I have gradually followed this document example, using netbeans. http://tess4j.sourceforge.net/tutorial/
My System configuration is as follow: Windows 7 64bit. JDK 1.8 Microsoft visual c++ 2015 86x already existed so i installed 2017 64bit also. I have also find and downloaded all the required jar files as you can see. commons-io-2.5.jar jai-imageio-core-1.3.1.jar jna-4.1.0.jar jul-to-slf4j-1.8.0-beta2.jar lept4j-1.10.0.jar logback-classic-1.1.3.jar logback-core-1.1.3.jar slf4j.jar tess4j-4.0.2.jar

I also added the testdata folder but i got this error

run: Exception in thread "main" java.lang.UnsatisfiedLinkError: The specified module could not be found.

i installed tesseraect from brew.

brew reinstall tesseract --all-languages --with-training-tools

tessdata path is /usr/local/share/ and it has chi_sim.traineddata

but when i use tess4j to load chi_sim, here is code

I'm facing null pointer exception at doOCR("filepath") method of tess4j while running tests on MAC OS 10.13.5 but same tests are running without exception on Windows 10 OS ().

kindly let me know if there is any dependency to be installed for MAC OS.

Details

Tess4j ver 4.2.3 Java 8

Hi, I am using tess4j in my demo project and get errors as showed below....

Some informations if you need OS: Ubuntu 16.04 IDE: Intellij IDEA Tesseract:

The tesseract works fine in command line but not in java...

other informations

1. As mentioned in this link.. This problem also happens in python environment. Just want more people can help, so i submit issue also in here...
2. As mentioned in this link. These codes are added in 4.0.0-beta.3 and i am using 4.0.0-beta.1.

So,,,,how can i solve this problem??

We are having trouble making the code below work. Could it be the PdfUtilities? We really appreciate any help. The stack trace is at the bottom. Let us know if you need more information.

Solutions attempted:

(1) Tried including Ghostscript ghost4j 1.0.0 in the maven dependencies. The library was in the classpath correctly. Results: Stack trace shown below - Note: I was able to instantiate Ghostscript objects using the factory without any issues inside void main. (2) Followed the solution described here https://github.com/nguyenq/tess4j/issues/4 Results: same as (1)

Stack Trace:

The issue happens on the line * File pngImageFiles[] = PdfUtilities.convertPdf2Png(pdfDoc);*

Hello, I have seen on the Internet that it is possible to use tesseract with OpenCL. Could tess4j support it ? It would be a tremendous feature. Vulkan ? But it may be a bit early :-)

Hello,

I'm using tess4j to make a webapp that scans PDF bills or pictures to extract a certain reference number. I developed the webapp on Windows where everything is working fine so far ( although i have some image pre-processing to implement). Since the webapp will be running on a Linux server i'm running some test on a Debian system. I have compiled tesseract libraries and leptonica and also installed ghostscript and the required libraries. When testing an image i get the correct results but when it comes to testing pdf I have an invalid calling convention 63 error. I've browsed on various post related to this subject and applied the suggested solutions. My system: Debian 8 Jessie Tesseract 3.04.01 Leptonica 1.72 The webapp is running with Tomcat 8.0.33

*What I have done so far to fix this issue: *

• Switched the JNA from 4.2.2 to 4.1.0 in the provided libs for Ghost4j https://github.com/zippy1978/ghost4j/issues/44
• Switched Ghostscript version from 9.18 to 9.16 according to this post https://github.com/nguyenq/tess4j/issues/30#issuecomment-185533296

Regardless of all that, the issue persists. So I would appreciate some pointers on how to fix this issue. Is it related to Debian ? Is there something I have done wrong ? Maybe there's a library I failed to install. The ocr works for pictures so my suspicion is that the problem is linked to PDF conversion.

The next option I will try is to make the tests on a CentOS system. But I thought that if I could get it running on Debian it should be running anywhere. I'd like to point out that I'm a student so I apologize if I seem unclear or lack some technicalities. This my internship subject so I'm doing my best to get it working. If needed I'll provided additional information.

Thank you

I'm trying to extract text from PDFs using tess4j but it's outputting EE ee EE EE EE ee and similar text, even though windows is significantly better.

I had the same problem on windows but moving gsdll64.dll to src/main/resources fixed the issue for me and the output is almost 100% accurate. I can't seem to figure out how to fix this on macOS.

