For those following the 'using QR codes to pass Safari address & parameters into FM GO' to launch it discussions, I have done a quick script to create the QR code and return the image to a container using the itextpdf library..(needs 5.02.jar)

Only have a 'Touch' not a 'Phone' so if anyone want to test this works it would be brilliant...

//QRimg(fm_content)

//2010_09_25 JR

//v1

//takes path and text from fm_content and returns image to container

//requires itextpdf.jar 5.02 from itextpdf.com



import java.awt.image.*

import com.itextpdf.text.*

import com.itextpdf.text.pdf.*



qr = new BarcodeQRCode(fm_content, 1, 1, null)

img = qr.createAwtImage(java.awt.Color.BLACK, java.awt.Color.WHITE)

int w = img.getWidth()

int h = img.getHeight()

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

g2 = bi.createGraphics() 

g2.drawImage(img, 0, 0, w, h, null); 

g2.dispose()

return bi

Hi John,

I built this into an FM app I'm working on for a local museum that wants to add QR codes on the tags placed near the art objects, so that you can scan the code then have your browser take you to a web page with info about the object. Tested the QR code with an iPhone app called QRReader and it works well. Will test on an Android-based phone a little later and will post the results.

ANy chance you have a Datamatrix barcode working???

Just so happens I have updated my demo file this week

So here is is

Three layouts

FMP7 QR codes for use with Go

QR codes with a web address

Datamatrix code

Update

do not seem to be able to upload files

if anyone can fix this first then you can gladly have it.....

For now here is the code

//DataMXimg(fm_content)

//2011_05_15 JR

//v1

//takes content from fm_content and returns image to container

//requires min itextpdf.jar 5.02 from itextpdf.com



import java.awt.image.*

import com.itextpdf.text.*

import com.itextpdf.text.pdf.*



qr = new BarcodeDatamatrix()

qr.generate(fm_content)

img = qr.createAwtImage(Color.BLACK, Color.WHITE)

int w = img.getWidth()

int h = img.getHeight()

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

g2 = bi.createGraphics()

g2.drawImage(img, 0, 0, w, h, null)

g2.dispose()

return bi

Personally I love the zxing library to do that for me. http://code.google.com/p/zxing/

It can also read an image with a QR code in it (even when it is a picture of a building with a QR code on it) and returns the value of the QR code.

Awesome and thanks

if you have the sample file that would help thanks

attached...

EXCEPT you need to change the pdf extension to fp7 as it wont let me upload Filemaker file !!
