STYLE Table

The STYLE table stores all text styles and shape-file definitions. The “STANDARD” entry must always exist.

Shape-files are also defined by a STYLE table entry, the bit 0 of the flags-tag is set to 1 and the name-tag is an empty string, the only important data is the font-tag with group code 3 which stores the associated SHX font file.
