Hi,

here is a small demo file that show how to generate QR codes and even read them from a container field.

http://www.bh-a.com/index.php?option=com_content&view=article&id=88&Itemid=84&lang=en

(requires ScriptMaster )

Brilliant stuff....

Thanks.

BUT

I transferred it to my Scriptmaster file and downloaded the latest zxing and it returns QR codes which are white on black

Any idea why??

import java.awt.image.BufferedImage

import com.google.zxing.qrcode.QRCodeWriter

import com.google.zxing.common.BitMatrix

import com.google.zxing.BarcodeFormat

import com.google.zxing.client.j2se.MatrixToImageWriter



mtx = new QRCodeWriter().encode (input, BarcodeFormat.QR_CODE, 500 , 500)

image = MatrixToImageWriter.toBufferedImage(mtx)

return image

Had to reverse the j2se method to make it work properly. Wierd

//import com.google.zxing.client.j2se.MatrixToImageWriter

 

 

int WHITE = 0xFFFFFF

writer =  new QRCodeWriter()

m = new QRCodeWriter().encode (input, BarcodeFormat.QR_CODE, w , h)

image = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB)

for (x in 0..<w) {

for (y in 0..<h) {

   image.setRGB(x, y, m.get(x, y) ? WHITE : 0)

  } //end for

} //end for

hi John

are you on MacOS Lion? I heard there are some problems there...

No, 10.6.8

It works if I fire up your file first and run the script from in there, but if I ran it at all from the SM demo file I keep it reversed and then affected your file until FM was restarted

I have used two QR Code barcode generators recently. One is Java QR Code barcode generator SDK, another one is ASP.NET QR Code barcode generator SDK. They are easy to use. Share with you all.

actually,i've just generated qr code in vb.net from ka, In the beginning,i thought it's very hard for me,but when i follow the guide and do step by step,it 's not so difficult as i thought! but as for the reader for qr code ,i've no idea about that. is there any other resources?

I have used the QRCode plugin. It requires a purchase but its simplicity has made it well worth the price.

If it is just for generating QR code with simplicity and conveniences, then a free online QR code generator might be a better choice?

you can try some free .net qr code barcode reader dll, like zxing,
