Eliminating unwanted annotations from PDF documents in your .NET applications becomes simpler with the GroupDocs.Annotation Cloud .NET SDK. Developers can effortlessly remove all kinds of PDF annotations, including highlights, arrows, strikeouts, or comments, right from their applications through straightforward REST API calls. This feature is especially beneficial when handling collaborative documents that require finalization, cleanup, or redaction prior to sharing or archiving.
When constructing a document management system, a PDF viewer/editor, or an automation tool for secure PDF handling, this SDK simplifies the process of ensuring your files are free from annotations and clutter. Its cloud-based design means there's no need to handle complicated PDF libraries or server-side infrastructure. The SDK integrates seamlessly into existing .NET projects and functions effortlessly with C# applications.
Utilizing this powerful .NET REST API allows you to manage annotations programmatically with accuracy—enhancing your workflow and providing improved, secure user experiences. If you're looking to incorporate PDF annotation capabilities into your .NET application or refine your current PDF cleanup process, this API delivers the dependability, speed, and versatility needed to execute the task effectively. Please consult this comprehensive guide for further information.
The subsequent C# code example will help you kickstart this capability quickly:
using System;
using GroupDocs.Annotation.Cloud.Sdk.Api;
using GroupDocs.Annotation.Cloud.Sdk.Client;
using GroupDocs.Annotation.Cloud.Sdk.Model;
using GroupDocs.Annotation.Cloud.Sdk.Model.Requests;
class Program
{
static void Main(string[] args)
{
// Initialize the API configuration with your credentials
string MyClientId = "your-client-id";
string MyClientSecret = "your-client-secret";
var configuration = new Configuration(MyClientId, MyClientSecret);
// Instantiate an AnnotateApi instance
var annotationApi = new AnnotateApi(configuration);
// Set the input file information
var fileInfo = new GroupDocs.Annotation.Cloud.Sdk.Model.FileInfo
{
FilePath = "SampleFiles/source.pdf"
};
// Extract the existing document annotations
var extractRequest = new ExtractRequest(fileInfo);
var annotationsResult = annotationApi.Extract(extractRequest);
// Build the list of extracted annotation IDs
var annotationIds = annotationsResult.Select(a => a.Id).ToList();
// Create remove options using the extracted IDs
var removeOptions = new RemoveOptions
{
FileInfo = fileInfo,
OutputPath = "annotation/output.pdf",
AnnotationIds = annotationIds
};
// Send a request to remove the annotations
var removeRequest = new RemoveAnnotationsRequest(removeOptions);
var result = annotationApi.RemoveAnnotations(removeRequest);
}
}
