* These types are used to support a `BDF ' table that isn't part of the | |
* official TrueType specification. It is mainly used in SFNT-based | |
* bitmap fonts that were generated from a set of BDF fonts. | |
* | |
* The format of the table is as follows. | |
* | |
* USHORT version `BDF ' table version number, should be 0x0001. | |
* USHORT strikeCount Number of strikes (bitmap sizes) in this table. | |
* ULONG stringTable Offset (from start of BDF table) to string | |
* table. | |
* | |
* This is followed by an array of `strikeCount' descriptors, having the | |
* following format. | |
* | |
* USHORT ppem Vertical pixels per EM for this strike. | |
* USHORT numItems Number of items for this strike (properties and | |
* atoms). Maximum is 255. | |
* | |
* This array in turn is followed by `strikeCount' value sets. Each | |
* `value set' is an array of `numItems' items with the following format. | |
* | |
* ULONG item_name Offset in string table to item name. | |
* USHORT item_type The item type. Possible values are | |
* 0 => string (e.g., COMMENT) | |
* 1 => atom (e.g., FONT or even SIZE) | |
* 2 => int32 | |
* 3 => uint32 | |
* 0x10 => A flag to indicate a properties. This | |
* is ORed with the above values. | |
* ULONG item_value For strings => Offset into string table without | |
* the corresponding double quotes. | |
* For atoms => Offset into string table. | |
* For integers => Direct value. | |
* | |
* All strings in the string table consist of bytes and are | |
* zero-terminated. | |
