using System.IO;

string documentPath = \@"YOUR_DOCUMENT_DIRECTORY";
DiagramLoadOptions loadOptions = new DiagramLoadOptions();
using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    // Your code here
}

Implementation Guide

Remove Shape by Index

This feature allows you to remove a shape from your diagram using its index. Here’s how you can implement it:

Overview

Removing shapes by their index is useful when dealing with diagrams where shapes are ordered or numbered.

Step-by-Step Implementation

1. Load the Diagram Start by loading your document with specified options:

string documentPath = \@"YOUR_DOCUMENT_DIRECTORY";
DiagramLoadOptions loadOptions = new DiagramLoadOptions();
using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    // Access the content of the diagram document.
    DiagramContent content = watermarker.GetContent<DiagramContent>();
    
    // Remove the first shape from the first page using its index.
    content.Pages[0].Shapes.RemoveAt(0);
    
    // Save the changes to a new file in the output directory.
    string outputDirectory = \@"YOUR_OUTPUT_DIRECTORY\\";
    string outputFileName = Path.Combine(outputDirectory, Path.GetFileName(documentPath));
    watermarker.Save(outputFileName);
}

Parameters Explained:

  • DiagramLoadOptions: Configures how your diagram is loaded.
  • content.Pages[0].Shapes.RemoveAt(0): Removes the shape at index 0 from the first page.

Troubleshooting Tips

  • Ensure the shape index exists to avoid exceptions.
  • Verify that the document path and output directory are correctly set.

Remove Shape by Reference

Alternatively, you can remove a shape using its reference. This method is beneficial when shapes have unique identifiers or properties.

Overview

Using references for removal ensures precision, especially in diagrams with numerous similar shapes.

Step-by-Step Implementation

1. Load the Diagram Follow similar steps as before but use shape references:

string documentPath = \@"YOUR_DOCUMENT_DIRECTORY";
DiagramLoadOptions loadOptions = new DiagramLoadOptions();
using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    // Access the content of the diagram document.
    DiagramContent content = watermarker.GetContent<DiagramContent>();
    
    // Remove the first shape from the first page by referencing it directly.
    content.Pages[0].Shapes.Remove(content.Pages[0].Shapes[0]);
    
    // Save the changes to a new file in the output directory.
    string outputDirectory = \@"YOUR_OUTPUT_DIRECTORY\\";
    string outputFileName = Path.Combine(outputDirectory, Path.GetFileName(documentPath));
    watermarker.Save(outputFileName);
}

Parameters Explained:

  • content.Pages[0].Shapes.Remove(...): Directly removes the referenced shape.

Troubleshooting Tips

  • Validate that the shape reference is valid.
  • Handle potential exceptions if the shape does not exist.

Practical Applications

Removing shapes can be applied in various scenarios:

  1. Project Documentation: Simplify diagrams by removing obsolete elements.
  2. Architectural Plans: Update floor plans by eliminating outdated features.
  3. Data Visualization: Clean up charts and graphs for better clarity.
  4. System Integration: Automate diagram updates within larger software systems.

Performance Considerations

To ensure optimal performance while using GroupDocs.Watermark:

  • Minimize the number of operations on large diagrams to reduce processing time.
  • Efficiently manage memory by disposing of objects properly after use.
  • Use asynchronous methods if available, for non-blocking operations.

Conclusion
