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:
  1. FontID is the valid ID of a declared font.
  2. 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.
  3. 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.
  4. None of the functions described in this subsection will load a font automatically.
