Unit 7: Multimedia Software Tools

• Windows: Allows you to edit two or more documents at the same time. Each document notes
appears in a separate window. This is particularly valuable when working on a large project
that consists of several different files.
• WysiWyG (what you see is what you get): With WYSIWYG, a document appears on the
display screen exactly as it will look when printed.
The line dividing word processors from desktop publishing systems is constantly shifting. In
general, though, desktop publishing applications support finer control over layout, and more
support for full-colour documents.

Electric Pencil, released in December 1976, was the first word processor
software for microcomputers.

7.2 oCr software

It stands for “Optical Character Recognition”. This technology is what allows you to scan that
paper you lost on your hard drive, but fortunately printed out, back into your computer. When
a page of text is scanned into a computer without OCR software, all the computer sees is a bunch
graphical bits, or an image. In other words, it has no idea that there is text on the page, much less
what the text says. However, an OCR program can convert the characters on the page into a text
document that can be read by a word processing program. More advanced OCR programs can
even keep the formatting of the document in the conversion.
Often there will be multimedia content and other text to incorporate into a multimedia project,
but no electronic text file. With optical character recognition (OCR) software, a flat-bed scanner,
and a computer, it is possible to save many hours of rekeying printed words, and get the job done
faster and more accurately than a roomful of typists.
The OCR software turns bitmapped characters into electronically recognizable ASCII text. A
scanner is typically used to create the bitmap. Then the software breaks the bitmap into chunks
according to whether it contains text or graphics, by examining the texture and density of areas
of the bitmap and by detecting edges. The text areas of the image are then converted to ASCII
character using probability and expert system algorithms.

7.2.1 types of oCr software
There are the following types of OCR software available:

Desktop and server oCr software
OCR software and ICR (Intelligent Character Recognition) software technologies are analytical
artificial intelligence systems that consider sequences of characters rather than whole words or
phrases. Based on the analysis of sequential lines and curves, OCR and ICR make ‘best guesses’
at characters using database look-up tables to closely associate or match the strings of characters
that form words.

With IT technology development, the platform for people to use software has been changed
from single PC platform to multi-platforms such as PC +Web-based+ Cloud Computing +
Mobile devices. After 30 years development, OCR software started to adapt to new application
requirements. WebOCR also known as OnlineOCR or Web-based OCR service has been a new
