This parameter helps control the colour mode of the grayscale image. By default, the library can only locate the dark barcodes that stand on a light background. Assume your image has different features to default, this parameter may help configure the appropriate settings for your case.
It consisits of one or more modes, each mode represents a way to transform the grayscale image.
Keeps the original grayscale. This mode has the following arguments for further customizing.
Transforms the image to inverted grayscale. This mode has the following arguments for further customizing.
PublicRuntimeSettings
MemberGrayscaleTransformationModes
can be set dynamically during runtime as a member of FurtherModes
, which is a member of PublicRuntimeSettings
struct, it is an array with 8 GrayscaleTransformationMode
Enumeration items.
Code Snippet in C++
//...other codes
PublicRuntimeSettings* pSettings = new PublicRuntimeSettings;
int errorCode = reader->GetRuntimeSettings(pSettings);
pSettings->grayscaleTransformationModes[0] = GTM_ORIGINAL;
reader->UpdateRuntimeSettings(pSettings);
delete pSettings;
//...other codes
