IMAGES - Coggle Diagram

- - - - How made?
        ■ Make a bitmap from scratch with a paint or drawing program.
        ■ Grab a bitmap from an active computer screen with a screen capture program, and then paste it into a paint program or your application.
        ■ Capture a bitmap from a photo or other artwork using a scanner to digitize the image.
        ■ Once made, a bitmap can be copied, altered, e-mailed, and otherwise used in many creative ways.
      - You can get bitmaps from suppliers of clip art, and from photograph suppliers who have already digitized the images for you.
      - You can also download an image bitmap from a web site: in most browsers right-click over the image to see a menu of options.
      - Legal rights protecting
        use of images
        
        Public domain images were either never protected by a
        copyright or their copyright protection has ended.
        
        Generally these can be freely used without obtaining permission or paying a license fee, though there still may be an ownership issue for a particular work of art
        
        Royalty-free images are purchased and then used without paying additional license fees.
    - - Capturing and Editing Images
        
        The simplest way to capture what you see on the screen at any given moment is to press the proper keys on your computer keyboard.
        
        The way to get more creative power when manipulating bitmaps is to use an image-editing program, likely one of the programs named previously.
        
        Morphing is another effect that can be used to manipulate
        still images or to create interesting and often bizarre animated transformation.
      - Scanning Images
        
        Everyday objects can be scanned and manipulated using image-editing tools, such as those described in the preceding section, to create unusual, attention-getting effects.
        
        Another alternative to computer-generated graphics is to create artwork using traditional methods: watercolors, pastels, and even crayons.
        
        Powerful filters and plug-ins are offered by most image-editing programs (see illustration to right) to manipulate bitmaps in many different
        ways.
  - - - A vector is a line that is described by the location of its two endpoints.
      - Vector drawing uses Cartesian coordinates where a pair of numbers describes a point in two-dimensional space as the intersection of horizontal and vertical lines (the x and y axes).
  - - - autotracing: programs and utilities that will compute the bounds of a bitmapped image or the shapes of colors within an image and then derive the polygon object that describes the image.
- - - - a color is created by combining colored
        light sources in three primary colors: red, green, and blue (RGB).
      - This is the process used for cathode ray tube (CRT), liquid crystal (LCD), and plasma displays.
    - - color is created by combining colored media such as paints or ink that absorb (or subtract) some parts of the color spectrum of light and reflect the others back to the eye.
      - the process used to create color in printing: cyan, magenta, yellow and black (CYMK).
    - - Models or methodologies used to specify colors in computer terms are RGB, HSB, HSL, CMYK, CIE, and others.
      - Other color models include CIE, YIQ, YUV, and YCC. CIE describes color values in terms of frequency, saturation, and illuminance
