Hi,
I'm trying to create a dynamic QR image on the screen.
Html
Wicket
form.add(new Image("image5", getImage5Resource()));
public ResourceReference getImage5Resource() {
return new ResourceReference(CompanyPanel.class, "image5")
{
@Override
public IResource getResource()
{
final BufferedDynamicImageResource resource = new
BufferedDynamicImageResource();
final BufferedImage image = new BufferedImage(300, 300,
BufferedImage.TYPE_INT_RGB);
String text = "";
String t="\n";
text = ""
+"BEGIN:VCARD"+t
+"VERSION:2.1"+t
+"NOTE:This works!"+t
+"CATEGORIES:BUSINESS,WORK"+t
+"END:VCARD";
drawQR( (Graphics2D)image.getGraphics() , text );
resource.setImage(image);
return resource;
}
};
}
void drawQR(Graphics2D graphics,String text)
{
try {
BitMatrix byteMatrix = new QRCodeWriter().encode(text,
BarcodeFormat.QR_CODE, 300, 300);
int matrixWidth = byteMatrix.getWidth();
//MatrixToImageWriter.writeToStream(byteMatrix, "png", new
FileOutputStream(new File("qrcode_test.png" +"")));
BufferedImage image = new BufferedImage(matrixWidth ,
matrixWidth,
BufferedImage.TYPE_INT_RGB);
graphics = image.createGraphics();
graphics.drawImage(image, 0, 0, 300, 300, null);
System.out.println(text);
} catch (WriterException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
