[Solved] Generate QR code with Javascript macros

[Dudette]

Hi guys,
I wanna generate QR code in libreoffice using JavaScript as that scenario:
1- select the image from browsing function that I implemented in JavaScript macros in Libreoffice.
2- take this image and process on it QR code generation then embedded this qrcode image on the original image.
the step one is done in javascript macros, but step 2 I don't know the start point of that specially using JavaScript.
any help for that ??

[Dudette]

PLZ any help as I searched a lot about this matter but found nothing
I found only javacsript normal not macros and when i run it through libreoffice macros it gives me errors
any suggestion ?

How about to use ImageIO of Java?

Code: Select all

importClass(Packages.java.io.File);
importClass(Packages.javax.imageio.ImageIO);

function test(image1, image2, out_path) {
    var bi = ImageIO.read(new File(image1));
    var g = bi.createGraphics();
    
    var bi2 = ImageIO.read(new File(image2));
    g.drawImage(bi2, 0, 0, null);
    
    ImageIO.write(bi, "png", new File(out_path));
}

var s1 = "/home/asuka/Pictures/Firefox_wallpaper.png";
var s2 = "/home/asuka/local/icons/sc/res/file.png";
var s3 = "/home/asuka/Desktop/bar/foo.png";
test(s1, s2, s3);

Thank U so much for ur reply
but it is not dynamic !! so I need for every new image to generate new QR code for it ?
Do U understand me ??

[hanya]

Draw your QR code on java.awt.image.BufferedImage and draw it on the background image.

[Dudette]

but how to generate the QR code in JavaScript macros ??

There are many QR code library if you do not want to write your own one.

There are many QR code library if you do not want to write your own one.

I know that but all of them attache the QR image to html or site and my need is to generate the QR image in the path on my laptop
could you help me for that and if you know such library doing that I'll be very thankful

Thank U so much I really appreciate your co-operation

Hi Hanya,
As I said before that I found hundred links of QR code generation in JavaScript but all of them attache the QR image on site or HTML
but this code it returns image on a path but it's 0 KB I don know why ? any help PLZ ?
I'll be very Thankful
Thanks in advance

Also I did some debugging and I the code is hanged at this function
// draw generated image on the back
g.drawImage(image, 0, 0, null);
and never continue


so where should be the problem ?
I appreciate your help

[hanya]

Could you tell me which version of the office version? If you have changed Rhino, its version too. My code works on Apache OpenOffice 3.4.1 with default Rhino 1.7R3.

[ame_sh90]

I'm working with Libreoffice 3.6 on Windows 7, and I haven't changed Rhino , but I don't know which version I have

[Dudette]

Thank U so much Hanya It works ^_^
Really I appreciate your co-operation

I'm speechless really Many Thanks Hanya ^_^ ^_^

[ame_sh90]

Hello Hanya

I have re-installed Libreoffice 4.0 and try the code again , but it still hanged at the same function "g.drawImage(image, 0, 0, null)"
I don't why the reason

Also I have checked Tools/Options Under Libreoffice / Advanced -> I found that I'm using JRE 1.7.0_09
is this Rhino ??
please any help ^_^

[hanya]

I could reproduce the same problem, it said the drawImage(image, 0, 0, null) is ambiguous on LibreOffice 4.0.4 64 bit with Java7.
Try:

Code: Select all

g.drawImage(image, null, 0, 0);

[ame_sh90]

Hanya I really don't know what to say .. just many thanks to you ^_^

please could you tell me how did you figure out that it's ambiguous ...is it an error at debugging or just from the documentation of the function in Libreoffice ?

[hanya]

Hi,

please could you tell me how did you figure out that it's ambiguous ...is it an error at debugging or just from the documentation of the function in Libreoffice ?

If the Rhino debugger window is opened, error messages are gone to somewhere else that you can not seen it, its a bug. So if you feel something wrong such as stopping the execution at middle of your code, close the debugger window and execute your script through Tools - Macros - Organize Macros - JavaScript - Execute button. If you do it, you can get the error message in the message dialog.

[ame_sh90]

Thank you ^_^
