SCT (.sct)

Background & Context

    • Scitex CT format.
    • Raster image file format.
    • Used for pre-press imaging applications.
    • SCT is an acronym for Scitex Continuous Tone.
    • Binary format.
    • Stores images as RGB, CMYK, or grayscale bitmaps at a resolution of 8 bits per channel.
    • Does not support alpha channels.
    • Developed and maintained by HP Scitex.

Import & Export

  • Import["file.sct"] imports an SCT file and returns an image.
  • Import["file.sct",elem] imports the specified element from an SCT file.
  • The import format can be specified with Import["file","SCT"] or Import["file",{"SCT",elem,}].
  • Export["file.sct",expr] exports graphics or any other expression as an image to an SCT file.
  • When exporting Wolfram Language graphics or arbitrary expressions to SCT, the resulting image has the same raster size as its displayed form.
  • Image objects are by default exported at their raster size.
  • Because SCT is a raster image format, all fonts are rasterized on export.
  • See the following reference pages for full general information:
  • Import, Exportimport from or export to a file
    CloudImport, CloudExportimport from or export to a cloud object
    ImportString, ExportStringimport from or export to a string
    ImportByteArray, ExportByteArrayimport from or export to a byte array

Import Elements

  • General Import elements:
  • "Elements" list of elements and options available in this file
    "Summary"summary of the file
    "Rules"list of rules for all available elements
  • Data representation elements:
  • "Data"array of color values
    "Graphics"Graphics object representing an image
    "Image"raster image, given as an Image object
  • Import and Export by default use the "Image" element for SCT files.
  • Advanced Import elements:
  • "BitDepth"number of bits used to represent each color channel
    "Channels"the number of color channels used in the file
    "ColorSpace"color encoding used in the file
    "ImageResolution"image resolution specified in the file
    "ImageSize"raster dimensions
    "Summary"summary of the file
