Member Data Documentation

theNumberOfBytes

long ossimRpfMaskSubheader::theNumberOfBytes

private

This is just a working variable and is not part of the Rpf fields. this is the number of bytes of the output pixel code length. It divides by 8 and then does the ceiling of the theTransparentOutputPixelCodeLength.
