Library CBarCode: General Functionality
CBarCode library functionality is similar to idData library. It extract the data from 2D, PDF417 type
bar code image. The library fetches the internal image (the last scanned image), process its graphic
information and activates its internal image analyzer. The resultant text is kept in internal data structure
ready to be retrieved by the ap plication.
Notice: The library processes only the last image that was recently scanned. The library does not
support external image file processing.
NOTE: The image MUST be scanned in 600dpi, gray scale (256 shades of gray) format.
