An array of alignment zones defines hints about glyphs defined in a DefineFont3.

The f_zone_count specifies how many zones are defined in a zone array. In version 8 of SWF, the count must be set to 2.

The f_zone_data is an array of zones, each defining a position and a size.

The f_zone_x and f_zone_y defines whether the horizontal and vertical positions and sizes are defined. At least one of these flag shall be set to 1.1

  • 1. Since in version 8 you must have 2 in f_zone_count, you most certainly need to set both of these flags to 1 in that version. In effect, all you can currently do is define one rectangle (zone).
