Implementation Guide

Extracting Shape Information from Word Documents

This feature allows you to parse through each shape within a Word document, capturing essential details like dimensions, type, position, and embedded images.

Initializing the Document and Loading Content

Load Your Document: Begin by initializing your Watermarker object with the target Word document.

using GroupDocs.Watermark.Contents.WordProcessing;

string documentPath = "YourDocument.docx";
var loadOptions = new WordProcessingLoadOptions();
using (var watermarker = new Watermarker(documentPath, loadOptions))
{
    // Get the content of the Word document.
    WordProcessingContent content = watermarker.GetContent<WordProcessingContent>();

    foreach (WordProcessingSection section in content.Sections)
    {
        foreach (WordProcessingShape shape in section.Shapes)
        {
            ProcessShape(shape);
        }
    }
}

Process Each Shape: For each shape, extract and display relevant properties.

void ProcessShape(WordProcessingShape shape)
{
    // Check if the shape is part of a header or footer
    if (shape.HeaderFooter != null)
    {
        Console.WriteLine("Shape is within a header/footer.");
    }

    // Display basic properties of the shape
    string shapeType = shape.ShapeType.ToString();
    double width = shape.Width;
    double height = shape.Height;
    bool isWordArt = shape.IsWordArt;
    float rotateAngle = shape.RotateAngle;
    string alternativeText = shape.AlternativeText;
    string name = shape.Name;
    double xPosition = shape.X;
    double yPosition = shape.Y;
    string text = shape.Text;

    Console.WriteLine($"Type: {shapeType}, Width: {width}, Height: {height}");

    // Check if the shape contains an image
    if (shape.Image != null)
    {
        double imageWidth = shape.Image.Width;
        double imageHeight = shape.Image.Height;
        int imageByteLength = shape.Image.GetBytes().Length;

        Console.WriteLine($"Image Width: {imageWidth}, Height: {imageHeight}");
    }

    // Display alignment properties of the shape
    string horizontalAlignment = shape.HorizontalAlignment.ToString();
    string verticalAlignment = shape.VerticalAlignment.ToString();

    Console.WriteLine($"HorizontalAlignment: {horizontalAlignment}, VerticalAlignment: {verticalAlignment}");
}

Key Configuration Options:

LoadOptions: Customize how documents are loaded, such as specifying password protection.
Shape Properties: Tailor which properties to extract based on your needs.

Troubleshooting Tips

Ensure all dependencies are correctly installed and paths are accurately specified.
Check the document’s structure; malformed sections may cause exceptions during extraction.

Practical Applications
