Barcode, labelling and utility software

dBarScan-1D Java Class

The dBarScanJ Java Class was built using the Java 2 Platform, Standard Edition (J2SE) and the J2SE 1.4.2 SDK. The class allows barcode images to be decoded within the user’s own Java application. dBarScanJ accepts graphic images of the BufferImage type, scans an area of the image for a barcode, and decodes the barcode into its textual data.

Sample code

An example of the code required to decode an image from a file using the scan() method is:

scanner.setdImage(bi);
err= scanner.scan();
if (err<0)
{
            TextBox.setText(scanner.getoData()); // returns the barcode data
else
            TextBox.setText (“Barcode not detected”);

Features

• Image is passed directly to class as a BufferedImage, so may be taken from any Image-supporting source, including file (using ImageIO.read(file)) or in-memory Image.
