Aspose Imaging Bildoptionskonstruktor

Question

Ich habe eine neue Version von As Pose Imaging Assembly installiert (Version 17.7.0.0) und ich muss den Code neu schreiben, so dass es neue Assembly unten unterstützt, wenn ich es neu schreiben muss
nicht Standardkonstruktors Ausgabe akzeptieren ist mit tIFF-Optionen Code

public void ImageToTIFF(string imagePath, string outputPath, string server, string folder, int sequenceNumber) 
    { 
     int page = 0; 
     using (Aspose.Imaging.Image inputImage = Aspose.Imaging.Image.Load(imagePath)) 
     { 
      page++; 
      Aspose.Imaging.ImageOptions.TiffOptions tiffSaveOptions = new Aspose.Imaging.ImageOptions.TiffOptions(); 
      tiffSaveOptions.Compression = Aspose.Imaging.FileFormats.Tiff.Enums.TiffCompressions.CcittFax4; 
      tiffSaveOptions.Photometric = Aspose.Imaging.FileFormats.Tiff.Enums.TiffPhotometrics.MinIsBlack; 
      tiffSaveOptions.BitsPerSample = new ushort[] {1}; 
      tiffSaveOptions.Palette = Aspose.Imaging.ColorPaletteHelper.CreateMonochrome(); 

      // Get the pixels of image by specifying the area as image boundary 
      Aspose.Imaging.RasterImage image = inputImage as Aspose.Imaging.RasterImage; 
      Aspose.Imaging.Color[] imageColors = image.LoadPixels(inputImage.Bounds); 
      int power; 
      for (int i = 0; i <= imageColors.Length - 1; i++) 
      { 
       try 
       { 
        power = (int)imageColors[i].R + (int)imageColors[i].G + (int)imageColors[i].B; 
        if (power < 380) 
        { 
         imageColors[i] = Aspose.Imaging.Color.White; 
        } 
        else 
        { 
         imageColors[i] = Aspose.Imaging.Color.Black; 
        } 
       } 
       catch (Exception ex) 
       { 
        Console.WriteLine("i: {0}, imageColors[i].R: {1}, imageColors[i].G: {2}, imageColors[i].B: {3}", i, imageColors[i].R, imageColors[i].G, imageColors[i].B); 
        Console.WriteLine("Error: {0}", ex.Message); 
        imageColors[i] = Aspose.Imaging.Color.White; 
       } 
      } 

      Aspose.Imaging.RasterImage imagePixels = inputImage as Aspose.Imaging.RasterImage; 
      imagePixels.SavePixels(inputImage.Bounds, imageColors); 
      inputImage.Save(outputPath + FileCreateTime(new FileInfo(imagePath)) + "_" + server + "_" + folder + "_" + sequenceNumber.ToString("D6") + "_" + page.ToString("D4") + ".tif", tiffSaveOptions); 
     } 
    }

ich Ihre Anforderungen beobachtet haben, und teilen möchten, dass es keine Standard leeren Konstruktor für TiffOptions Klasse in Aspose.Imaging zur Verfügung steht. Ich schlage vor, dass Sie versuchen, den folgenden alternativen Beispielcode an Ihrem Ende zu verwenden, um den Zweck zu erfüllen.

public void ImageToTIFF(string imagePath, string outputPath, string server, string folder, int sequenceNumber) 
{ 
    int page = 0; 
    using (Aspose.Imaging.Image inputImage = Aspose.Imaging.Image.Load(imagePath)) 
    { 
     page++; 
     Aspose.Imaging.ImageOptions.TiffOptions tiffSaveOptions = new Aspose.Imaging.ImageOptions.TiffOptions(TiffExpectedFormat.Default); 
     tiffSaveOptions.Compression = Aspose.Imaging.FileFormats.Tiff.Enums.TiffCompressions.CcittFax4; 
     tiffSaveOptions.Photometric = Aspose.Imaging.FileFormats.Tiff.Enums.TiffPhotometrics.MinIsBlack; 
     tiffSaveOptions.BitsPerSample = new ushort[] { 1 }; 
     tiffSaveOptions.Palette = Aspose.Imaging.ColorPaletteHelper.CreateMonochrome(); 

     // Get the pixels of image by specifying the area as image boundary 
     Aspose.Imaging.RasterImage image = inputImage as Aspose.Imaging.RasterImage; 
     Aspose.Imaging.Color[] imageColors = image.LoadPixels(inputImage.Bounds); 
     int power; 
     for (int i = 0; i <= imageColors.Length - 1; i++) 
     { 
      try 
      { 
       power = (int)imageColors[i].R + (int)imageColors[i].G + (int)imageColors[i].B; 
       if (power < 380) 
       { 
        imageColors[i] = Aspose.Imaging.Color.White; 
       } 
       else 
       { 
        imageColors[i] = Aspose.Imaging.Color.Black; 
       } 
      } 
      catch (Exception ex) 
      { 
       Console.WriteLine("i: {0}, imageColors[i].R: {1}, imageColors[i].G: {2}, imageColors[i].B: {3}", i, imageColors[i].R, imageColors[i].G, imageColors[i].B); 
       Console.WriteLine("Error: {0}", ex.Message); 
       imageColors[i] = Aspose.Imaging.Color.White; 
      } 
     } 

     Aspose.Imaging.RasterImage imagePixels = inputImage as Aspose.Imaging.RasterImage; 
     imagePixels.SavePixels(inputImage.Bounds, imageColors); 
     inputImage.Save(outputPath + FileCreateTime(new FileInfo(imagePath)) + "_" + server + "_" + folder + "_" + sequenceNumber.ToString("D6") + "_" + page.ToString("D4") + ".tif", tiffSaveOptions); 
    } 
} 

Ich hoffe, dass die geteilten Informationen hilfreich sein werden.
