How to set load_system_dawg and load_freq_dawg to false ??
I need to disable the dictionary.. So I guess these are the two parameteres I need to set to false?
tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
if(api->Init(NULL, "dan+eng")){
// error
}
api->SetImage(image);
api->Recognize(0);
tesseract 3.05.01
In your tessdata directory create a configs directory
Create a file config (you will pass name of config file later in code)
Fill your config file with following text
load_system_dawg F
load_freq_dawg F
Modify your code
auto numOfConfigs = 1;
auto **configs = new char *[numOfConfigs];
configs[i] = (char *) "name of your config file";
tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
if(api->Init(NULL, "dan+eng", tesseract::OEM_DEFAULT, configs, numOfConfigs, nullptr, nullptr, false)){
// error
}
P.S. It is also possible to do with last couple of arguments of Init function, feel free to try them out yourself.
After reading the following link:
enter link description here
search for load_system_dawg in the document.
It says that a value of 1 will load the dictionaries, similarly for load_freq_dawg.
Using a value of 0 = false, we can disable frequency words and the dictionary as follows:
//pseudo code
api.setVariable("load_system_dawg","0");
api.setVariable("load_freq_dawg","0");

I'm trying to get clang::CompilerInstance to parse a source file which contains an include, but I can't figure out how to get it to actually find the included header. Here is my set up:
std::unique_ptr<clang::CompilerInstance> ci(new clang::CompilerInstance());
ci->createDiagnostics();
LLVMInitializeARMTarget();
LLVMInitializeARMTargetMC();
LLVMInitializeARMAsmPrinter();
LLVMInitializeARMAsmParser();
std::shared_ptr<clang::TargetOptions> options(new clang::TargetOptions);
options->Triple = "arm-v7m-unknown-none-eabi";
options->CPU = "cortex-m3";
clang::TargetInfo *targetInfo = clang::TargetInfo::CreateTargetInfo(ci->getDiagnostics(), options);
ci->setTarget(targetInfo);
ci->createFileManager();
ci->createSourceManager(ci->getFileManager());
NSURL *sysrootURL = [[[NSBundle mainBundle] resourceURL] URLByAppendingPathComponent:#"Compiler/basalt"];
NSURL *includeURL = [sysrootURL URLByAppendingPathComponent:#"include"];
ci->createPreprocessor(clang::TranslationUnitKind::TU_Complete);
ci->getPreprocessorOpts().UsePredefines = false;
// Header searcher
llvm::IntrusiveRefCntPtr<clang::HeaderSearchOptions> hso(new clang::HeaderSearchOptions());
hso->UseBuiltinIncludes = false;
hso->UseStandardSystemIncludes = false;
hso->UseStandardCXXIncludes = false;
hso->Sysroot = [[includeURL path] UTF8String];
clang::HeaderSearch headerSearch(hso, ci->getSourceManager(), ci->getDiagnostics(), ci->getLangOpts(), targetInfo);
headerSearch.AddSearchPath(clang::DirectoryLookup(ci->getFileManager().getDirectory([[includeURL path] UTF8String]), clang::SrcMgr::C_System, false), true);
clang::InitializePreprocessor(ci->getPreprocessor(), ci->getPreprocessorOpts(), ci->getFrontendOpts());
// Main file
const clang::FileEntry *file = ci->getFileManager().getFile([[[_url URLByAppendingPathComponent:#"src/main.c"] path] UTF8String]);
ci->getSourceManager().setMainFileID(ci->getSourceManager().createFileID(file, clang::SourceLocation(), clang::SrcMgr::C_User));
ci->getPreprocessor().EnterMainSourceFile();
ci->getDiagnosticClient().BeginSourceFile(ci->getLangOpts(), &ci->getPreprocessor());
clang::Token tok;
do {
ci->getPreprocessor().Lex(tok);
if(ci->getDiagnostics().hasErrorOccurred())
break;
ci->getPreprocessor().DumpToken(tok);
std::cerr << std::endl;
} while(tok.isNot(clang::tok::eof));
ci->getDiagnosticClient().EndSourceFile();
The paths are definitely 100% correct and checked them over and over again. It all works up until the point the source code I throw at it contains something like #include <foobar.h>, in which case it will fail with error 'foobar.h' file not found, even though foobar.h is definitely there. I feel like I'm missing something really obvious here. Any pointers into the right direction?
