphics ADVANTAGES AND DISADVANTAGES of the two formats VECTORS BITMAPS • Small size quality Better colours - better photo-realistic • Fast transmission Faster drawing on slow processors • Scalability • 3-D Exercise: think of USES of the two file formats IMAGE COMPRESSION There is a need to use bitmap images - vector graphics alone are not sufficient. Therefore, we need to compress bitmap images to make them smaller (in file size) so that they can be transmitted faster. Compression: Reduces the amount of
