Hi,

I just clone your rep to my local to try out, but when I import the project into my eclipse, the POM editor shows a failure message says = Failure to transfer commons-collections:commons-collections:jar:3.2.1 from https bla bla bla...

So I went to maven repo, and found out that commons-collections already moved to common-collections4. I try to resolve this issue in local but I couldn't

Please advice, thanks Nguyen :)

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 #4
Results: same as (1)

Stack Trace:

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

We are just testing for the moment. The exception is:

Hello. I try to go from tess4j 2.0.1 to 3.1.0. I just changed the version of tess4j in my pom (Maven) and the java version to 1.7. Everything compile in a good way. The problem is that when I launch my tests in the same way as before (and it worked) tesseract did not find the language files.
The matter must come from the new version because when I go back to 2.0.1 in java 1.6 I do the work the same as before.

Whether tess4j thread-safe

How to include white spaces, tabs or special characters when looking for character coordinates??

I found out that I will get character coordinates using

int level = TessPageIteratorLevel.RIL_SYMBOL; (instead of RIL_WORD)

https://github.com/nguyenq/tess4j/blob/master/src/test/java/net/sourceforge/tess4j/TessAPI1Test.java#L465

The thing is that this will exclude other characters that are important to me. By important I mean I want to be able to provide text that make sense to humans too(with spaces, end lines, tabs).

So I really need to have the full OCR result of an image and also the coordinates of each character including special characters. Is this possible? Thanks.

User should get a hint, that Visual C++ Redistributable must be installed. Here a example running on Windows 7 with version 2.0.2-SNAPSHOT:

Is there any examples on how to usee tess4J to detect table?

Some images are crashing tess4j with the message:
start >= 0 && start + num <= length_:Error:Assert failed:in file ratngs.cpp, line 321,
causing java.lang.Error: Invalid memory access.
Processing the same image with tesseract from the commandline (generating hocr) works fine.
Any ideas?

System.out should be consequently replaced by a logging implementation / framework of our choice.
Imho sl4j and logback is the best out there for logging, see: http://logback.qos.ch/documentation.html

What do you think?

How to use multi thread in tess4j

Hay.

I have posted my question on Stackoverflow http://stackoverflow.com/questions/35295582/tess4j-memory-access-error-in-tess4j-java ... but I still can't solve the error... I tried to see if the problem in in bufferimage but the image bufft oky and the images on which its working or not are the same; same format, same resolution,

hear prints of image and Baytbuff of which program workse oky

Please help me... where can I search for bug.

The catch block in PdfUtilities.convertPdf2Png() is trying to log the Exception

https://github.com/nguyenq/tess4j/blob/master/src/main/java/net/sourceforge/tess4j/util/PdfUtilities.java#L107
logger.error(e.getCause().toString(), e);

e.getCause() may be null, calling toString on null is throwing NPE

Please check:
http://stackoverflow.com/questions/39504263/tesseract-error-net-sourceforge-tess4j-tesseract-null/39567186#39567186

https://github.com/tesseract-ocr/tesseract/releases/tag/3.04.00

The following code throws java.io.IOException: Unable to delete file: multipage_tif_example.pdf

File input = new File("multipage_tif_example.tif");
Tesseract1 instance = new Tesseract1();
instance.createDocuments(input.getPath(), input.getPath() , Arrays.asList(RenderedFormat.PDF));
File output = new File("multipage_tif_example.tif.pdf");
FileUtils.forceDelete(output);

Is there a handle kept by Tess4j on the output files?
Is there there a way to remove that handle?

Using PdfUtilities.convertPdf2Png(inputPdfFile) outputs this:

log4j:WARN No appenders could be found for logger (org.ghost4j.Ghostscript).
log4j:WARN Please initialize the log4j system properly.

The conversion works fine, but the warning is annoying :)

The example in https://github.com/nguyenq/tess4j/wiki/Code-Sample# should be updated.

At the startup of the application, if we add our own logback.xml inside a new project, we can see this warning:

|-WARN in ch.qos.logback.classic.LoggerContext[default] - Resource [logback.xml] occurs multiple times on the classpath.
|-WARN in ch.qos.logback.classic.LoggerContext[default] - Resource [logback.xml] occurs at [jar:file:/Users/[user]/.m2/repository/net/sourceforge/tess4j/tess4j/3.2.1/tess4j-3.2.1.jar!/logback.xml]
|-WARN in ch.qos.logback.classic.LoggerContext[default] - Resource [logback.xml] occurs at [file:/[project]/target/classes/logback.xml]

The result is pretty bad, since we lose control on our logging configurations, there's a workaroud, we can specify a distinct name for the config file etc., but it's not supposed to be like that.

In the pom.xml, it easy to exclude the file when packaging the jar:

                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-jar-plugin</artifactId>
                    <configuration>
                        <excludes>
                            <exclude>**/logback.xml</exclude>
                        </excludes>
                    </configuration>
                </plugin>

Hello!
Unfortunately I am not able to run tesseract through tess4j on Linux (CentOS).
I think that tesseract is being loaded correctly with JNA, but for some reason he can't find liblept.so.
Is it possible to somehow tell tesseract which is loaded through JNA where he should look for liblept.so?
Or maybe it would be possible to compile tesseract in such way that leptonica shared library wouldn't be needed at execution time?

