Image Compression in ShareScan 5.x

Everything you wanted to know about Image Compression in ShareScan 5.x

The following Compression options exist in ShareScan.

  • Medium:
    • Best picture and graphics quality
    • Minimal compression, single layer.
    • Mixed Raster Content (MRC) is not used.
    • DPI is not decreased. Used for best quality.
  • High:
    • In BW mode MRC is not used DPI is not decreased.
    • GrayScale and Color modes, MRC compression is used using decreased DPI.
    • JPEG is used for color images
    • TIFF G4 is used for BW images.
    • Results in smaller files than Medium compression, balancing size, quality, speed and performance.
  • Expert:
    • In BW mode MRC is not used, DPI is not decreased.
    • GrayScale and Color modes, MRC compression is used using decreased DPI.
    • JPEG2000 is used for color images,
    • JBIG2 is used for BW images.
    • Even smarter and more aggressive compression, in average decreases the size by roughly 30%, but also decreases the speed of compression.
  • Custom: (ShareScan 5.2 SP2 and later)
    • Color and Grayscale Image compression can be selected (JPEG vs. JPEG2000)
    • Image compression can be selected via slider (100 is best quality and biggest file size)
    • B&W compression can be selected
      • TIFF G4 - lossless, larger files, faster processing
      • JBIG2 - lossless, smaller files, slower processing
