Chapter 4 : IMAGES

1. Vector drawing

1.1. vector drawn images versus bitmaps

1.1.1. vector images use less memory space and have smaller file size

1.1.2. vector objects are easily scalable without loss of resolution or image quality

1.1.3. vector images cannot be used for photorealistic image

1.1.4. bitmaps are not easily scalable and resizable

1.1.5. bitmaps can be converted to vector images using autotracing

2. 3-D drawing and rendering

2.1. features of a 3-D application

2.1.1. modeling

2.1.2. extrusion

2.1.3. lathing

2.2. Rending - use of intricate algorithms to apply user-specified effects and take many hours for a single image

3. Colors and palettes in multimedia

3.1. understanding natural light and color

3.1.1. additive color

3.1.2. subtractive color

3.1.3. color models

3.2. color palettes

3.3. additive color

3.4. subtractive color

3.5. dithering

4. Making still images

4.1. bitmap editors-painting program

4.1.1. bitmap is a data matrix that describes the characteristics of all the pixels making up an image

4.2. vector editors-drawing program

4.3. capturing and editing images

4.4. users can scan images from conventional sources and make necessary alterations and manipulations

5. Bitmap sources

5.1. where do bitmaps come from?

5.1.1. capture a bitmap using a camera

5.1.2. from a photo

5.1.3. grab from an active computer screen

5.1.4. get from the suppliers of clip arts
