Saving Cross Section Data

Menu for saving cross sections

By right-clicking on the cross cross section region, the cross section data can be saved to a file in the following formats:

• XML
• CSV
• Binary (See below)
• JSON

By default, the export will save in the directory of the original collection.

Save options.

Binary Format

The Cross Section binary format is as follows. All numeric values are little-endian format.

• A header consisting of:
  • 1-byte version #
  • 4-byte String ID in ASCII ("OKOS")

• Horizontal Cross-section data:
  • 1-byte id for the Horizontal cross section data (ASCII "H")
  • 4-byte (int32) # of horizontal cross sections. As of this writing it should only be 1.
  • 4-byte (int32) Minimum cross section raw value (e.g., 0)
  • 4-byte (int32) Maximum cross section raw value (e.g. 128 for 8-bit data)
  • 8-byte (double) Minimum cross section value in units (e.g. 0 )
  • 8-byte (double) Range of cross section values in units (e.g. 100)
  • 4-byte (int32) length of the units string (below)
  • n-byte ASCII representation of the cross section value units (e.g. "%FSH")
  • 8-byte (double) of the resolution between samples
  • 4-byte (int32) length of the sample units string (below)
  • n-byte ASCII representation of the sample units string (e.g. "mm")
  • 4-byte (int32) number of cross section samples
  • n-byte (int32) cross section samples. each sample is a 4-byte integer.

• Vertical cross section data:
  • 1-byte id for the Vertical cross section data (ASCII "V")
  • All other entries are identical to the Horizontal cross-section data description above.
