EEULAA Inclusion by adding an OpenType Table
From Fontlab Wiki
One suggestion about how to add the Electronic EULA Abstract (EEULAA) to fonts is to create a new OpenType table with standard fields. Emil Yakupov has created a (Windows) demo application which creates such a table and inserts it into a font and reads such tables from fonts. Here is the table description:
The table contains the principal positions of the EEULA abstract in simplified (machine readable) form. Each position of the EEULA abstract is represented by an identifier, bit value, numeric value and optional text (Unicode).
General structure of the EEULA abstract table (table tag "EULA"):
struct HEADER
struct DATA_FIELD[]
struct STRING_FIELD[]
(Variable) Storage for the actual string data.
Structure
HEADER {
DWORD dwVersion;
USHORT wNumFields;
USHORT wOffsetToStrings;
}
dwVersion – version number (current is 1.0)
wNumFields – number of DATA_FIELD records
wOffsetToStrings – offset to beginning of text data (Variable) from beginning of table EULA
Structure
DATA_FIELD {
WORD wFiled_id;
USHORT wBitValue;
SHORT wNumValue;
USHORT wNumOfStrings;
USHORT wStringStructOffset;
}
wField_id – section identifier, low byte – section id, high byte – subsection id.
wBitValue – see Table 2 for meanings
wNumValue – Numeric value (e.g. number of CPUs).
Negative value –1 means “unlimited”.
wNumOfStrings – number of text structures STRING_ID_REC
wStringOffest – offset to corresponding structure STRING_ID_REC.
struct STRING_ID_REC {
USHORT wLangId;
USHORT wStringLength;
USHORT wOffsetToString;
};
lang_id – language id
string_length – string length
wOffsetToString – offset to text string from beginning of text data in table (Variable). Absolute address can be calculated as HEADER.wOffsetToStrings + STRING_ID_REC.wOffsetToString
