06-05-2008, 3:31 Andrew Polden Joined on 06-08-2006 Posts 11 "Feature not supported", PdfCompressor.Write Hi. I'm evaluating the LT15 PDF plugin for C# within a WPF application and I'm having trouble writing out a PDF document. I've read elsewhere that this can be due to missing assembly references, however I am sure I've included all that are relevant. Because I am adding JPG images to the PDF, I have referenced: Leadtools.dll Leadtools.Codecs.dll Leadtools.Codecs.Cmp.dll Leadtools.Codecs.Pdf.dll Leadtools.Pdf.dll My code is:             RasterSupport.Unlock(RasterSupportType.PdfAdvanced, "");             RasterSupport.Unlock(RasterSupportType.PdfRead, "");             RasterSupport.Unlock(RasterSupportType.PdfSave, "");             // Load an image             RasterCodecs.Startup();             RasterCodecs codecs = new RasterCodecs();             codecs.ThrowExceptionsOnInvalidImages = true;             PdfCompressor pdfCompressor = new PdfCompressor();             PdfCompressorOptions pdfCompressorOptions = new PdfCompressorOptions();             PdfCompressorCompressionTypes compressionTypes = new PdfCompressorCompressionTypes();             //Sets compression types needed for each segment             compressionTypes.Comp1Bit = PdfCompressor1BitCompression.Zip1Bit;             compressionTypes.Comp2Bit = PdfCompressor2BitCompression.Lzw2Bit;             compressionTypes.CompPicture = PdfCompressorPictureCompression.JpgPic;             compressionTypes.QFactor = 2;             //Flags for used compression types should be set             compressionTypes.Flags = EnabledCompressionsFlags.EnableOneBit | EnabledCompressionsFlags.EnableTwoBit | EnabledCompressionsFlags.EnablePicture;             pdfCompressor.SetCompression(compressionTypes);             int pageNum = 1;             DirectoryInfo dInfo = Directory.CreateDirectory(InfoProvider.OutputPath);             FileInfo[] jpgFiles = dInfo.GetFiles(Path.GetFileNameWithoutExtension(InfoProvider.OutputFile) + "_*.jpg");             foreach (FileInfo jpgFile in jpgFiles)             {                 using (RasterImage image = codecs.Load(jpgFile.FullName))                 {                     pdfCompressor.Insert(image);                     //pdfCompressor.SegmentImage += new EventHandler<PdfCompressorSegmentImageEventArgs>(pdfCompressor_SegmentImage_PdfDocument);                 }                 jpgFile.Delete();             }             string filePath = InfoProvider.OutputPath + Path.GetFileNameWithoutExtension(InfoProvider.OutputFile) + ".pdf";             pdfCompressor.Write(filePath);             pdfCompressor.Dispose();             RasterCodecs.Shutdown();    Report

Please check 2 things: 1. If you run our pre-built C# Main demo shipped with the toolkit and open any image, can you save it as PDF using the File => Save menu? 2. If you use codecs.Save() instead of pdfCompressor.Write() to save the image as PDF, does it work? Adnan Ismail LEADTOOLS Technical Support    Report

06-05-2008, 20:27 Andrew Polden Joined on 06-08-2006 Posts 11 Re: "Feature not supported", PdfCompressor.Write Hi Adnan The CSPdfComp demo app works correctly, and I've looked at the code but I can't find anything I've missed - except that I have a WPF application and the demo is a WinForms app. This isn't likely to cause a problem is it? Codecs.Save also works correctly, however these is a huge difference in file size, even using RasterImageFormat.RasPdfJpeg. Regards, Andrew    Report

If you want to send the project, please put it in a ZIP or RAR file. About file size, you can use RasPdfLzw format instead of RasPdfJpeg to reduce the file size.