Firstly, drop using CompilerInstance- the ownership semantics are so bad it's practically unusable (unless they fixed that in 3.6 with unique_ptr). It's easier to simply make the components yourself.
Secondly, yes, you have to do it yourself. Here's a verbatim excerpt from my own project that uses Clang:
clang::HeaderSearch hs(/*params*/);
// WHY AM I DOING THIS MYSELF CLANG
// CAN'T YOU READ YOUR OWN CONSTRUCTOR PARAMETERS AND OPTIONS STRUCTS?
std::vector<clang::DirectoryLookup> lookups;
for (auto entry : opts.HeaderSearchOptions->UserEntries) {
auto lookup = clang::DirectoryLookup(FileManager.getDirectory(entry.Path), clang::SrcMgr::CharacteristicKind::C_System, false);
if (!lookup.getDir())
throw SpecificError<ClangCouldNotInterpretPath>(a, where, "Clang could not interpret path " + entry.Path);
lookups.push_back(lookup);
}
hs.SetSearchPaths(lookups, 0, 0, true);
I want to use the DCMTK 3.6.1 library in an existing project that can create DICOM image. I want to use this library because I want to make the compression of the DICOM images. In a new solution (Visual Studio 2013/C++) Following the example in the DCMTK official documentation, I have this code, that works properly.
using namespace std;
int main()
{
DJEncoderRegistration::registerCodecs();
DcmFileFormat fileformat;
/**** MONO FILE ******/
if (fileformat.loadFile("Files/test.dcm").good())
{
DcmDataset *dataset = fileformat.getDataset();
DcmItem *metaInfo = fileformat.getMetaInfo();
DJ_RPLossless params; // codec parameters, we use the defaults
// this causes the lossless JPEG version of the dataset
//to be created EXS_JPEGProcess14SV1
dataset->chooseRepresentation(EXS_JPEGProcess14SV1, ¶ms);
// check if everything went well
if (dataset->canWriteXfer(EXS_JPEGProcess14SV1))
{
// force the meta-header UIDs to be re-generated when storing the file
// since the UIDs in the data set may have changed
delete metaInfo->remove(DCM_MediaStorageSOPClassUID);
delete metaInfo->remove(DCM_MediaStorageSOPInstanceUID);
metaInfo->putAndInsertString(DCM_ImplementationVersionName, "New Implementation Version Name");
//delete metaInfo->remove(DCM_ImplementationVersionName);
//dataset->remove(DCM_ImplementationVersionName);
// store in lossless JPEG format
fileformat.saveFile("Files/carrellata_esami_compresso.dcm", EXS_JPEGProcess14SV1);
}
}
DJEncoderRegistration::cleanup();
return 0;
}
Now I want to use the same code in an existing C++ application where
if (infoDicom.arrayImgDicom.GetSize() != 0) //Things of existing previous code
{
//I have added here the registration
DJEncoderRegistration::registerCodecs(); // register JPEG codecs
DcmFileFormat fileformat;
DcmDataset *dataset = fileformat.getDataset();
DJ_RPLossless params;
dataset->putAndInsertUint16(DCM_Rows, infoDicom.rows);
dataset->putAndInsertUint16(DCM_Columns, infoDicom.columns,);
dataset->putAndInsertUint16(DCM_BitsStored, infoDicom.m_bitstor);
dataset->putAndInsertUint16(DCM_HighBit, infoDicom.highbit);
dataset->putAndInsertUint16(DCM_PixelRepresentation, infoDicom.pixelrapresentation);
dataset->putAndInsertUint16(DCM_RescaleIntercept, infoDicom.rescaleintercept);
dataset->putAndInsertString(DCM_PhotometricInterpretation,"MONOCHROME2");
dataset->putAndInsertString(DCM_PixelSpacing, "0.086\\0.086");
dataset->putAndInsertString(DCM_ImagerPixelSpacing, "0.096\\0.096");
BYTE* pData = new BYTE[sizeBuffer];
LPBYTE pSorg;
for (int nf=0; nf<iNumberFrames; nf++)
{
//this contains all the PixelData and I put it into the dataset
pSorg = (BYTE*)infoDicom.arrayImgDicom.GetAt(nf);
dataset->putAndInsertUint8Array(DCM_PixelData, pSorg, sizeBuffer);
dataset->chooseRepresentation(EXS_JPEGProcess14SV1, ¶ms);
//and I put it in my data set
//but this IF return false so che canWriteXfer fails...