NOTE1: I can't set LD_LIBRARY_PATH environment variable. It solves the problem but cannot be done on my system.
NOTE2: Leptonica is not installed on local machine.
NOTE3: I have compiled Tesseract from the source (tried github master branch and 3.02 from sourceforge).

We should add OSGI bundle support und deploy on maven central, here a request from Suvidh via the tesseract-ocr forum.

Hi

I am adding the below pom dependency to my project to download the ‘tess4j’ jar files.

It successfully download the jar files from the central repository and adds it to my class path. But it is not OSGI bundled jar it is a normal jar file.

To use this jar in my project it has to be OSGI bundled.

net.sourceforge.tess4j tess4j 1.3.0

Can I have the OSGI bundled Jar file.

Thanks

Suvidh

The output files for Tesseract1Test.testCreateDocuments() are 1348 bytes and is an invalid pdf.

Steps to reproduce:

1. Open your workspace
2. Run Tesseract1Test.testCreateDocuments()
3. check file size of test/test-results/docrenderer1-1.pdf
4. Open test/test-results/docrenderer1-1.pdf

Expected results:
file size of docrenderer1-1.pdf is larger than 1348 bytes and can open in Adobe reader successfully.

Actual results:
File size of test/test-results/docrenderer1-1.pdf is exactly 1348 bytes and cannot be opened.

Dropbox links to relevant files:

In the Release 2.0.0[1] the Dependencies are broken. The Jar-File must be overwritten by the "All-Jar" containing all the Dependencies before performing the Release see [2].

1: https://github.com/nguyenq/tess4j/releases/tag/tess4j-2.0.0
2: http://repo1.maven.org/maven2/net/sourceforge/tess4j/tess4j/2.0.0/

Due to the big size of the native libraries (gs*dll) of Ghost4J and the fact that pdfbox is written in pure java, we will be replacing the Ghost4J lib with pdfbox.

Hi, I want to build app for linux, and I see the some dependency on that library related to Win x86,x64? can I have working Jar file for Linux. may you have already a solution for that?

thanks

I want to develop a orc program on linux ubuntu, but I found the tess4j only support for windows;
My Question is that When the tess4j can support for linux or what can I do to support linux when using tess4j.

Just cloned the repo, built the .jar with

mvn assembly:single

Added the tess4j-2.0.0-SNAPSHOT-all.jar file to my classpath and tried to use it.
On the first call to

instance.doOCR(file);

it spits this out:

Error opening data file ./tessdata/eng.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
Failed loading language 'eng'
Tesseract couldn't load any languages!
AdaptedTemplates != NULL:Error:Assert failed:in file ..\..\classify\adaptmatch.cpp, line 174

Double checked and yes, I do have the TESSDATA_PREFIX set to:C:\Users\ribeirob\Applications\nguyenq\tess4j\src\main\resources\

Tess4J version - 3.1.0
Tesseract version - Tesseract Open Source OCR Engine v3.04.01 with Leptonica
Os - OSX 10.11.3 El Capitan

//TESS4J_FOLDER_PATH = "/usr/local/Cellar/tesseract/3.04.01_1/share/' - location lang .traineddata
instance = new Tesseract();
instance.setDatapath(TESS4J_FOLDER_PATH);
instance.setLanguage("chi_tra");

String result = "";
File imageFile = new File(filePath);
try {
     result = instance.doOCR(imageFile);
} catch (TesseractException e) {
    System.err.println(e.getMessage());
}
return result;

i got error

Failed loading language 'chi_tra'

Since #2 is the tessdata folder is the only resource / property that must be loaded / set in order to run tess4j.

For simplicity's sake, the default folder should be loaded automactly as the libs in #2.

WDYT?

When I run tesseract via cli, it automatically uses any .uzn file with the same name of the target image.

Example:
tesseract workingimage004.png output.txt -psm 4

If I have a workingimage004.uzn file in the same location of my workingimage004.png it will use it.

Tess4J ignores the uzn file.

Here is my code:

        Tesseract instance = Tesseract.getInstance();
        //In case you don't have your own tessdata, let it also be extracted for you
        File tessDataFolder = LoadLibs.extractTessResources("tessdata");

        //Set the tessdata path
        instance.setDatapath(tessDataFolder.getAbsolutePath());

        instance.setPageSegMode(4);
        try {
            String content = instance.doOCR(page);
        } catch (TesseractException e) {
            e.printStackTrace();
        }

Additional info:
Found the function that read and segments the image using a file UNLV at ccstruct\blread.cpp:36 (on tesseract source)

When running 'mvn clean package' I get this, any idea ?

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 :-)

Hi, I've enable HOCR output for Tess4j but I'm unable to find the resulting hocr file.

