  16. Difference Between Bitmaps and Vector Graphics - Have you wondered why some pictures show jaggies on the edges when they are resized larger. Or why some pictures don't show jaggies when enlarged? Figures 1 and 2 show how they differ.

  17. Types of computer graphics There are two types of computer graphics— 1) Bitmaps and 2) Vector graphics. 1- Bitmap graphics get the jaggies when they are resized. 2- Vector graphics can be resized to any extent without the pixelated jaggies.

  18. Difference Between Bitmaps and Vector Graphics 1- Bitmap graphics are made up of group of small dots called pixels. 2- Vector graphics are made up of lines, curves, and fills. 3- Bitmap graphics, also known as "raster graphics," are composed of very small dots of the same or different color that are placed so closely to each other that the human eye perceives them not as dots, but as a picture--for example, a photograph.

  19. 4- All photographs from digital cameras or scans made into the computer from a scanner are bitmaps--and they are all entirely composed of these pixel dots. 5- Bitmaps can also be designs created from scratch in an image editor and paint program. 6- Each bitmap has a fixed size-- resize it larger and graphic

  20. Vector graphics • Vector graphics don't look like photographs at all. • In fact, they look more like illustrations--for example, a logo. • Vector graphics are also known as "object-oriented" or " drawing" graphics. • Rather than a collection of dots, vector graphics are a collection of graphic elements like lines, squares, rectangles, or circles.

  21. Each element in a vector graphic has its own coordinates that be manipulated and resized individually without distortion since the computer just increases the coordinate values proportionately. • Fortunately, these resizing manipulations don't effect the quality of a vector graphic.

  22. File Formats • Here are some of the common file formats in the graphic design world • Common bitmap file formats include • BMP - Windows Bitmap • JPEG - Also known as JPG • JPEG 2000 - A higher quality variant of JPEG • TIFF - Used mainly in the print industry

  23. GIF - Used as web graphics and also has an animated variant. • TGA - Targa, an old bitmap format, not too common these days • PNG - An efficient file format that was supposed to replace GIF • PSD - The native file format of Adobe Photoshop, the most omnipresent • image editor on the planet • PICT - A Macintosh bitmap format • c

  24. Common vector graphics file formats • EPS - Encapsulated PostScript, an industry vector standard • WMF - Windows Metafile • EMF - Enhanced Windows Metafile • AI - The Adobe Illustrator file format • CDR - The CorelDRAW file format

  25. WPG - The WordPerfect Graphic file format, not too common these days. • SWF - Actually, an animation format that uses vectors. • SVG - Scalable Vector Graphic

  26. Converting File Formats • Conversions between file formats are commonplace, although these conversions are mainly successful only between bitmaps and bitmaps (or between vectors and vectors). • Vector to bitmap conversions are also common, but the other way round is not too common

  27. --mainly because it's not possible unless you use a tracing program like Adobe Streamline or CorelTRACE • --and even then, results are time-consuming and not too great unless you are ready to spend time and experiment with the results.

  28. Bitmap Programs • Adobe Photoshop, and Adobe Photoshop Elements • Macromedia Fireworks (acquired by Adobe) • Corel Paint Shop Pro, PHOTOPAINT, and Painter • Microsoft Digital Image Pro • Ulead PhotoImpact • IrfanView

  29. Vector Graphics Programs • Adobe Illustrator, and Freehand (acquired from Macromedia) • CorelDRAW • Microsoft Expression • Xara Xtreme • Macromedia Flash (acquired by Adobe)
