interCharGapSize
[in][out] A value that defines the intercharacter gap size for Code 39 and
Codabar, which is typically quite small. Due to various barcode printing
technologies, this gap can grow larger than the maximum size allowed,
preventing the scan engine from decoding a barcode. If this problem occurs,
set it to "Large Intercharacter Gaps" to tolerate these out-of-specification
barcodes.
0x06* Normal intercharacter gaps
0x0A
Return Value If successful, it returns 1.
Otherwise, it returns 0.
Security Level 0 – This default setting allows the scan engine to
operate in its most aggressive state, providing sufficient security in
decoding most "in-spec" barcodes.
Security Level 1 – Select this option if misdecodes occur. This level
should eliminate most misdecodes.
Security Level 2 – Select this option if Security Level 1 fails to
eliminate misdecodes.
Security Level 3 – Select this option if Security Level 2 also fails to
eliminate misdecodes. However, selecting this option impairs the
decoding ability of the scan engine. If this level of security is
necessary, try to improve the barcode quality.
