Converts a character code from the current Code Page value to its UNICODE representation.
Declaration:
| |
 Copy Code |
AT_ERRCOUNT ACCUAPI IG_REC_util_codepage_to_unicode(
LPAT_BYTE pCodepageBuffer,
AT_INT codepageBufferLength,
AT_WCHAR * pUnicode,
LPAT_INT pActualLen
);
|
Arguments:
| pCodepageBuffer |
Pointer to character code to be converted. |
| codepageBufferLength |
The size of the buffer from which the character code is to be read. |
| pUnicode |
Pointer to a UNICODE buffer for the converted character code. |
| pActualLen |
Pointer to a variable to hold the actual number of bytes read for the character code. |
Return Value:
Returns the number of ImageGear errors that occurred during this function call.
Supported Raster Image Formats:
This function does not process image pixels.
Remarks:
- This function can be useful whenever a character or a character string from output should be passed to an API function requiring the character's or strings's UNICODE representation (e.g., IG_REC_output_rejection_symbol_set).
- The current Code Page may have been set or changed by a previous IG_REC_output_codepage_set function call.

AT_ERRCOUNT ErrCount = 0;

HIG_REC_IMAGE higRecImage = 0;
