Setting Methods

As `PublicRuntimeSettings` Member

BarcodeColourModes can be set dynamically during runtime as a member of FurtherModes, which is a member of PublicRuntimeSettings struct, it is an array with 8 BarcodeColourMode Enumeration items.

Code Snippet in C++

//...other codes
PublicRuntimeSettings* pSettings = new PublicRuntimeSettings;
int errorCode = reader->GetRuntimeSettings(pSettings);
pSettings->barcodeColourModes[0] = BICM_DARK_ON_LIGHT;
reader->UpdateRuntimeSettings(pSettings);
reader->SetModeArgument("BarcodeColourModes", 0, "LightReflection", "1");
delete pSettings;
//...other codes

Remarks
GetModeArgument and SetModeArgument need to be called for getting and setting Arguments.
