Converts a UNICODE character code to its representation in the current code page.
Declaration:
 Copy Code |
|
|---|---|
AT_ERRCOUNT ACCUAPI IG_REC_util_unicode_to_codepage( AT_WCHAR Unicode, LPAT_BYTE pCodePageBuffer, AT_INT codepageBufferLength ); |
|
Arguments:
| Name | Type | Description |
| Unicode | AT_WCHAR | Character code to be converted. |
| pCodePageBuffer | LPAT_BYTE | Pointer of a variable to store the result of the conversion. |
| codepageBufferLength | AT_INT | Length of the output buffer. Must be large enough to hold the converted character. |
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.
Example:
| Copy Code |
|
|---|---|
AT_ERRCOUNT ErrCount = 0; HIGEAR higImage = 0; HIG_REC_IMAGE higRecImage = 0; LPAT_BYTE lpBuffer = 0; AT_INT iBufLen = 0; AT_WCHAR wcUnicode = L'�'; AT_INT iActualLen = 0; ErrCount += IG_load_file("Image.tif", &higImage); ErrCount += IG_REC_image_import(higImage, &higRecImage); ErrCount += IG_REC_image_recognize(higRecImage); ErrCount += IG_REC_output_codepage_set("Windows ANSI"); ErrCount += IG_REC_util_unicode_to_codepage_length_get(wcUnicode, &iActualLen); lpBuffer = (LPAT_BYTE) malloc(iActualLen); ErrCount += IG_REC_util_unicode_to_codepage(wcUnicode, lpBuffer, iActualLen); //... free(lpBuffer); ErrCount += IG_REC_image_delete(higRecImage); ErrCount += IG_image_delete(higImage); |

Remarks:
The current Code Page can be changed by a previous IG_REC_output_codepage_set function call. The length of the output character can be retrieved with the IG_REC_util_unicode_to_codepage_length_get function call.
