I'm trying to develop a X-platform tool with Tesseract, but I'm having
problems.
My Tesseract's API works fine, for example, the next code compiled in C++
does work:
tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
putenv("TESSDATA_PREFIX=/Users/rafaelruizmunoz/Desktop");
api->Init(NULL, "eng");
api->SetPageSegMode(tesseract::PSM_SINGLE_LINE);
api->SetVariable("tessedit_char_whitelist", "0123456789/");Pix *image =
pixRead("/Users/rafaelruizmunoz/Desktop/6a00d8341bfb1653ef0192acb84130970d.jpg");
api->SetImage(image);
so, no problem.
Now, I try to implement it for iPhone. From the iPhone I'm passing the path
where I'm going to store images to then load them with Tesseract (I can't
pass them from Mat to PIX):
string nameFile = "/tempTime" + to_string(i) + to_string(j) + ".jpg";
string cPathString = folder + nameFile;const char* cPath = cPathString.c_str();
filenameVector.push_back(cPath);
imwrite(cPath, date);
The image is saved sucessfully (imwrite = 1).
But then when I load it as:
tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();;
api->Init(resourcePath.c_str(), "eng");
api->SetPageSegMode(tesseract::PSM_SINGLE_LINE);
api->SetVariable("tessedit_char_whitelist", "0123456789/");Pix *image =
pixRead(filenameVector.at(i).c_str());
the image is NULL, and the errors are:
Error in pixReadStreamJpeg: function not present
Error in pixReadStream: jpeg: no pix returned
Error in pixRead: pix not read
Error in pixGetDimensions: pix not defined
Error in pixGetColormap: pix not defined
Error in pixClone: pixs not defined
Error in pixGetDepth: pix not defined
Error in pixGetWpl: pix not defined
Error in pixGetYRes: pix not defined
Please call SetImage before attempting recognition.
I'm pretty sure that the file still exists, because if I do:
Mat matInserted = imread(filenameVector.at(i).c_str());
the matInserted is my image (seen it from debug).
What is going wrong? Thanks.
