Hi,
My requirement is to display barcode on screen and user can take a print of
that screen.
I am using java and jsp.
I am able to display barcode successfully on screen. But when i take a print
of that and scan it, the barcode is not recognized by the barcode
readers/scanners. If i see the printout closely, i could make out that the
lines of barcode are distorted a bit.
My code is:
Barcode objBarcode = new Barcode39();
objBarcode.setBarHeight(55);
objBarcode.setCode(123456789098765);
Image objImage = objBarcode.createAwtImage(Color.BLACK, Color.WHITE);
BufferedImage objBufferedImage = new BufferedImage(300,
75, BufferedImage.TRANSLUCENT);
Graphics2D objGraphics2D = objBufferedImage.createGraphics();
objGraphics2D.drawImage(objImage, 0, 0, 300, 55, null);
objGraphics2D.setColor(Color.BLACK);
Font objFont = new Font("monospaced", Font.PLAIN, 12);
objGraphics2D.setFont(objFont);
String strBarcodeText = "* 123456789098765 *";
FontMetrics objFontMetrics = objGraphics2D.getFontMetrics();
Rectangle2D area = objFontMetrics.getStringBounds(strBarcodeText,
objGraphics2D);
objGraphics2D.drawString(strBarcodeText, (int) (objBufferedImage
.getWidth() - area.getWidth()) / 2, (int) (objBufferedImage
.getHeight() - 5));
response.setHeader("Cache-Control", "no-store");
response.setHeader("Pragma", "no-cache");
response.setDateHeader("Expires", 0);
response.setContentType("image/png");
final OutputStream outputStream = response.getOutputStream();
ImageIO.write(objBufferedImage, "png", outputStream);
outputStream.flush();
outputStream.close();
Please help me.
I tried open source JBarcodeBean. With this i am able to display barcodes as
the barcode scanners/readers recognize the barcodes generated by
JBarcodeBean.
I would like to get same results with iText also. Please help me.