I added -Djna.library.path=/usr/local/lib to my args and it still doesn't work even though both ghostscript and tesseract is installed via homebrew and should have a symlink to /usr/local/lib. I also tried moving libtesseract.4.dylib and libgs.9.52.dylib to src/main/resources as well and tried moving them to a darwin folder under resources doesn't help either.

Am I doing something wrong or does tess4j just not work as well on macOS compared to windows?

The PDFs I'm using is also very clear without any noise or marks.

Tess4J: 4.5.2 Tesseract: 4.1.1 Leptonica: 1.80.0 Ghostscript: 9.5.2

Hi! I experience an interesting behavior with Tess4J running under CentOS. My environment: CentOS7 (4 CPU with AVX2 and etc.) Tomcat 8.5 JRE 1.8.191-b12 latest Tesseract4 installed with yum latest Tess4J invoked by servlet

I take the same file and serially trigger recognition multiple times. And timing is always the same: First and second runs last for 2 second The third and below take 12 second

Application restart doesn't have any effect (12s for first and below) Tomcat restart forces the situation to repeat: 2s, 2s, 12s ...

When I run Tesseract from command line it is always fast with no performance degradation

When I deploy my application to Windows server and use dll, the timing is stable with no performance degradation.

Please, help!

I can give you all application sources including teamviewer connection

Hello, this is a great tool, thank you. We are using version 5.1.0. But why doesn't the text/string that is generated from doOCR() match text/string generated from createDocuments() / createDocumentsWithResults() ? We are inputting the same tiff file into both functions and the resulting text is different. Essentially, we want to know which one of these we should use, and if they were producing the same results, we could confidently choose either. But since, they don't, we need to decide which one to use (which one is better). We don't understand why they don't match exactly.

For example, a snippet of our code for createDocumentsWithResults():

List<RenderedFormat> listRF = new ArrayList<RenderedFormat>();
listRF.add(RenderedFormat.PDF);
listRF.add(RenderedFormat.TEXT);
aryStrFileInputPaths[0] = "<SOME_PATH>\\tiff1.tiff";
List<OCRResult> listOCRResult = tessInst.createDocumentsWithResults(aryStrFileInputPaths, aryStrFileOutputPaths, listRF, 0);
String strResultCreateDocs = listOCRResult.toString();

Note, aryStrFileInputPaths is a String Array with paths of the tiffs, and aryStrFileOutputPaths is a String Array of pdf filenames to be generated.

An example of our code for doOCR() is:

String strImagePagePathAndFileName = "<SOME_PATH>\\tiff1.tiff";
File fileObjImage = new File(strImagePagePathAndFileName);
String strResultDoOCR = tessInst.doOCR(fileObjImage);

The one change that strResultCreateDocs has is that it includes extra text like "[Average Text Confidence: 82% Words:" and "[Confidence: 82.831604 Bounding box: 100 313 2298 2906]". We understand these differences. Aside from those differences, we would expect an exact match of the text. But, in many cases, there are differences in text throughout the page.

Based on a previous response from an issue (https://github.com/nguyenq/tess4j/issues/154#issuecomment-503820107), it states "New APIs similar to createDocuments have been added to support buffered images as input."

But, that does not answer the question we have. Is createDocumentsWithResults() and doOCR() using a different engine to generate the OCR'd text, and if not, why does it generate different results? If there is a way to get them to generate the exact same text, any info on how to do that would be most appreciated. Thank you.

I am using createDocumentsWithResult to produce textOnly pdf from multipaged tiff and check ocr data(words count and confidence)

After recent update to latest version(used 4.5.5) I see minimum double processing time increase comparing to prev version.

This might probably be related to #233 fix because now all pages checked.

Is it possible to improve a code to work faster OR provide an alternative to produce textOnly pdf file without collecting OcrResult or specify amount of pages to collect ocr result from?

I can post some code snippets and doc sample later if required. Let me know if you need samples.

I'm developing a routine in my JAVA Web project (Using netbeans 13) where I extract the texts from a pdf. If it doesn't find a certain term, it converts the pdf to image and tries to extract the text with OCR tesseract. After several attempts I always got the same error regardless of the configuration I did. Following error:

Error opening data file tessdata/por.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory.
Failed loading language 'por'
Tesseract couldn't load any languages!

