Complementary Scanning functions

Automatic Linking of Combined Symbols
The CMOS Imager provides support for combining symbols. When scanning the following
combined symbols, the scanned data is stored in the internal buffer and all of the data from
combined symbols or all scanned symbols is combined and output.
Combined symbols can only be scanned when the decoding mode is set to "Normal Scan". Note
that combined symbols cannot be scanned in "Multi-step Scan" and "Package Scan" modes.

Code93 Code93 bar codes with a
space for leading data
Code49 Code49 bar codes with
lead starting with mode
1(M=1)
QR Code QR Code including
combination identifier.

Binary Data Scanning
The CMOS Imager is able to output data scanned from symbols not only in standard character
strings but also in binary data. It is therefore possible to scan binary data of encoded data, images
and audio as well as character strings delimited by NULL characters.
The function of the Imager Library relevant to the "Binary Data Scanning" is as follows.
IMGWaitForDecodeRaw : Carries out decoding symbol including its binary data.
When scanning symbols whose lead begins with a space, the
scanned data is stored in the internal buffer without being output.
Furthermore, when continuously scanning symbols starting with a
space, the data is combined in the internal buffer in the order that it
was scanned and is not output.
Finally, when scanning symbols other than those whose lead
begins with a space, it is combined with the internally stored data
and output.
Combination method same as for Code 93. Different to Code93 in
that the combined symbol lead starts with M=1.
Indicators displaying the number of symbol divisions and the
sequential number of the symbol are stored in the combined QR
Code. The decoder is therefore able to combine and output all data
in the order of the indicators upon scanning all of the symbols.
