Help -> Properties -> UseOverSampling

The Softek Barcode Reader SDK extracts barcode information from images and bitmaps.

UseOverSampling 

Overview

When UseOverSampling is TRUE the barcode reader samples 3 lines at a time (skipping 2 lines between each sample) and takes the average pixel value. This is useful for images containing both black and white speckles.   

Default value =     FALSE

Visual Basic using the OCX

[form.]SoftekBarcode.UseOverSampling= value

Visual Basic using the DLL

Private Declare Function stGetUseOverSampling Lib "SoftekBarcode" () As Boolean
Private Declare Function stSetUseOverSampling Lib "SoftekBarcode" (ByVal newValue As Boolean) As Boolean
stSetUseOverSampling (value)
value = stGetUseOverSampling ()

Visual Basic using COM

oBar = CreateObject("SoftekATL.Barcode")
.........
oBar.UseOverSampling = value
value = oBar.UseOverSampling

VB.Net using the DLL

Private Declare Function stGetUseOverSampling Lib "SoftekBarcode" () As Boolean
Private Declare Function stSetUseOverSampling Lib "SoftekBarcode" (ByVal newValue As Boolean) As Boolean
stSetUseOverSampling (value)
value = stGetUseOverSampling ()  

VB.Net using the SoftekBarcode Wrapper Class

Dim barcode As SoftekBarcode
..........
barcode.SetUseOverSampling(value)
value = barcode.GetUseOverSampling()

VB.Net using the SoftekBarcodeLib Managed Component

Dim barcode As SoftekBarcodeLib.BarcodeReader
Dim value As Bool
..........
barcode = New SoftekBarcodeLib.BarcodeReader()
..........
barcode.UseOverSampling = value
value = barcode.UseOverSampling

Visual C++ Using the OCX

BOOL GetUseOverSampling();
void SetUseOverSampling(BOOL value) ;

Visual C++ Using the DLL

BOOL __stdcall stGetUseOverSampling();
BOOL __stdcall stSetUseOverSampling(BOOL newValue);
