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

SetScanRect(TopLeftX, TopLeftY, BottomRightX, BottomRightY, nMappingMode)

SetScanRect specifies the bounding rectangle in the image that should be searched for barcodes. To clear the rectangle and search the entire image set the rectangle to (-1, -1, -1, -1). The top left hand corner of an image is (0,0).

nMappingMode can have the following values:

• 0 = All measurements are in pixels.
• 1 = All measurements are a percentage of the width or height of the image. 

Visual Basic using the OCX

[form.]SoftekBarcode.SetScanRect(TopLeftX, TopLeftY, BottomRightX, BottomRightY, nMappingMode)

Visual Basic using the DLL

Private Declare Function stSetScanRect Lib "SoftekBarcode" (ByVal TopLeftX As Long, ByVal TopLeftY As Long, ByVal BottomRightX As Long, ByVal BottomRightY As Long, ByVal nMappingMode As Integer) As Bool

stSetScanRect(TopLeftX, TopLeftY, BottomRightX, BottomRightY, nMappingMode)

Visual Basic using COM

oBar = CreateObject("SoftekATL.Barcode")
.........
oBar.SetScanRect (TopLeftX, TopLeftY, BottomRightX, BottomRightY, nMappingMode) 

VB.Net using the DLL

Private Declare Function stSetScanRect Lib "SoftekBarcode" (ByVal TopLeftX As Long, ByVal TopLeftY As Long, ByVal BottomRightX As Long, ByVal BottomRightY As Long, ByVal nMappingMode As Integer) As Bool

stSetScanRect(TopLeftX, TopLeftY, BottomRightX, BottomRightY, nMappingMode)

strBarType  = stGetBarStringType(n)

VB.Net using the SoftekBarcode Wrapper Class

Dim barcode As SoftekBarcode

..........
barcode.SetScanRect (TopLeftX, TopLeftY, BottomRightX, BottomRightY, nMappingMode) 

VB.Net using the SoftekBarcodeLib Managed Component
