Bitmap Image Editing B.Sc. (Hons) Multimedia ComputingMedia Technologies

Agenda Bitmapped Graphics Transformations Effects B.Sc. (Hons) Multimedia ComputingMedia Technologies

Bitmapped Graphics Allow for high-definition photorealistic images. Image encoded on a pixel by pixel basis. Image resolution degraded when scaled Supports lossless compressions algorithms File Formats -.BMP,.GIF,.JPG,.TIF.TGA Software Adobe Photoshop ( with ImageReady) Macromedia Fireworks PaintShop Pro (Shareware) B.Sc. (Hons) Multimedia ComputingMedia Technologies

True Colour Human eye can distinguish between 2 24 colours = colours Thus any system giving >= 2 24 colours can be described as ‘Truecolour’ or Truecolor 24 bits per pixel yields true colour 16 bits per pixel often referred to as ‘High Colour’ B.Sc. (Hons) Multimedia ComputingMedia Technologies
