My current code writes a qr code but it over writes my file with just the qr code. I am not sure how to adjust the size of the qr code to be placed in one corner of the document rather than taking up the whole page. Also not sure if the RasterImage.Create means that it creates a new file with just the qr and discard my original file? Code: - Convert PDF to Bmp to add QR then saving back to PDF public void PDFFileExample() { RasterCodecs codecs1 = new RasterCodecs(); codecs1.Options.Pdf.InitialPath = @"C:\LEADTOOLS 18\Bin\Dotnet4\Win32"; codecs1.Dispose(); RasterCodecs codecs2 = new

We have legacy applications built using VB6. These applications are using lead-tools. Everything was perfectly working. We have another .NET process that optimizes the image (and do some water-marking) and save it in tiff format. Here is glimpse of .NET code, using (var bitmap = new Bitmap(contractWidth, contractHeight)) { using (var canvas = Graphics.FromImage(bitmap)) { canvas.InterpolationMode = InterpolationMode.Default; // Play with canvas canvas.Save(); } using (var stream = new MemoryStream()) { bitmap.Save(stream, ImageFormat.Tiff); return stream.ToArray(); } } When we save this in

I use LeadTools for scanning. I want to convert scanning image to byte. void twainSession_AcquirePage(object sender, TwainAcquirePageEventArgs e) { ScanImage = e.Image.Clone(); ImageSource source = RasterImageConverter.ConvertToSource(ScanImage, ConvertToSourceOptions.None); } How to convert ImageSource to Byte array? Unless you explicitly need an ImageSource object, there's no need to convert to one. You can get a byte array containing the pixel data directly from Leadtools.RasterImage using this code: int totalPixelBytes = e.Image.BytesPerLine * e.Image.Height; byte[] byteArray = new byte
