Dedicated Vector and Bitmap editing software.

Software is the term used to describe the programs that run on a computer. There are many types of application that can be used to create, manipulate and view digital graphics.

Vector Graphics Vector graphics define objects as coordinate points and use mathematics inside the software to calculate how to display the image onto the screen or printer.

Each object has an outline and / or fill Objects may be grouped together. Vector graphics are very good for diagrams / logo’s Corel Draw / Fireworks / AutoCAD / Microsoft Visio.

Vector Graphics Vector graphics are different from Bitmap graphics. The main features are: Small file size when saved to disk No loss of print quality when enlarged or reduced in size Vector pictures are made from objects such as circles and rectangles.

Bitmap Graphics Bitmap graphics are made from lots of pixels, each with a colour. They are also known as raster graphics.

Bitmap graphics are different from Vector graphics Bitmap graphics are different from Vector graphics. The main features of bitmaps are: Large file size when saved to disk Print quality can become blocky when enlarged or reduced in size.

Bitmaps can be created when a picture is scanned into a computer or from a digital camera. Bitmap graphics are very good for screenshots and web page illustrations. Paint ShopPro / Paint

Dedicated Photo Manipulation Photo manipulation software applications are specialist bitmap programs that are very good for manipulating photographs Corel PHOTO-PAINT / Adobe Photoshop

Graphics facilities embedded within other application packages. Many applications have a graphical capabilities built into them. Word is a word processing application that also has graphical features allowing you to easily include photographs and other digital graphics in a document.

Task Explain the difference between: Vector graphics software such as Corel Draw. Bitmap software such as paint. Photo manipulation software such as Adobe Photoshop. Word Comment on their limitations and what they are best suited to.
