Study Notes
Creation of Multimedia Images
- Before creating images in multimedia, plan your approach using flow charts and storyboards, organize available tools, and prepare devices and workspace.
- Still images are a crucial element of a multimedia project, and their type depends on display resolution.
Bitmap Images
- Bitmaps are suited for creating photo-realistic images and are a simple matrix of tiny dots that form an image.
- Bitmapped images can have varying bit and color depths and are made up of individual dots or picture elements known as pixels or pels.
- Bitmaps can be sourced from clip art galleries, bitmap software, capturing and editing images, and scanning images.
Vector Images
- Vector graphics can be scaled to any desired size without pixelation.
- Vector-drawn objects are not easily scalable and resizable, unlike bitmap images.
- Vector images require a plug-in for web-based display, unlike bitmap images.
3-D Drawing and Rendering
- 3-D applications provide x, y, and z axes and adjustable perspective views.
- 3-D animation tools include modeling, extrusion, lathing, rendering, and panormas.
- Rendering uses intricate algorithms to apply user-specified effects, including Gouraud shading, flat shading, and Phong shading.
Colors and Palettes in Multimedia
- Color is the frequency of a light wave within the narrow band of the electromagnetic spectrum, to which the human eye responds.
- The eye can differentiate among about 80,000 colors, or hues, consisting of combinations of red, green, and blue.
Computerized Colors
- Additive color combines colored light sources in three primary colors - red, green, and blue (RGB) for TV and computer monitors.
- Subtractive color combines colored media such as paints or ink, absorbing some parts of the color spectrum and reflecting others back to the eye.
- Monitor-specific colors should be used according to the target audience’s monitor specifications.
- Color models include RGB, HSB, HSL, CMYK, CIE, YIQ, YUV, and YCC.
Color Palettes
- Color palettes are mathematical tables that define the color of pixels displayed on the screen.
- Dithering is a process whereby the color value of each pixel is changed to the closest matching color value in the target palette.
