Prerequisites

Before starting, ensure you have the following:

  • Required Libraries: GroupDocs.Watermark for .NET (version 20.x or later)
  • Environment Setup: A development environment supporting .NET Framework or .NET Core
  • Knowledge Prerequisites: Basic understanding of C# and familiarity with diagram document structures

Setting Up GroupDocs.Watermark for .NET

To get started, install the GroupDocs.Watermark library. Here’s how:

Installation Methods

.NET CLI

dotnet add package GroupDocs.Watermark

Package Manager

Install-Package GroupDocs.Watermark

NuGet Package Manager UI Search for “GroupDocs.Watermark” and install the latest version.

License Acquisition

Acquire a free trial or temporary license to test GroupDocs.Watermark. For full access, consider purchasing a license from their official website. This enables you to explore all features without limitations.

Basic Initialization

Once installed, initialize the library in your project:

using GroupDocs.Watermark;

// Initialize Watermarker with your document path
Watermarker watermarker = new Watermarker("YOUR_DOCUMENT_DIRECTORY");

Implementation Guide

We’ll break down the implementation into key features: loading a diagram, iterating over pages and shapes, and saving changes.

Loading a Diagram Document

Overview Loading a diagram document is crucial for manipulation. This feature allows you to read your diagrams programmatically.

Implementation Steps

  1. Set Up Load Options

    using GroupDocs.Watermark.Contents.Diagram;
using GroupDocs.Watermark.Options.Diagram;

string documentPath = "YOUR_DOCUMENT_DIRECTORY"; // Replace with your file path
DiagramLoadOptions loadOptions = new DiagramLoadOptions();

  2. Load the Document

    using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    DiagramContent content = watermarker.GetContent<DiagramContent>();
}

Explanation: DiagramLoadOptions allows you to specify options for loading. The Watermarker class facilitates accessing the document’s content.

Iterating Over Diagram Pages and Shapes

Overview This feature enables detailed manipulation by traversing pages and shapes within a diagram.

Implementation Steps

  1. Iterate Through Pages

    using System.Drawing; // For Color class

foreach (DiagramPage page in content.Pages)
{
    for (int i = page.Shapes.Count - 1; i >= 0; i--)
    {
        foreach (FormattedTextFragment fragment in page.Shapes[i].FormattedTextFragments)
        {
            if (fragment.ForegroundColor.Equals(Color.Red) && fragment.Font.FamilyName == "Arial")
            {
                page.Shapes.RemoveAt(i);
                break;
            }
        }
    }
}

Explanation: This code snippet checks each shape’s text fragments for specific conditions (e.g., color and font type) and removes shapes that meet these criteria.

Saving the Modified Diagram Document

Overview After modifications, save your changes back to a file.

Implementation Steps

  1. Specify Output Path

    using System.IO;

string outputDirectory = "YOUR_OUTPUT_DIRECTORY"; // Replace with desired path
string outputFileName = Path.Combine(outputDirectory, Path.GetFileName(documentPath));

  2. Save the Document

    watermarker.Save(outputFileName);

Explanation: This step writes your changes to a new file in the specified directory.

Practical Applications

  1. Automated Diagram Updates: Automatically update diagrams based on data changes.
  2. Conditional Formatting: Apply conditional formatting rules across multiple diagrams.
  3. Batch Processing: Efficiently process and modify large batches of diagram files.
  4. Integration with Design Tools: Enhance design tools by integrating automated document manipulation features.
  5. Compliance Checks: Ensure diagrams comply with specific standards or guidelines.

Performance Considerations

  • Optimize Resource Usage: Minimize memory usage by disposing of objects properly.
  • Efficient Iteration: Use efficient loops and conditions to reduce processing time.
  • Best Practices: Follow .NET best practices for memory management, such as using using statements to handle resources.
