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.
