Provides options for converting files into PDF.

public class RasterizationOptions

Constructors

Name Description
RasterizationOptions() Initializes a new instance.

Properties

Name Description
Compliance { get; set; } Gets or sets the PDF Compliance level.
Enabled { get; set; } Gets or sets a value indicating whether all pages in the document need to be converted to images and put in a single PDF file. TRUE by default, set to FALSE in order to avoid rasterization.
HasAdvancedOptions { get; } Gets an indicator, which is true if advanced rasterization options are set.
PageCount { get; set; } Gets or sets the number of pages to be converted into PDF.
PageIndex { get; set; } Gets or sets the index of the first page (0-based) to convert into PDF.

Methods

Name Description
AddAdvancedOption(AdvancedRasterizationOptions) You can use this method to register an advanced rasterization option to apply.
AddAdvancedOption(AdvancedRasterizationOptions, Dictionary<string, string>) You can use this method to register an advanced rasterization option to apply.

Examples

The following example demonstrates how to set options for the rasterization process.

    using (var redactor = new Redactor("SomePresentation.pptx"))
    {
        // redact sensitive data on the first slide 
    
        var rasterizationOptions = new RasterizationOptions();
        rasterizationOptions.PageIndex = 0;
        rasterizationOptions.PageCount = 1;
        rasterizationOptions.Compliance = PdfComplianceLevel.PdfA1a;
        using (var stream = File.Open(Path.Combine(@"C:\Temp", "PresentationFirstSlide.pdf")))
        {
            redactor.Save(stream, rasterizationOptions);
        }
    }

The following example demonstrates how to apply the advanced rasterization options with default settings.

    using (Redactor redactor = new Redactor(@"C:\sample.docx"))
    {
      // Save the document with default options (convert pages into images, save as PDF)
      var so = new SaveOptions();
      so.Rasterization.Enabled = true;
      so.RedactedFileSuffix = "_scan";
      so.Rasterization.AddAdvancedOption(AdvancedRasterizationOptions.Border);
      so.Rasterization.AddAdvancedOption(AdvancedRasterizationOptions.Noise);
      so.Rasterization.AddAdvancedOption(AdvancedRasterizationOptions.Grayscale);
      so.Rasterization.AddAdvancedOption(AdvancedRasterizationOptions.Tilt);
      redactor.Save(so);
    }

The following example demonstrates how to apply the border advanced rasterization option with custom settings.

    using (Redactor redactor = new Redactor(@"C:\sample.docx"))
    {
      // Save the document with a custom border
      var so = new SaveOptions();
      so.Rasterization.Enabled = true;
      so.RedactedFileSuffix = "_scan";
      so.Rasterization.AddAdvancedOption(AdvancedRasterizationOptions.Border, new Dictionary<string, string>() { { "border", "10" } });
      redactor.Save(so);
    }

The following example demonstrates how to apply the noise advanced rasterization option with custom settings.

    using (Redactor redactor = new Redactor(@"C:\sample.docx"))
    {
      // Save the document with the custom number and size of noise effects
      var so = new SaveOptions();
      so.Rasterization.Enabled = true;
      so.RedactedFileSuffix = "_scan";
      so.Rasterization.AddAdvancedOption(AdvancedRasterizationOptions.Noise, 
          new Dictionary<string, string>() { { "maxSpots", "150" }, { "spotMaxSize", "15" } });
      redactor.Save(so);
    }

The following example demonstrates how to apply the tilt advanced rasterization option with custom settings.

    using (Redactor redactor = new Redactor(@"C:\sample.docx"))
    {
      // Save the document with the custom tilt effect
      var so = new SaveOptions();
      so.Rasterization.Enabled = true;
      so.RedactedFileSuffix = "_scan";
      so.Rasterization.AddAdvancedOption(AdvancedRasterizationOptions.Tilt, 
          new Dictionary<string, string>() { { { "minAngle", "85" }, { "randomAngleMax", "5" } });
      redactor.Save(so);
    }
