    Hi, expert!
    I am doing some job on implement one kind of Bar Code Reader in symbian(QR code)

    I wonder to know:
    1. Is there a source code of such an application, or some docs on this topic?

    2. What should I take care when implementing such an app?

    Any docs or suggestions will be helpful.

    Re: Bar Code Reader question?

    I haven't seen any API, so maybe you could try google, and find applications that are already implementing this kind-of functionality. Then you could check what they require (like external optical lenses etc.) to get idea how they work.

    Basically what you need to do usually is to take a image, find black lines (dots in 2d bar codes) and figure then out what they mean. Also google for different bar code types, and you can see that some of them can infact fifure where the different parts should be in the image, as well as some have error correction math stuff added into them.
