In the post "QR code: Encode and Decode QR code on linux command line" we saw usage of a command based tool to create QR codes in linux. Let us have a look at a GUI based tool for the same.
QTQR is gui a tool to create QR (Quick Response) code. We will need to install the tool qtqr
Once installed we can launch the tool from GUI in debian under Applications->graphics->QTQR
We can launch it from terminal using the command qtqr
This will launch a window as shown below.
To create a QR code we can choose what kind of string we want to encode using the pull down menu at the left top as shown below.
Once selected we can enter the text in the text below at the left and then click on "save QR code" at the right bottom and save the QR image.
The QR image for the text "Hello" would look as below.
To decode a QR code using QTQR click on decode at the right corner. While selecting decode we can either choose a file or choose an image being viewed by a webcam. To test the decode, point to the same QR image of "hello" that we created above and click on open.
As we can see the tool has correctly decoded the image.