if (dataset->canWriteXfer(EXS_JPEGProcess14SV1))
{
dataset->remove(DCM_MediaStorageSOPClassUID);
dataset->remove(DCM_MediaStorageSOPInstanceUID);
}
//the saveFile fails too, and the error is "Pixel
//rappresentation non found" but I have set the Pixel rep with
//dataset->putAndInsertUint16(DCM_PixelRepresentation, infoDicom.pixelrapresentation);
OFCondition status = fileformat.saveFile("test1.dcm", EXS_JPEGProcess14SV1);
DJEncoderRegistration::cleanup();
if (status.bad())
{
int error = 0; //only for test
}
thefile.Write(pSorg, sizeBuffer); //previous code
}
Actually I made test with image that have on one frame, so the for cycle is done only one time. I don't understand why if I choose dataset->chooseRepresentation(EXS_LittleEndianImplicit, ¶ms); or dataset->chooseRepresentation(EXS_LittleEndianEXplicit, ¶ms); works perfectly but not when I choose dataset->chooseRepresentation(EXS_JPEGProcess14SV1, ¶ms);
If I use the same image in the first application, I can compress the image without problems...
EDIT: I think the main problem to solve is the status = dataset->chooseRepresentation(EXS_JPEGProcess14SV1, &rp_lossless) that return "Tag not found". How can I know wich tag is missed?
EDIT2: As suggest in the DCMTK forum I have added the tag about the Bits Allocated and now works for few images, but non for all. For some images I have again "Tag not found": how can I know wich one of tags is missing? As a rule it's better insert all the tags?
I solve the problem adding the tags DCM_BitsAllocated and DCM_PlanarConfiguration. This are the tags that are missed. I hope that is useful for someone.
At least you should call the function chooseRepresentation, after you have applied the data.
**dataset->putAndInsertUint8Array(DCM_PixelData, pSorg, sizeBuffer);**
dataset->chooseRepresentation(EXS_JPEGProcess14SV1, ¶ms);
I have my xml as char buffer (that's fetched from server, I don't want to save it -> takes extra time and is completely obsolete):
char myword[] = "...xml..."
xmlSchemaParserCtxtPtr ctxt = xmlSchemaNewParserCtxt(xsdFilePath);
xmlDocPtr doc = ?;
Now I need to get doc. I'm trying to use following function:
doc = xmlReadMemory(myword, sizeof(myword), ?URL?, NULL, 0)
But the problem is with URL, what should I put in there..? Am I using this function right? Maybe there is another way to get xmlDocPtr?
BTW: I need xmlDocPtr to perform:
ret = xmlSchemaValidateDoc(ctxt, doc);
Simply pass a NULL pointer:
doc = xmlReadMemory(myword, sizeof(myword), NULL, NULL, 0);
I have a need to create an action that will:
1. copy a selected part (selected by hand) of an image in an already opened file
2. paste selection into new file
3. save new file as jpg file, but not with default file name of "untitled.jpg" - instead use a unique name or use a auto-increment suffix
Because the action will be run multiple times on different selections from the same image, saving each selection with a unique name or auto-incremented suffix would save the step of manually supplying the filename each time a different selection is saved.
I can create an action that gets to the save-as step, but don't know if it is possible to modify the default save as name as described above. Is it possible?
No. Tried it before with no success. You have to save manually.
Don't think this is possible with an action but you can write a script do to it.
I have created a script for similar work. It uses a technique to generate unique filenames and save the file.
/************************************************************************

I know this is old, but still. You can use the following script.
How to use a script:
Copy the following script in notepad, and save it in directory similar to "C:\Program Files (x86)\Adobe\Adobe Photoshop CS2\Presets\Scripts" with the extension JSX.
To run the scrip in photoshop, go to File > Scripts > "Your Script".
#target photoshop
main();
function main(){
if(!documents.length) return;
var Name = app.activeDocument.name.replace(/.[^.]+$/, '');
Name = Name.replace(/\d+$/,'');
try{
var savePath = activeDocument.path;
}catch(e){
alert("You must save this document first!");
}
var fileList= savePath.getFiles(Name +"*.jpg").sort().reverse();
var Suffix = 0;
if(fileList.length){
Suffix = Number(fileList[0].name.replace(/\.[^\.]+$/, '').match(/\d+$/));
}
Suffix= zeroPad(Suffix + 1, 4);
var saveFile = File(savePath + "/" + Name + "_" + Suffix + ".jpg");
SaveJPG(saveFile);
}
function SaveJPG(saveFile){
//Create a jpg document with standard options
jpgSaveOptions = new JPEGSaveOptions();
jpgSaveOptions.embedColorProfile = true;
jpgSaveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
jpgSaveOptions.matte = MatteType.NONE;
jpgSaveOptions.quality = 12;
//Save jpg with incremental file names (1.jpg, 2.jpg), make sure the path exists
activeDocument.saveAs(saveFile, jpgSaveOptions, true, Extension.LOWERCASE);
};

I'm generating a reporting services report from an ASP.NET (MVC) based application but am having problems setting the parameters for the report.
