Hi All !!!
We are looking for a lua library (source code included) that is able to decode a barcode or a QRCode (or both!!!) from an image. Usually this image comes out from the camera device, but it might be downloaded from a website too. Is there anyone here who is interested?
Looking forward to hear from you!

Vortika, we just submitted our first Xcode app that utilized QRCode/Barcode scanning functionality like you describe. It was rather straightforward to implement within that IDE but I haven’t done anything in LUA yet. You’re probably in the same boat…I do love that functionality; works great within my app. If I come across anything, I’ll ping you.

Not possible in LUA cuz you don’t have direct access to image. Without this you can’t do any Mathematical Morphology Filters like:
[cpp]
// searching for vertical lines
short[,] vse = new short[3, 3] {
{ 0, 1, 0 },
{ 0, 1, 0 },
{ 0, 1, 0 }
};
AForge.Imaging.Filters.HitAndMiss vFilter =
new AForge.Imaging.Filters.HitAndMiss( vse );
System.Drawing.Bitmap vImage = vFilter.Apply( image );
// searching for horizontal lines
short[,] hse = new short[3, 3] {
{ 0, 0, 0 },
{ 1, 1, 1 },
{ 0, 0, 0 }
};
AForge.Imaging.Filters.HitAndMiss hFilter =
new AForge.Imaging.Filters.HitAndMiss( hse );
System.Drawing.Bitmap hImage = hFilter.Apply( image );

Well Corona Enterprise users should be able to access 3rd party libraries making barcode reading possible, but most of us regular SDK people cannot do bar or QR codes. [import]uid: 19626 topic_id: 28270 reply_id: 114249[/import]
Using Corona Enterprise…
http://docs.coronalabs.com/native/enterprise/ios/index.html#native-api-ios
…might be the right solution to include some code like the gtatarkin’s one. Now my problems are two: time and money.
Time —> Corona Enterprise takes time because I have to debug twice using two difference platforms (lua+corona AND native coding)
Money —> Corona Enterprise is not for free (of course!) and it doesn’t seem cheap to me.
Anyway, is there anyone who is willing to develop a native component for iOS or Android or Both, to read barcode and qr-code?

Will have some time in next week so if you can wait a little longer you will got (I hope) offline qr code decoder. Bar code is much easer to do. [import]uid: 12704 topic_id: 28270 reply_id: 118359[/import]
Was this done? I need this as well. [import]uid: 97768 topic_id: 28270 reply_id: 142003[/import]

I am looking for a way to decode a QR code also with Corona Labs. Does anyone have an in-app solution? I can’t decode it on a server and get the results back. Need to do this offline.
Thanks!

I am also interested in decoding a QR Code.
