TagData
The formatted tag value. Please follow the formats below for individual tag types:
  • BYTE tags will have this mask: "#,#,...,#".[#] : A component as unsigned 8-bit integer with a value between 0 and 255.[,] : A component delimiter.
  • SHORT tags will have this mask: "#,#,...,#".[#] : A component as unsigned 16-bit integer with a value between 0 and 65535.[,] : A component delimiter.
  • Integer tags will have this mask: "#,#,...,#".[#] : A component as unsigned 32-bit integer with a value between 0 and 4294967295.[,] : A component delimiter.
  • SInteger tags will have this mask: "#,#,...,#".[#] : A component as signed 32-bit integer with a value between -2147483648 and 2147483647.[,] : A component delimiter.
  • RATIONAL tags will have this mask: "#/#,#/#,...,#/#".[#/#] : A component will consist of two unsigned 32-bit integers denoting the enumerator and denominator. Each integer will have a value between 0 and 4294967295.[,] : A component delimiter.
  • SRATIONAL tags will have this mask: "#/#,#/#,...,#/#".[#/#] : A component will consist of two signed 32-bit integers denoting the' enumerator and denominator. Each integer will have a value between -2147483648 and 2147483647.[,] : A component delimiter.
