AnalyzeBarcode Method

In This Topic

Description

This method has been deprecated. Use the AnalyzehDib and AnalyzeIPicture methods instead.

Syntax

Visual Basic
Public Sub AnalyzeBarcode( _ Optional ByVal X As Variant, _ Optional ByVal Y As Variant, _ Optional ByVal Width As Variant, _ Optional ByVal Height As Variant _ )

Parameters

X: The left edge coordinate, in pixels, of the region of interest.
Y: The top edge coordinate, in pixels, of the region of interest.
Width: The width, in pixels, of the region of interest.
Height: The height, in pixels, of the region of interest.

Remarks

This method has been deprecated. Use the AnalyzehDib and AnalyzeIPicture methods instead.

Note: Barcode area parameters are optional.

The AnalyzeBarcode method uses the ImageSource property to determine the source of the bitmap.

The AnalyzeBarcode method analyzes the entire bitmap unless a search region is defined by the input parameters. The analysis is faster if a search region is defined. If it is desired to search the entire image, the input parameters can be ignored in containers that support this. (ie Visual Basic). In containers that require the input parameters to be present, simply set all input parameters (X, Y, Width and Height) to zero.

Note: If the bitmap used for recognition is a DIB defined by the hDIB property, it is the responsibility of the caller to free this resource when analysis is complete, and the DIB is no longer needed.
