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.

BackgroundBackground

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

Import and ExportImport and 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 reference pages for full general information on Import and Export.
  • ImportString and ExportString support the UnsignedInteger24 format.

ElementsElements

  • General Import elements:
  • "Elements" elements and options available in this file
    "Rules"full rules for each element and option
    "Options"rules for options, properties, and settings
  • Data representation element:
  • "Data"list of integers in the range
  • By default, Import and Export use the 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.

OptionsOptions

  • General option:
  • ByteOrdering-1what byte ordering to use
  • Import option:
  • "HeaderBytes"0how many bytes to skip at the beginning of the file

Basic Examples  (1)Basic Examples  (1)

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

In[1]:=
Click for copyable input
Out[1]=

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

In[2]:=
Click for copyable input
Out[2]=

Convert the binary data back to a list of integers:

In[3]:=
Click for copyable input
Out[3]=

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

In[4]:=
Click for copyable input
Out[4]=
