Desktop Publishing

Hi! I'm going to talk about Desktop Publishing

Desktop publishing combines apersonal computer and WYSIWYG page layoutsoftware to create publicationdocuments on a computer for either large scale publishing or small scale local multifunction peripheral output and distribution.

The term "desktop publishing" is commonly used to describe page layout skills.

The skills and software are not limited to paper and book publishing. The same skills and software are often used to create graphics for point of sale displays,promotional items, trade show exhibits, retail package designs and outdoor signs

A particularly important feature of desktop publishing systems is that they enable you to see on the display screen exactly how the document will appear when printed.

What is a "page layout" program? It is a program that enables you to format pages of text andgraphics.

4- What is the difference between vector and bitmap images?

A vector image uses geometrical formulas to represent images. The other way of representing graphical images is through bit-maps in which the image is made up of a pattern of dots (note that bit-maps are often referred to as raster graphics). Programs that allow you to create and manipulate vector graphics are called draw programs and programs that manipulate bit-map images are called paint programs.

Vector graphics are more flexible than bit-maps because they can be easily re-sized. In addition, images stored as vectors look better when displayed on high resolution printers and monitors. Bit-map images look the same, regardless of the resolution of the display. Another advantage of a vector graphic is that they often require less memory than bit-maps do.

What does PDF mean and why is it useful? (portable document format)

It is an adobe file extension, and is a fairly standard file extension for exchanging documents due to the fact that the program that reads these files is free.
