Very basic question (I think...)

in Programming Questions • 2 years ago

Hello community!

I'm swiss, so my mother tongue is German and my English is probably a little bit messed up. Sorry for that.

I'm still new at processing... I'd just like to have some help with the following problem:

I want the user to type in a short text or message which will be transformed into a QR-Code. Since it would be orbitally difficult to write sth that encodes it live I want the program to enter this particular message on http://qrcode.kaywa.com/ and to show the output (as a QR-Code).

It would be great if the user didn't even notice this (Like, typing in message>output QR-Code without anything in between to be noticed).

Thanks in advance for your help.

i can give some quick hints at least.
as you might noticed. you dont need to use the form on their website to enter the text and get the image.
You can just add the message to the imageurl and get the corresponding code.
so for example. for the Text "this is your text" the url would be :

http://qrcode.kaywa.com/img.php?s=8&d=Thisisyourtext

you can now programm a simple tool that let people enter some text. and after pressing submit or something like that.
you load the image like this

img = loadImage("http://qrcode.kaywa.com/img.php?s=8&d=Thisisyourtext ");

and then show it.
maybe you want some kind of blank image that is loaded on startup, so when the text is entered, the image gets updated.
should work this way.
