Common Information on Fonts and Characters
This subsection describes some functions making common information
available. This includes Type 1 and AFM data. Thus, these
functions partially depend on the existence of AFM data. In order not
to have to specify this data every time, here are a few conventions:
FontID
is the valid ID of a declared font.
- All functions that require a character index as argument
use the currently active encoding vector to determine the
character's name
belonging to this index and use the character's name to search for the
information required.
- Some functions do not allow to use the return value for error
checking. For this reason every function described in this subsection will
set
T1_errno
appropriately if something goes wrong. See
for the description of the possible values of
T1_errno
.
- None of the functions described in this subsection will load a font
automatically.
