SCT (.sct)

BackgroundBackground

    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 and ExportImport and Export

  • Import["file.sct"] imports an SCT file and returns an image.
  • 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.
  • Import["file.sct",elem] imports the specified element from an SCT file.
  • Import["file.sct",{elem,suba,subb,}] imports a subelement.
  • Import["file.sct",{{elem1,elem2,}}] imports multiple elements.
  • The import format can be specified with Import["file","SCT"] or Import["file",{"SCT",elem,}].
  • Export["file.sct",expr,elem] creates an SCT file by treating expr as specifying element elem.
  • Export["file.sct",{expr1,expr2,},{{elem1,elem2,}}] treats each as specifying the corresponding .
  • Export["file.sct",expr,opt1->val1,] exports expr with the specified option elements taken to have the specified values.
  • Export["file.sct",{elem1->expr1,elem2->expr2,},"Rules"] uses rules to specify the elements to be exported.
  • See the reference pages for full general information on Import and Export.
  • ImportString and ExportString support the SCT format.

ElementsElements

  • General Import elements:
  • "Elements" list of elements and options available in this file
    "Rules"full list of rules for each element and option
    "Options"list of rules for options, properties, and settings
  • Data representation elements:
  • "Data"array of color values
    "Graphics"Graphics object representing an image
    "GrayLevels"array of normalized gray-level values
    "Image"raster image, given as an Image object
    "RGBColorArray"array of RGBColor objects
  • Import and Export by default use the element for SCT files.
  • Advanced Import elements:
  • "BitDepth"number of bits used to represent each color channel
    "ColorSpace"color encoding used in the file
    "ImageResolution"image resolution specified in the file
    "ImageSize"raster dimensions
