Hi there,
I am getting very weird error. This occurs only in particular case. I am load multipage tif and converting to pdf using leadtools in .net v15. When I set
rasCodecs.Options.Pdf.Save.OwnerPassword = "passw0rd"; this is reulting in the above said error. without this property it works fine. Even with this property set, it is working for single page tiff. So I am just wondering whats going wrong. Below is error details: Please help.
Thanks,
Suresh
Code:
stream = new MemoryStream();
RasterCodecs.Startup();
RasterImageFormat imgFormat = GetRasFormatType(inputFile);
rasCodecs = new RasterCodecs();
RasterSupport.Unlock(RasterSupportType.PdfRead, pdfReadKey); //unlock PDF_READ
RasterSupport.Unlock(RasterSupportType.PdfSave, pdfSaveKey); //unlock PDF_SAVE
//int newRes = 200;
//rasCodecs.Options.Pdf.Load.XResolution = rasCodecs.Options.Pdf.Load.YResolution = newRes;
//rasCodecs.Options.Pdf.Load.DisplayDepth = 1;
//rasCodecs.Options.Pdf.Save.UserPassword = "passw0rd";
rasCodecs.Options.Load.Compressed = true;
rasCodecs.Options.Load.TiledMemory = true;
rasImage = rasCodecs.Load(inputFile); //load input file
// Draw text on PDF.
container = rasImage.CreateGdiPlusGraphics();
container.Graphics.SmoothingMode = SmoothingMode.None;
//container.Graphics.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAlias;
Brush br = new LinearGradientBrush(Point.Empty, new Point(200, 200), Color.Black, Color.Black);
Font textFont = new Font(FontFamily.GenericSansSerif, 15);
PointF point = new PointF(100, 50);
container.Graphics.DrawString("Generated By EIP Document Viewer at " + DateTime.Now.ToString(), textFont, br, point);
// Xolor-res it to 4 bits per pixel using the Netscape palette
// Note: Not sure how the lead tools stuff works. Without this "ColorResolutionCommand" code
// Generated pdf is displaying in inverted color like background is becoming black and letters
// are displaying in white. With this piece of code it worked fine.
ColorResolutionCommand cmd = new ColorResolutionCommand();
cmd.Mode = ColorResolutionCommandMode.InPlace;
cmd.BitsPerPixel = 4;
cmd.Order = RasterByteOrder.Rgb;
cmd.DitheringMethod = RasterDitheringMethod.None;
cmd.PaletteFlags = ColorResolutionCommandPaletteFlags.Optimized;
cmd.SetPalette(RasterPalette.Netscape());
cmd.Run(rasImage);
rasCodecs.Options.Pdf.Save.ModifyDocument = false;
rasCodecs.Options.Pdf.Save.PrintDocument = false;
rasCodecs.Options.Pdf.Save.ExtractText = false;

rasCodecs.Options.Pdf.Save.Use128BitEncryption = true;
rasCodecs.Options.Pdf.Save.OwnerPassword = "passw0rd";
rasCodecs.Save(rasImage, stream, imgFormat, 0, 1, -1, 1, CodecsSavePageMode.Overwrite);
pdfByteArray = stream.ToArray();
