Hi Zhang,


We have reevaluated the presented scenario on our end with JDK 1.7.0_60 on Windows 7 Home Premium (64 bit). Unfortunately, we are still unable to observe the said exception, therefore we suspect the problem could be sample specific. Please provide your sample image that triggers the problem, so we may move forward to log problem in our bug tracking system for correction purposes.

Hi Zhang,


Thank you for providing the investigation material.

We have thoroughly checked the scenario on our end while using the latest version of Aspose.OCR for Java 1.9.0 against different version of JDK 1.7. Unfortunately, we are unable to replicate the said exception. Please see the attached snapshots for the output as well as the Java version on my machine.

Could you please confirm are you able to process any image with Aspose.OCR for Java? Attached to this post is a sample image (used in our Dashboard examples). Please execute your code code against this sample and see if you can reproduce the exception. In case the problem persists, please double check if your resource file is v1.9.0 compatible by downloading it again.

Hi Support Team,


I have redownloaded the resource and library file, but some error encountered. after debug, noticed the exception was throw from code “ImageStream.fromFile(imagePath);”, Do you know what’s the possible cause?

My source code:

// Set the paths
//String imagePath = “./samples/Sample.bmp”;
String imagePath=filePath;
System.out.println(“imagePath:” + imagePath);
String resourcesFolderPath = “C:\Users\zlin\Desktop\SLA ERS\POC-ASPOSE\Aspose.OCR.1.9.0.Resources.zip”;

// Create an instance of OcrEngine
OcrEngine ocr = new OcrEngine();
// Set Resources for OcrEngine
ocr.setResource(new FileInputStream(resourcesFolderPath));
// Set NeedRotationCorrection property to false
ocr.getConfig().setNeedRotationCorrection(false);

// Set image file
com.aspose.ocr.IImageStream iImageStream = ImageStream.fromFile(imagePath);
ocr.setImage(iImageStream);

// Add language
ILanguage language = Language.load(“english”);
ocr.getLanguages().addLanguage(language);

// Perform OCR and get extracted text
if (ocr.process()) {
System.out.println("\ranswer -> " + ocr.getText());
}
