I tested your sample image and confirmed the error. It looks like a bug in 
the routine that determines the image's bit depth. A new version will be 
released once a fix is worked out and committed.

Thank you for reporting.

[tesseract-ocr] Tess4J: Invalid memory access

2018-09-02 Thread Subramaniyan Suresh



I am using Tess4J in my project to extract text from an image (Using 
Eclipse IDE). I am getting the following error when I try run the OCR. Any 
suggestion?  

*Error: Exception in thread "main" java.lang.Error: Invalid memory access*


*Note: I have attached the image file which I've used *

*My Code*:


package tesseractTraining;


import java.io.File;

import net.sourceforge.tess4j.*;


public class TesseractMainRunner {

public static void main(String[] args) {

File imageFile = new File("E:\\Tesseract\\Test Images\\sample.png");

Tesseract instance = new Tesseract();

try {

instance.setDatapath("C:\\Program Files (x86)\\Tesseract-OCR\\tessdata");

instance.setLanguage("eng");

String result = instance.doOCR(imageFile);

System.out.println(result);

} catch (TesseractException e) {

System.err.println(e.getMessage());

}

imageFile.exists();

}


}

Re: [tesseract-ocr] What i need to do fine tuning for only numbers and specific font?

2018-09-02 Thread Yasin Nazlıcan

Hello Soumik,

Thank you for replying back, i find out that we can train tesseract in macOS 
. But i 
couldn't make it work,  when I say "make training" it gives me "Need to 
reconfigure project, so there are no errors" error. Also, I couldn't create 
ScrollView.jar. Do you know how can i find errors?
