UnsignedInteger24

  • Import can read any file as a sequence of unsigned 24-bit integers.
  • Export writes a list of integers in the range to a binary file.

Background & Context

    • Sequence of unsigned 24-bit integers.
    • Raw binary format.
    • Equivalent to the Byte format.

Import & Export

  • Import["file","UnsignedInteger24"] imports any file, returning a packed array of integers in the range .
  • Export["file",list,"UnsignedInteger24"] exports a list of integers in the range to file.
  • Import["file",{"UnsignedInteger24",elem}] or Import["file",elem ] imports the specified element from file.
  • Import["file",{"UnsignedInteger24",{elem1,elem2,…}}] imports multiple elements.
  • 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 element:
  • "Data"list of integers in the range
  • By default, Import and Export use the "Data" element.
  • Import["file",{"UnsignedInteger24",n}] gives the n^(th) 24-bit integer from file.
  • Trailing bytes are ignored if the size of the imported file is not a multiple of the data size.

Basic Examples  (1)

Export a list of integers to a binary 24-bit representation:

In the previous output, each integer is represented by a sequence of 3 bytes:

Convert the binary data back to a list of integers:

Numbers outside the range cannot be converted to the UnsignedInteger24 format:
