FlashPix Enumerated Types

Enumerated types are used in FlashPix files to designate which Comment type is being stored. One of the values listed in FPXTYPE_DATA must be used when designating the Comment type in a Comment or in a sub-comment. (See FlashPix Comments.) The rest of the enumerated types are used for Comments or sub-comments which require that the data stored there belong to a particular group type. The enumerated types listed below provide a reference to those Comments using that enumerated type. In addition, an explanation, when needed, is given for each value of an enumerated type.
