Prerequisites

Before diving into the tutorial, ensure you have the following prerequisites in place:

1. .NET Development Environment Setup

Ensure you have a working .NET development environment set up on your machine. You can download the latest version of the .NET SDK from the Microsoft website.

2. GroupDocs.Annotation for .NET Library

Download and install the GroupDocs.Annotation for .NET library from the provided download link. Follow the installation instructions to integrate the library into your project successfully.

3. Input Document

Prepare a sample document (e.g., “input.xlsx”) that you intend to annotate using GroupDocs.Annotation for .NET. Ensure the document is accessible from your project directory.

Import Namespaces

To begin, import the necessary namespaces into your project. These namespaces provide access to the classes and methods required to perform document annotation tasks effectively.

    pageNumber => new FileStream(Path.Combine("Your Document Directory", $"cells_page{pageNumber}.png"), FileMode.Create),
    (number, stream) => stream.Dispose()
);

Step 2: Define Worksheet Columns

previewOptions.WorksheetColumns.Add(new WorksheetColumnsRange("Sheet1", 2, 3));
previewOptions.WorksheetColumns.Add(new WorksheetColumnsRange("Sheet1", 1, 1));

Step 3: Initialize Annotator with Input Document

using (Annotator annotator = new Annotator("input.xlsx"))
{
    annotator.Document.GeneratePreview(previewOptions);
}

Step 4: Display Success Message

Console.WriteLine($"\nDocument previews generated successfully.\nCheck output in {"Your Document Directory"}.");
