[moved] QR decoder

[kalidasan.selvaraj]

HI ,

Where can i find QR decoder source code for series 60 for symbian

[wizard_hu_]

Is this question really related to S60 5th edition, Touch UI or Sensors API-s?

Hi,

check http://discussion.forum.nokia.com/fo...d.php?t=108913
and sourceforge for GPL Java source code.

and sourceforge for GPL Java source code.

He does not like Java: http://discussion.forum.nokia.com/fo...ad.php?t=76813

touch API's only. i need to develop a QR code for decoding. thats is for series 60 3rd edition. that too in c++.

Hi,

I guess that accessing those forums you are developer. So if you face problems to find the free source - rewrite the Java code, which is publicly available to Symbian C++ - I have (really quickly) checked the code size of the QR decoder on sourceforge and it is pretty small - it should not be a problem.

Added later:
============
I have checked the wizard_hu_ link - he already suggested you to port the Java engine - did you at least tried it?

you mean that i need to convert the java code to c++??

can you please send me the link..

Hi,

hi,

I have found some qr source code which are all decoding the qrcode from the file. but i need like it sholud scan through camera and THen it should decode.

Is there any source code available or if i want to start from the scratch means where should i start from?

please guide me for this because am trying this for the past 1 week.am using carbide.c++ version 1.3 and series 60 sdk.

thanks in advance

If you ave a source which reads a file, you can simply locate where it reads from the file, and supply your data (from the memory) instead.

i have a decoder which scans the file from the memory.how to make it scan from the camera?it is in .sis format. i have unpacked the sis and i got some exe and RSc files. how and where to find the source code file for that?if i unpacked that i got rsc,dll and exe's. but i didnt get the source file

where to get that?

Hi,

Unless the application is open source and the source code is hosted publicly somewhere then you can't get the source code. There is no source in a SIS file, only compiled binaries (OK, you could try disassembling them and modifying the result but that would be much harder than writing a QR decoder!).

You need to get a camera example application and either capture images and decode the QR codes from there, or get the viewfinder bitmaps and try to decode those. There are example projects for the camera and other help in the discussion boards and Wiki already.

I think you should start by finding some actual source code for a QR decoder and making it work on Symbian with some test files. When you've got that working you can worry about converting it to decode from camera images.

i have searched in google but the source code is in java or in c#.

i need the source code in c++. please tell me if there is any link for that or i need to start from the scratch.

i have CameraApp example running in carbide for series 60.how to merge the Qr decoder code in this camera application?

if i need to start from th scratch means how to start that.

Hi,

What is wrong with the advice others have given to port the Java code to C++? It should be pure data processing so not too difficult???

To port Java code to C++ just go through line by line and change the Syntax where needed, most things map across quite well.

I think kalidasan.selvaraj is right. As proud C++ developers we should refuse to read code written in less inteligent languages and instead demand that somebody else translate them for us. The fact that it might be pure math code is not an excuse, that too can be written in C++ sintax and with nice comments or it should not be written at all.
