My notes

  • All computer docs or files are packaged in different formats
  • format of the file usually defined by the files origin
  • compression of files throws away uneeded data

  • 2 categories of compression, lossy and lossless
  • lossy makes it poor quality
  • lossless makes image HQ but is larger file

  • TIF tag image format. for HQ printing. common format for desktop publishing, printing, photo and graphic design. not internet friendly. contains lossless for max quality
  • JPG image compression scheme mad for photographs. lossy format. can reduce file size to 10th of original without reducing quality too much. only works with photos, not for graphic images
  • GIF graphic interchange format. made for flat color in image. reduces image size by indexing color for 3-1 channels. contains no dots per inch(dpi) for printing.
  • PNG is common web format HQ. Can have alpha (transparency) panel. you can make shapes out of documents
  • Tif and jpg are best for images with pixels that blend in color call “contiguous pixels”
  • gif is best for images with flat even tone or “non-contiguous pixels”
