There are new functions in the PDF-417 barcode dynamic link library and ActiveX control for searching barcodes on the image using a median filter. If the image is noisy: for example scanned or faxed, the barcode algorithms may not find the barcode on the picture. In this case you should use the new barcode

functions, which using nonlinear median filter before detecting barcodes improves the ability to read.

A median filter operation on an image removes long tailed noise such as negative exponential and salt and pepper type noise from the image with a minimum blurring of

the image. Median filter is defined as :

Median(A) = median[A(x + i, y + j)]

where the coordinate (x+i, y+j ) is defined over the image A and the coordinate (i, j) is defined over the N x N size square mask.

Print2FTP transfers printed images to a specified FTP server. The application starts after the printing is finished, and will then copy all printed images to the FTP server. Print2FTP has C++, Visual Basic, C#, and J# versions in Visual Studio 2005, and Delphi in Borland Delphi 5.
 

The C++ program uses the BiPrint2FTP.dll dynamic link library for transferring files to the FTP server, while the Visual Basic, Delphi, C# and J# programs use the BiPrint2FTP.ocx ActiveX control. The dll and ocx were also written in Visual Studio 2005, and the dll uses the CInternetSession and CFtpConnection classes.
 

The entire source of the sample programs, BiPrintToFTP.dll and ocx is provided in the Printer Driver Resource Tool Kit.

If you want to configure the program, start the executable without parameters, you will get a box similar to Figure 1.
