Vector Graphics § Vector graphics are created from mathematical formulas used to define lines, shapes and curves. § Edited in draw programs § Shapes can be edited by moving points called nodes (drawing points) Node Handle

Examples Original Image Resized Image § More examples § http: //qvectors. com/ Shapes that make up the image.

Uses of Vector Graphics § Graphics that will be scaled (or resized) § Architectural drawings and CAD programs § Flow charts § Logos that will be scaled (resized) § Cartoons and clip art § Graphics on websites § Because they have very small file sizes. § This allows them to load quickly. § Fonts and specialized text effects

Advantages of Vectors § Resolution Independent § Regardless of how much the image is enlarged or reduced, the image definition and quality remain the same. § Small File Sizes § Easily transferred over the Internet.

Disadvantages of Vectors § Lower color quality than raster images. § They do not support as many colors. § Not good for photographic images. § Click to see an example.

Popular Vector Graphic Software § § Xara Xtreme Adobe Illustrator Corel. Draw Inkscape – open source software similar to Adobe Illustrator.

§ Common Vector File Formats § AI – Adobe Illustrator § Industry standard used by developers of vector graphics. § Used to create, save, and archive original artwork. § EPS – Encapsulated Postscript § Meta Graphic § Graphics developers generally save a copy of the AI file in EPS format because it can be opened by computers running different operating systems. § Preferred format for vendors/clients who use the graphics in publications due to its portability.

Meta Graphics § Can contain vector and raster data. § Shapes in vector graphics can be filled with textures and patterns that are raster graphics. § Useful when layering text on top of raster graphics. § Examples § WMF – Windows Metafile § EPS – Encapsulated Postscript

More Vector Formats § SVG – Scalable Vector Graphics § Standard format created by W 3 C § Versatile, all-purpose vector format § PLT – Hewlett Packard Graphics Language Plot File § CDR – Corel Draw § DXF – Auto. CAD § WMF – Windows Metafile