I believe the issue has only occurred since we upgraded SQL Server from 2005 to 2008 R2 (and Reporting Services along with it).
The original error encountered was from calling rsExec.Render:
Procedure or function 'pCommunication_ReturnRegistrationLetterDetails'
expects parameter '#guid', which was not supplied.
Debugging the code I noticed that rsExec.SetExecutionParameters is returning the following response:
Cannot call 'NameOfApp.SQLRSExec.ReportExecutionService.SetExecutionParameters(NameOfApp.SQLRSExec.ParameterValue[],
string)' because it is a web method.
Here is the function in it's entirety:
public static bool ProduceReportToFile(string reportname, string filename, string[,] reportparams,
string fileformat)
{
bool successful = false;
SQLRS.ReportingService2005 rs = new SQLRS.ReportingService2005();
SQLRSExec.ReportExecutionService rsExec = new NameOfApp.SQLRSExec.ReportExecutionService();
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
rsExec.Credentials = System.Net.CredentialCache.DefaultCredentials;
// Prepare Render arguments
string historyID = null;
string deviceInfo = null;
// Prepare format - available options are "PDF","Word","CSV","TIFF","XML","EXCEL"
string format = fileformat;
Byte[] results;
string encoding = String.Empty;
string mimeType = String.Empty;
string extension = String.Empty;
SQLRSExec.Warning[] warnings = null;
string[] streamIDs = null;
// Define variables needed for GetParameters() method
// Get the report name
string _reportName = reportname;
string _historyID = null;
bool _forRendering = false;
SQLRS.ParameterValue[] _values = null;
SQLRS.DataSourceCredentials[] _credentials = null;
SQLRS.ReportParameter[] _parameters = null;
// Get if any parameters needed.
_parameters = rs.GetReportParameters(_reportName, _historyID,
_forRendering, _values, _credentials);
// Load the selected report.
SQLRSExec.ExecutionInfo ei =
rsExec.LoadReport(_reportName, historyID);
// Prepare report parameter.
// Set the parameters for the report needed.
SQLRSExec.ParameterValue[] parameters =
new SQLRSExec.ParameterValue[1];
// Place to include the parameter.
if (_parameters.Length > 0)
{
for (int i = 0; i < _parameters.Length; i++)
{
parameters[i] = new SQLRSExec.ParameterValue();
parameters[i].Label = reportparams[i,0];
parameters[i].Name = reportparams[i, 0];
parameters[i].Value = reportparams[i, 1];
}
}
rsExec.SetExecutionParameters(parameters, "en-us");
results = rsExec.Render(format, deviceInfo,
out extension, out encoding,
out mimeType, out warnings, out streamIDs);
// Create a file stream and write the report to it
using (FileStream stream = System.IO.File.OpenWrite(filename))
{
stream.Write(results, 0, results.Length);
}
successful = true;
return successful;
}
Any ideas why I'm now unable to set parameters? The report generation works without issue if parameters aren't required.
Looks like it may have been an issue with how reporting services passes parameters through to the stored procedure providing the data. A string guid was being passed through to the report and the stored procedure expected a varchar guid. I suspect reporting services may have been noticing the string followed the guid format pattern and so passed it through as a uniqueidentifier to the stored procedure.
I changed the data source for the report from "stored procedure" to "text" and set the SQL as "EXEC pMyStoredOProcName #guid".
Please note the guid being passed in as a string to the stored procedure is probably not best practice... I was simply debugging an issue with another developers code.
Parameter _reportName cannot be null or empty. The [CLASSNAME].[METHODNAME]() reflection API could not create and return the SrsReportNameAttribute object
In this specific case it looks like an earlier full compile did not finish.
If you encounter this problem I would suggest that you first compile the class mentioned in the error message and see if this solves the problem.
go to AOT (get Ctrl+D)
in classes find CLASSNAME
3.compile it (F7)
