Implementation Guide

Generate Preview Without Comments

Overview: This feature allows you to create document previews without annotations, ensuring a clean view. Ideal for sharing documents with stakeholders who need an uncluttered version.

Step 1: Create and Configure PreviewOptions

Start by configuring PreviewOptions:

// Define PreviewOptions to customize preview generation
PreviewOptions previewOptions = new PreviewOptions(pageNumber =>
{
    // Output path for each page's image file, using page number in the filename
    var pagePath = $"YOUR_OUTPUT_DIRECTORY\result{pageNumber}.png";
    return File.Create(pagePath);
});

Explanation: Here, PreviewOptions is configured to generate PNG images for specified document pages. The callback function dynamically creates an output path using the page number.

Step 2: Set Preview Format and Pages

// Specify preview image format as PNG
previewOptions.PreviewFormat = PreviewFormats.PNG;

// Define which pages of the document to preview
previewOptions.PageNumbers = new int[] { 1, 2, 3, 4, 5, 6 };

Explanation: We set PreviewFormat to PNG for high-quality image output. The array in PageNumbers specifies which pages to include.

Step 3: Ensure Comments Are Not Rendered

// Disable rendering of comments in the preview
previewOptions.RenderComments = false;

Explanation: Setting RenderComments to false ensures that no annotations are included, keeping previews focused on content.

Step 4: Generate the Document Preview

Finally, generate the previews using the configured options:

// Execute preview generation based on specified options
annotator.Document.GeneratePreview(previewOptions);

Troubleshooting Tip: If you encounter file path errors, ensure your output directory exists and has write permissions.

Practical Applications

  1. Client Presentations: Share unannotated versions of documents with clients for a clear overview.
  2. Internal Reviews: Quickly distribute clean document snapshots to team members for review.
  3. Automated Reporting: Integrate this feature into reporting systems that require document previews without clutter.

Performance Considerations

To optimize performance:

  • Limit the number of pages you preview at once, especially with large documents.
  • Use appropriate image formats and resolutions to balance quality and file size.
  • Manage memory efficiently by disposing of resources properly after use.
