See https://github.com/tesseract-ocr/tesseract/wiki/Compiling for windows
compiling instructions.

If you have cloned the repo once by git clone
https://github.com/tesseract-ocr/tesseract tesseract
you can update it using

*git pull origin*

Please rebuild leptonica with the latest source from github (
https://github.com/DanBloomberg/leptonica)
and then rebuild tesseract with the latest source from github (
https://github.com/tesseract-ocr/tesseract) and try.

[tesseract-ocr] How should Vs2015 solve this problem ?

2016-12-28 Thread 송민규

How should Vs2015 solve this problem ?
 Too many Error...

It looks like the pixRead function found the file "a.png" in C: \ datas, 
why does pixRead return a NULL value?

OS : Windows 10 pro
IDE tool : visual studio 2015 update 3
Teseract - ocr version link : https ://github.com/tesseract-ocr/tesseract 
(Tesseract Open Source OCR Engine(main repository))
leptonica version : 1.74.0

#include 
#include 
#include 

int main()

{
char * outText = nullptr;
Pix *image = nullptr;

tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
// Initialize tesseract-ocr with English, without specifying tessdata path
if (api->Init(NULL, "eng")) {
fprintf(stderr, "Could not initialize tesseract.\n");
exit(1);
}



image = pixRead("C:\\datas\\a.tif");
api->SetImage(image);
// Get OCR result
outText = api->GetUTF8Text();
printf("\n OCR output: %s \n", outText);

// Destroy used object and release memory
api->End();
delete[] outText;
pixDestroy();

return 0;

}

Output:
//
Error in pixReadStreamPng : function not present
Error in pixReadStream : no fix returned
Error in pixRead : pix not Read
Error in pixGetDimensions : pix not defined
Error in pixGetColormap : pix not defined
Error in pixGetCopy : Pixs not defined
Error in pixGetDepth : pix not defined
Error in pixGetWpl : pix not defined
Error in pixGetYRes : pix not defined
Error in pixGetClone : Pixs not defined

Please call SetImage before attempting recognition.
