The code you want would be like a OCR application, and would require a bit
of special processing to work.
Hi contrast, sharpening, THEN the character recognition, which should work
at different angles.
My point is this is not trivial code.
After I made these statements, I did a web
"bar code recognition" -- there seem to be quite a few SDK's for this
now. But that mean you would still have to assemble or compile in a low
level language or commission someone to build it it for LIvecode, that's
the critical path.
And if you want to 'roll your own from scratch' - take a look at this link
below which appears to be a complete description of how to interpret
barcodes in code:
Good psedocode examples. it almost looks "do-able" in Livecode.
