What is KTooN?

KTooN is a design or authoring tool for 2D Animation. 
It is free and open source software

Advantage of KTooN

•  It is an excellent tool for simple 2D animation
•  It is easy enough to get into
• The interface is intuitive enough that newcomers can pick it up and work it without too much trouble
•  It is a pretty lightweight package.

KTooN is free software under the GPL. While today it runs only on Linux, the developers have stated that they will develop versions for Windows and Mac OS X in the future. The community behind KToon is helpful. You can find discussion boards as well as fairly helpful tutorials and support, such as frequently asked questions and mailing lists, on the project's home page.

Bitmap vs Vector

Bitmap (or raster) images:

• are made up of pixel in a grid.
• what is pixel? a very small square that is assigned a color, and then arranged in a pattern to form the image. 
• when we zoom in on a bitmap image, we can see individual pixels that make up that image.
• resolution dependent. Resolution - refers to the number of pixels in an image and is usually stated as dpi (dot per inch) or ppi (pixel per inch)

Common bitmap formats include:
 
• BMP
• GIF
• JPEG, JPG
• PNG
• PCX
• TIFF
• PSD (Adobe Photoshop)

Popular bitmap editing programs are:
 
• Microsoft Paint
• Adobe Photoshop
• Corel Photo-Paint
• Corel Paint Shop Pro
• The GIMP

Key Points About Bitmap Images:
• pixels in a grid
• resolution dependent
• resizing reduces quality
• easily converted
• restricted to rectangle
• minimal support for transparency
  
Vector images:

• are not based on pixel patterns, but instead use mathematical formulas to draw lines and curves that can be combined to create an image from geometric objects such as circles and polygons
• can be manipulating the lines and curves that make up the image using a program such as Adobe Illustrator.
• resolution independent - because they can be output to the highest quality at any scale

Common vector formats:

• AI (Adobe Illustrator)
• CDR (CorelDRAW)
• CGM (Computer Graphics Metafile)
• SWF (Shockwave Flash)
• DXF (AutoCAD and other CAD software)

 
 Advantage of vector images:

• have much smaller size compare to bitmap (raster)
• A vector image just has to store the mathematical formulas that make up the image, which take up less space. 
• Vector images are also more scalable than bitmap images. When a vector image is scaled up, the image is redrawn using the mathematical formula. The resulting image is just as smooth as the original 

However, vector format are not well supported on the web. Currently, the only way vector images can be displayed on the Web is by requiring viewers to install a browser plug-in.

The two most popular image formats used on the Web, GIF and JPEG are bitmap formats. Most vector images must be converted into bitmap images (or rasterized) before they can be used on the web

INTRODUCTION TO MULTIMEDIA

What is Multimedia?

Multimedia is a combination of text, graphics, sound, animation and video that is delivered interactively to the user by electronic or digitally manipulated means.





ELEMENTS OF MULTIMEDIA


1. TEXT

• the most basic element of multimedia
• contains words to express something
• a good choice of words could help us to convey messages to the users
• normally used in contents, menus, navigational buttons  

# To produce an effective multimedia program, there are 3 things that need  to be considered:

• the position of the text on the screen
• the length of the message
• legibility of the text 

2. GRAPHIC/IMAGES

• two-dimensional figure or illustration
• could be produced manually (by drawing, painting, carving etc) or by computer graphics technology
• to show more clearly what a particular information is all about.
• for example: diagrams, pictures 

3. AUDIO

• produce by vibration, as perceived by the sense of hearing  
• audio could come in the form of speech, sound effects and music

4. ANIMATION

• is the process of making a static image look like it is moving
• animation is used to further enhance or enriched the experience of the user to further understand of information conveyed to them

5.  VIDEO

•  is the technology of capturing, recording, processing, transmitting and reconstructing moving pictures.
• video is more towards photo realistic image sequence/live recording as in comparison to animation
