TRANSDATA structure (prntfont.h)

The TRANSDATA structure is one of the structures used to define the contents of glyph translation table files (.gtt files).

Syntax

typedef struct _TRANSDATA {
  BYTE  ubCodePageID;
  BYTE  ubType;
  union {
    SHORT sCode;
    BYTE  ubCode;
    BYTE  ubPairs[2];
  } uCode;
} TRANSDATA, *PTRANSDATA;

Members

ubCodePageID

Specifies the zero-based index of a particular structure in the array of UNI_CODEPAGEINFO structures. The first structure in this array has an index of 0, the second structure has an index of 1, and so on.

The loCodePageOffset member of the UNI_GLYPHSETDATA structure contains the offset from the beginning of the UNI_GLYPHSETDATA structure to the beginning of the array of UNI_CODEPAGEINFO structures.

ubType

Is a set of one or more bit flags, as follows:

One of the following three format flags can be set:

Flag	Format
MTYPE_COMPOSE	The sCode member of the uCode union contains an offset to a string. The string contains a command to be sent to the printer.
MTYPE_DIRECT	The ubCode member of the uCode union contains a one-byte character code to be sent to the printer.
MTYPE_PAIRED	The ubPairs member of the uCode union contains a two-byte character code to be sent to the printer.

One of the action following flags can be set. All are optional. Not valid if the lPredefinedID member of the UNI_GLYPHSETDATA structure is set to CC_NOPRECNV.

Flag	Action
MTYPE_ADD	The specified mapping is added to the map table contained in the .gtt file specified by the lPredefinedID member of the UNI_GLYPHSETDATA structure.
MTYPE_DISABLE	The specified mapping, contained in the .gtt file specified by the lPredefinedID member of the UNI_GLYPHSETDATA structure, is disabled.
MTYPE_REPLACE	The specified mapping replaces mapping in the map table contained in the .gtt file specified by the lPredefinedID member of the UNI_GLYPHSETDATA structure.

One of the following East Asian flags can be set:

Flag	East Asian Format
MTYPE_SINGLE	Character data is single-byte.
MTYPE_DOUBLE	Character data is double-byte.

uCode

uCode.sCode

Specifies the offset to a command string. The offset is relative to the beginning of the MAPTABLE structure containing the TRANSDATA array. The first word of the command string must be the command size. Valid if the MTYPE_COMPOSE flag is set in uType.

uCode.ubCode

Specifies a one-byte character code. Valid if the MTYPE_DIRECT flag is set in uType.

uCode.ubPairs[2]

Specifies a two-byte character code. Valid if the MTYPE_PAIRED flag is set in uType.

Remarks

A .gtt file's TRANSDATA structure array, which contains glyph mapping information, is contained in the file's MAPTABLE structure.
