TrueType Fonts
In order to store information about TrueType fonts, the element TTFONT is stored as a member of the FTWL (Font World) element in the SYSTEM database. It has the following attributes:
•
TTFIND - numerical font ID
•
TTFACE - TrueType font face name (e.g. 'Arial')
•
TTFDES - TrueType font description to be shown to the user in the application's user interface
TTFIND
The whole font ID interval (1 to 63) has been divided into ranges reserved for AVEVA fonts, and for TrueType fonts:

AVEVA
This provides the ability to register up to 23 TrueType fonts per project. Unlike for AVEVA fonts, a single TrueType font includes all combinations of styles: standard, bold, italic, and bold italic. Whereas the 'italic' style corresponds to the 'Forward' AVEVA font style, there is no equivalent for 'Reverse' AVEVA font style in TrueType fonts.
TTFACE
The font face name is the name by which a font is recognised by the operating system. Even though the fonts like 'Arial', 'Times New Roman', or 'Courier New' should be available on all Microsoft Windows operating systems, they can have a different font face name on some localised versions of Windows.
TTFDES
The font description is the text to be shown to the user, whereas the face name is intended to be used only internally. It is initialised to be the same as the font face name, but can be modified by the administrator.
