Qr
Recently there were some topics about generating qr code offline and storing on device and thus I got idea to create Qr extension.
It basically creates and reads qr and bar codes offline from file.

A short documentation for the extension…
Bar Code Decoded
Event raised after decoding bar code with result and bar format
result ~ text
barFormat ~ text
Bar Code Generated
Event raised after GenerateBarCode method with response and filepath.If any error occurred during encoding then filePath value will be empty.
response ~ text
filePath ~ text
Barcode Formats
Returns a list of barcode formats which can be either encoded or decoded.Some formats can be encoded and decoded both like QR_CODE and CODE_39.
**Returns : List< String >
Decode Bar Code
Tries to decode barcode from given path.
filePath ~ text
Generate Bar Code
Generates barcode to given path with provided hints.
text ~ text
filePath ~ text
logoPath ~ text
height ~ int
width ~ int
fileFormat ~ text
barFormat ~ text
charset ~ text
margin ~ int
bgColor ~ int (Color)
barColor ~ int (Color)
Do you know any litterature about the exact algorithm converting text to QR code and v.v? (not mean sites or programs which convert input text).
I know the pattern for one-dimensioned bar code (EAN-13). If you could suggest something about QR code it would help me.
I mean the mathematical pattern of how the position of little squares in the image are transformed to text and vv.
Like in EAN-13 bar code, the set of numbers are evaluated are trace vertical bars of a certain width, separated by blanks of a specified width.
I was aware of it. It seems that algorithm of QR is much complicated than EAN-13. I didn’t manage to find any information more.
Anyway, thanks for your interest.
