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.

These values are used by the comment headers and comment blocks to designate the type of comment stored.
