TRANSDATA structure

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:

Flag Definition
Format Flags One of the following three flags can be set.
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.
Action Flags One of the following flags can be set. All are optional. Not valid if the lPredefinedID member of the UNI_GLYPHSETDATA structure is set to CC_NOPRECNV.
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.
East Asian Flags One of the following flags can be set.
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

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.
