Receiving ArrayIndexOutOfBoundsException

Aspose.BarCode Product Family
1

Hi there,


The latest version 5.4.0 of the Java version fixes the problem of it getting slower and slower which is great.

I have a different issue now though:

To alleviate some of the problems of it taking a while to scan a full page (10 seconds at 200dpi) I take sections of the page where the barcodes are more likely to be and process those parts first.

It seems that some sizes of tif cause the component to except with an ArrayIndexOutOfBounds error.

I have attached a tif file which causes this to happen.

I get this call stack:
java.lang.ArrayIndexOutOfBoundsException: 122780

I hope you can find and fix this problem.

Hi Erik,

Thanks for your inquiry. I tested your sample bar code image against the latest build of Aspose.BarCode for Java 5.4.0. I’m unable to reproduce the error message on my side. Could you please share the environment details where it fails i.e. Operating System, IDE (Eclipse, Netbeans etc), JDK version. We’ll investigate the issue at our end and guide you accordingly. This will help us to replicate the problem on our side.

BarCodeReader reader = new BarCodeReader(“C:/temp/Error.tif”, BarCodeReadType.Code128);

while (reader.read())

{

System.*out* .println("Code :" + reader.getCodeText());

}

reader.close();

Result:

Code :0317666597

Hi Imran,


It works fine when reading the tif file directly, but not when it’s coming from a BufferedImage.

Here is some example code that reproduces the problem:


	/**

* Converts the supplied image into an {@link InputStream}

*

* @param image The {@link BufferedImage} convert

* @return {@link InputStream} of the supplied image

* @throws IOException

*/

private InputStream getImageInputStream(BufferedImage image) throws IOException {

ByteArrayOutputStream os = new ByteArrayOutputStream();

	ImageIO.write(image, "tiff", os);

	return new ByteArrayInputStream(os.toByteArray());
}

/**
 * Returns a list of BufferedImages, one for each page of the supplied tiff file
 * 
 * @param inFile The tiff file to process
 * @return List<bufferedimage>
 * @throws IOException
 */
private List<bufferedimage> getTiffPages(File inFile) throws IOException {
	List<bufferedimage> result = new ArrayList<bufferedimage>();
	
	Iterator<imagereader> readers = javax.imageio.ImageIO.getImageReadersBySuffix("tiff");
	if (readers.hasNext()) {
		ImageInputStream iis = javax.imageio.ImageIO.createImageInputStream(inFile);
		TIFFDecodeParam param = null;
		ImageDecoder dec = ImageCodec.createImageDecoder("tiff", inFile, param);
		// Get the page count of the tiff image
		int pageCount = dec.getNumPages();
		ImageReader _imageReader = (ImageReader) (readers.next());
		if (_imageReader != null) {
			_imageReader.setInput(iis, true);
			// Feed each page to the List of Buffered Images to return
			for (int i = 0; i < pageCount; i++) {
				result.add(_imageReader.read(i));
			}
		}
	}
	return result;
}

public void testScan() {
	List<bufferedimage> images;
	try {
		images = getTiffPages(new File("C:/temp/Error.tif"));
		for (int i = 0; i < images.size(); i++) {
			
			BarCodeReader reader = new BarCodeReader(getImageInputStream(images.get(i)), BarCodeReadType.Code128);
			reader.setExpectedBarCodeCount(1);

			if (reader.read()) {
				System.out.println("Code :" + reader.getCodeText());
			}
			
			reader.close();
		}
	} catch (IOException e) {
		e.printStackTrace();
	}