Where is the default output location for it?

Thanks

The non tess4j issue[1] on stack overflow brought to us the attention that it is currently unclear if the maven dependency jna 3.0.9 still needed is by tess4j or not.

Let's test and decide about it, thx.

1: http://stackoverflow.com/questions/28307976/nosuchfielderror-resource-prefix-with-a-maven-project-using-tess4j/28328252#28328252

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
  zippy1978/ghost4j#44
• Switched Ghostscript version from 9.18 to 9.16 according to this post
  #30 (comment)

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

Currently, only win32-x86 and win32-x86-64 are supported via .dlls that are in the distro, but it is possible to get tess4j working under linux via:

sudo apt-get install tesseract-ocr tesseract-ocr-vie
export TESSDATA_PREFIX=/usr/share/tesseract-ocr/

However, with code that uses tess4j, and is monitored with a linux continuous integration server that one does not have the ability to install libraries to, this is not possible. Hence, would it be possible to add {32.64} bit tesseract linux .so s to the repo?

Do someone have an easy fix, that does not invade our project to much for this penetrating log message from jbig2:

com.levigo.jbig2.util.log.JDKLogger info
Information: Globals not set.

Thanks in advance!

Hi I am having some issues after upgrading my app to tess4j 3.3.0. JNA wont find the dll no matter were I put them.

I am using Windows 2012 R2 (64bit)
I have installed:

• https://www.microsoft.com/en-us/download/details.aspx?id=48145

• And also tried: http://tess4j.sourceforge.net/tutorial/
  System.setProperty("jna.library.path", "32".equals(System.getProperty("sun.arch.data.model")) ? "lib/win32-x86" : "lib/win32-x86-64");

• In my code I am using:

  TessAPI api = TessAPI.INSTANCE;

I was using tess4j 3.0.0 before without any problems.

Is there any place where I can find more docs about how to point to the right location?

Do I need to install anything else?

Thanks!

i can not use tess4j for traditional chinese
it will show something like these:

Right now users have to extract the desired lib (dll) in order to be able to use the tess4j library properly.
We should load those libs depending on the OS automated into the java temp folder.

PoC already successful in the past.

Here are the steps

1. git clone https://github.com/nguyenq/tess4j.git
2. cd tess4j
3. mvn clean package (it will create both shaded and normal jar)
4. Install the normal jar into local repository
   mvn install:install-file -Dfile=target/tess4j-2.0.0-SNAPSHOT.jar -DpomFile=pom.xml

I created a simple repository to ease your testing
5. git clone https://github.com/brucardoso2/tess4jtest.git
6. mvn clean package (it will create both shaded and normal jar)

Now run the shaded jar with this image: https://www.dropbox.com/s/hhas9bddxpiaj97/workingimage001.png?dl=0
7. java -jar target/ShadedMaven-1.0-SNAPSHOT-shaded.jar workingimage001.png

It should output

Y

But tess4j outputs "Empty page !!"

I have no idea how tessearct could be stopped using ETEXT_DESC.cancel CANCEL_FUNC. An example like ProgressMonitor would be great.

I'm getting this error on an image:

I don't get this error when running tesseract on the command line:

As you can see, I'm trying to use the equations training data. It seems this error always happens when trying to use that training data. I have it loaded in my /usr/local/share/tessdata/equ.trainingdata from https://github.com/tesseract-ocr/tessdata/blob/master/equ.traineddata. I have not seen this error on other languages.

Any idea what's happening?

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

eng is ok.

also, i clone the tess4j project from github. and update junit test to set language chi_sim, put chi_sim.traineddata to src/main/resources, It appeared the same problem.

Hi everyone, I am currently working on a project using Tess4J. I want to change the symbol value in the TessResultIterator like this:

TessResultIterator ri = api.TessBaseAPIGetIterator(handle);
TessPageIterator pi = api.TessResultIteratorGetPageIterator(ri);
api.TessPageIteratorBegin(pi);
int level = TessPageIteratorLevel.RIL_SYMBOL;
do {
    Pointer ptr = api.TessResultIteratorGetUTF8Text(ri, level);
    String symbol = ptr.getString(0);
    float confidence = api.TessResultIteratorConfidence(ri, level);
    if (confidence < 80){
        Rectangle rect =    // get symbol rect
        String newSymbol = doMyStuff(rect);
        ptr.setString(0, newSymbol);    // something like this
    }
} while (api.TessPageIteratorNext(pi, level) == TRUE);

Pointer utf8Text = api.TessBaseAPIGetUTF8Text(handle);
String result = utf8Text.getString(0);    // get final result here

How can I achieve something like that? I searched the API and have found TessMutableIterator, but I can’t make it work.
Any help would be appreciated. Thanks for your attention.

As one can read here #10, there is currently no automated support for unz files.
I propose to add an automated support that, would check for unz files, parse them and populate a java.awt.Rectangle object and proceed with the process.

WDT?

This is maven breaking behaviour that should only be used for a final production application jar; not a library.
