Implementation Guide

Hide Comments During PDF Conversion

This feature enables you to convert a presentation into a PDF while hiding comments, ensuring they don’t appear in the output file.

Step 1: Define Load Options

Firstly, define load options that specify how comments should be handled during conversion. By setting CommentsPosition to None, we ensure comments are hidden.

Func<LoadContext, LoadOptions> getLoadOptions = loadContext => new PresentationLoadOptions
{
    CommentsPosition = PresentationCommentsPosition.None // Hide comments.
};

Step 2: Initialize Converter

Initialize the converter with your input file and the custom load options. This step prepares the document for conversion.

string outputFolder = "YOUR_OUTPUT_DIRECTORY";
string outputFile = System.IO.Path.Combine(outputFolder, "converted.pdf");

using (Converter converter = new Converter(inputFile, getLoadOptions))
{
    // Conversion logic follows.
}

Step 3: Set PDF Convert Options

Define the conversion options specific to PDF. This sets up how your document will be formatted in the output file.

PdfConvertOptions options = new PdfConvertOptions();

Step 4: Perform Conversion

Finally, execute the conversion process from presentation to PDF using the configured options.

converter.Convert(outputFile, options);

Troubleshooting Tips: Ensure that your input files are accessible and paths are correctly specified. Check for any exceptions thrown during initialization or conversion for clues on resolving issues.

Practical Applications

  1. Corporate Reports: Convert internal presentations to PDFs for distribution without revealing comments.
