Transcript of "Definitions"

  1. 2. Vector and Rector Images . Vector graphics is the use of geometrical primitives such as points,lines,curves, and shapes or polygons which are all based on mathematical equations, to represent images in computer graphics. A raster graphic (bit-map) is a data structure representing a generally rectangular grid of pixels, or points of colour viewable via a monitor, paper or other display medium. A raster graphic A vector graphic
  2. 3. HA1 - Technical File – Carrie Deans. Antialiasing Anti-Aliasing is a method of tricking the eye that a jagged edge is really smooth. Anti-Aliasing is often referred in games and on graphics cards. In games especially the chance to smooth edges of the images goes a long way to creating a realistic 3D image on the screen.
  3. 4. HA1 - Technical File – Carrie Deans. Image resolution describes the detail an image holds. The term applies to raster digital images, film images, and other types of images. Higher resolution means more image detail. Resolution                        Image at left has a higher pixel count than the one to the right, but is still of worse spatial resolution Image on the right has higher resolution than the image on the left.
  4. 5. HA1 - Technical File – Carrie Deans. Aspect Ratio The aspect ratio of an image is the ratio of the width of the image to its height, expressed as two numbers separated by a colon. The most common aspect ratios used today in the presentation of films in movie theaters are 1.85:1 and 2.39:1. Two common videographic aspect ratios are 4:3 (1.33:1), the universal video format of the 20th century and ; 16:9 (1.77:1), universal for high-definition television and European digital television.
  5. 6. HA1 - Technical File – Carrie Deans. File Formats. A file format is a particular way that information is encoded for storage in a computer file. For Example- Gif, Jpeg, Tiff, Eps, PSD and PDF. A Gif is a Graphics Interchange Format - Images using a fixed colour palette. The GIF format uses compression for smaller files and faster downloads. This format is best for images with solid colours or areas of uniform colour such as illustrations and logos. A Jpeg JPEG - Joint Photographic Experts Group - Used for photographic images. Unlike GIF files the JPEG format can take advantage of the full spectrum of colours.
  6. 7. HA1 - Technical File – Carrie Deans. Colour models- A color model is an abstract mathematical model describing the way colours can be represented as tuplesof numbers, typically as three or four values or colours components. The different colour formats are RGB and CMYK. RGB is an Additive colour model For computer displays Uses light to display colour Colours result from transmitted light Red+Green+Blue=White. CMYK is an Subtractive colour model For printed material Uses ink to display colour Colours result from reflected light Cyan+Magenta+Yellow=Black RGB COLOUR MODEL. CMYK COLOUR MODEL.
  7. 8. HA1 - Technical File – Carrie Deans. Adobe Photoshop Adobe Photoshop is a graphics editing program developed and published by Adobe Systems Incorporated. Some of its features include: Crop an image, Moving an image on to the background of another image, changing the colours of an image and changing the shape and size of an image.
  8. 9. HA1 - Technical File – Carrie Deans. Adobe Illustrator Adobe Illustrator is a vector graphics editor developed and marketed by Adobe Systems. Illustrator is similar in scope, intended market, and functionality to its competitors, CorelDraw and Macromedia FreeHand.
  9. 10. HA1 - Technical File – Carrie Deans. Adobe InDesign Adobe InDesign is a software application produced by Adobe Systems. It can be used to create works such as posters, flyers, brochures, magazines, newspapers and books
