IZIUM graphic format - short description:

 IZIUM file format iz almost raw format developed for image storing purposes.
 The structure of IZIUM files is very simple:

Length of IZIUM header is always 18 bytes:
  • 4-byte integer value (reserved nonsignificant constant, usually is equal to zero)
  • 4-byte integer = number of image rows (Y)
  • 4-byte integer = number of image columns (X)
  • 2-byte integer = bytes per pixel (usually 1, 2 or 4)
  • 2-byte integer = smallest image value - may be different from real smallest image DN - it's not significant
  • 2-byte integer = greatest image value - may be different from real greatest image DN - it's not significant

    • --------------------------------
        total = 18 bytes

    Raw data stored as integer values in order of rows ( from 0 to Y-1 ).
    Within the row pixels stored in order of pixels ( from pixel = 0 to X-1 ).

    Total length of IZIUM files = 18 bytes(header) + bytes per pixel * number of image rows*number of image columns

    ATTENTION: bytes order in IZIUM files is compatible with PC or DEC computers - "least-significant-byte-first"
