Working with Recognition Results
To add code to an existing project in order to work with recognition results:
1. |
Start with the program you created in Recognize Pages. |
||
2. |
Define the following global IDs in Ezfunc.h in the DocumentTutor directory: |
|
#define IDM_GET_OUTPUTFORMAT 207
#define IDM_SAVE_RESULTS 208
3. |
Edit EZFUNC.RC file in the DocumentTutor directory and add the following lines: |
MAIN_MENU MENU
BEGIN
...
...
MENUITEM "Get Output Formats" IDM_GET_OUTPUTFORMAT
MENUITEM "Save Results" IDM_SAVE_RESULTS
END
4. |
In the MainWndProc procedure, add the following code to the switch statement for WM_COMMAND: |
case IDM_GET_OUTPUTFORMAT:
{
nRet = L_DocEnumOutputFileFormats(hDoc, EnumOutputFileFormatsCB, NULL);
if (nRet != SUCCESS)
{
wsprintf (achBuff, TEXT("Error %d enumerating available file formats"), nRet);
MessageBox (NULL, achBuff, TEXT("Error"), MB_OK);
}
}
break;
case IDM_SAVE_RESULTS:
{
RESULTOPTIONS ResOpts;
memset(&ResOpts, 0, sizeof(RESULTOPTIONS));
nRet = L_DocGetRecognitionResultOptions(hDoc, &ResOpts, sizeof(RESULTOPTIONS));
if (nRet == SUCCESS)
{
ResOpts.Format = DOC_WORD_97_2000_XP;
ResOpts.FormatLevel = FORMAT_LEVEL_FULL;
ResOpts.DocOptions.PaperSize = SEL_PREDEFINED;
ResOpts.DocOptions.PaperType = PAPER_TYPE_A4;
L_DocSetRecognitionResultOptions(hDoc, &ResOpts);
nRet = L_DocSaveResultsToFile (hDoc, TEXT("c:\\test.doc"));
if (nRet != SUCCESS)
{
wsprintf (achBuff, TEXT("Error %d in saving recognition results to a file"), nRet);
MessageBox (NULL, achBuff, TEXT("Error"), MB_OK);
}
}
}
break;
5. |
Add the following function in EZFUNC.CPP in DocumentTutor directory. |
L_INT EXT_CALLBACK EnumOutputFileFormatsCB(FORMAT_TYPE
Format, L_VOID * pUserData)
{
UNREFERENCED_PARAMETER(pUserData);
TEXTFORMATINFO FormatInfo;
L_INT nRet;
L_TCHAR szBuffer[1024];
memset(&FormatInfo, 0, sizeof(TEXTFORMATINFO));
nRet = L_DocGetTextFormatInfo(hDoc, Format, &FormatInfo, sizeof(TEXTFORMATINFO));
if (nRet == SUCCESS)
{
wsprintf(szBuffer, TEXT("Format Name = %s\nFormat DLL Name = %s\nFormat Ext Name = %s\n"),
FormatInfo.pszName,
FormatInfo.pszDLLName,
FormatInfo.pszExtName);
MessageBox(NULL, szBuffer, TEXT("Format Info"), MB_OK);
switch (FormatInfo.Type)
{
case OUT_TYPE_PLAIN:
wsprintf(szBuffer, TEXT("Format Type = Plain"));
break;
case OUT_TYPE_WORD_PROCESSOR:
wsprintf(szBuffer, TEXT("Format Type = Word Processor"));
break;
case OUT_TYPE_TRUE_WORD_PROCESSOR:
wsprintf(szBuffer, TEXT("Format Type = True Word Processor"));
break;
case OUT_TYPE_TABLE:
wsprintf(szBuffer, TEXT("Format Type = Table"));
break;
case OUT_TYPE_UNKNOWN:
wsprintf(szBuffer, TEXT("Format Type = Unknown"));
break;
}
MessageBox(NULL, szBuffer, TEXT("Format Type"), MB_OK);
}
return SUCCESS;
}
6. |
Also, add the following statement before the MainWndProc function |
L_INT EXT_CALLBACK EnumOutputFileFormatsCB(FORMAT_TYPE Format, L_VOID * pUserData);
7. |
Build SimpleLoad.exe. |
8. |
Run SimpleLoad.exe. |