Caused by: java.lang.Error: Invalid memory access

I'm having difficulties configuring the library in my development environment because, unlike the tutorials where SpringBoot and Eclipse are used, I use Netbeans 13 and I have the following project structure:

[]1

First I added the dependency in pom.xml:

<!-- https://mvnrepository.com/artifact/net.sourceforge.tess4j/tess4j -->
        <dependency>
            <groupId>net.sourceforge.tess4j</groupId>
            <artifactId>tess4j</artifactId>
            <version>5.2.0</version>
        </dependency>

After that as indicated in some tutorials, I went to my tessdata folder which is in dependencies/Tes4j and copied the tessdata folder to the web-inf folder (I also tried to the resources folder).

Later I tried to configure the environment variable TESSDATA_PREFIX. I couldn't find information if this variable was to be defined in the windows system variables or if there is some other place in netbeans to define this. In my project structure I tried three definitions but none worked:

1. C:\Programacao\myProjectName\Tess4J
2. C:\Programacao\myProjectName\src\main\webapp\WEB-INF
3. C:\Programacao\myProjectName\src\main\webapp\resources

In the code of my method I tried to set the datapath passing only the name tessdata, data and I also tried to point out the paths above. Follow created method:

 public String extractText(Anexos anexo) throws Exception {
        File file = new File(anexo.getCaminho());
        PDDocument doc = PDDocument.load(file);

        System.out.println("=================================> Extraindo com pdfBox <=========================");
        PDFTextStripper estripador = new PDFTextStripper();
        estripador.setSortByPosition(false); 
        String pdfTexto = estripador.getText(doc);
        String line = "";

        line = pdfTexto.toLowerCase().replaceAll(AplicacaoBean.CARACTERES_ESPECIAIS_REGEX, "")
                .replaceAll("\\s", " ");
        
        if (line.contains("sped")) {
            return line;
        } else {

            PDFRenderer pdfRenderer = new PDFRenderer(doc);
            StringBuilder out = new StringBuilder();

            Tesseract tesseract = new Tesseract();
            tesseract.setLanguage("por");
            tesseract.setOcrEngineMode(1);

            Path dataDirectory = Paths.get("tessdata");
            tesseract.setDatapath(dataDirectory.toString());

            for (int page = 0; page < doc.getNumberOfPages(); page++) {
                BufferedImage bufferedImage = pdfRenderer.renderImageWithDPI(page, 300, ImageType.RGB);

                // Create a temp image file
                File tempFile = new File(file.getPath().replace(File.separator + anexo.getAnexo(), "") + File.separator + "tempfile_" + anexo.getAnexo().replaceAll("\\..*", "") + "_" + page + ".png");
                ImageIO.write(bufferedImage, "png", tempFile);
                String result = tesseract.doOCR(tempFile);
                out.append(result);

                // Delete temp file
                tempFile.delete();
            }

            line = out.toString().toLowerCase().replaceAll(AplicacaoBean.CARACTERES_ESPECIAIS_REGEX, "")
                    .replaceAll("\\s", " ");
        }

        return line;
    }

My tessdata folder:

[]2

My development environment:

Netbeans:13

JDK 15

tess4j:5.2.0

My doubts:

So I would like to know if this environment variable () is configured in windows variables, in netbeans or in some internal place in my code? Also, did I skip any steps? Do I need to download anything else? Please help me, I don't know what else to do!

I'm seeing an error in the ImageDeskew routine. The below sample code shows a rotation of -6.8 (the unredacted version shows -10) on the attached file even though it should be 0. Any idea why it’s not calculating correctly?

It seems to happen on somewhat sparse images like this, which understably makes it harder to figure out the orientation. I'm wondering if anything can be done to make it more accurate (note: sample file is a tif file, which I couldn't attach, so I zipped it)

public class GetAngle {

    private static double getAngle(Path sourceFile) throws IOException {
        BufferedImage bi = ImageIO.read(sourceFile.toFile());
        ImageDeskew id = new ImageDeskew(bi);
        double angle = id.getSkewAngle();
        if (angle < 1.0D && angle > -1.0D) {
            angle = 0.0D;
        } else {
            System.out.println("*** angle: " + angle);
        }

        return angle;
    }

    public static void main(String[] args) throws IOException {
        Path path = Paths.get( "/testFiles", "sample rotated image - Redacted.tif");
        System.out.println("*** path: " + path);
        System.out.println("*** getAngle: " + getAngle(path));

    }
}
