These details provide a comprehensive guide to setting up and using GroupDocs.Annotation Cloud SDK for Java, covering the essential requirements, installation steps, and security configurations.

Here are two of the most sellable code snippets extracted from the provided content. These snippets showcase essential functionality that would appeal to potential users looking to integrate annotation capabilities into their applications.

Sample Cloud Java Code to Add a Point Annotation

This snippet demonstrates how to add a point annotation to a document using the GroupDocs.Annotation Cloud SDK for Java. Point annotations are useful for marking specific points in a document with comments or notes.

// For complete examples and data files, please go to https://github.com/groupdocs-annotation-cloud/groupdocs-annotation-cloud-java-samples
String MyAppKey = ""; // Get AppKey and AppSID from https://dashboard.groupdocs.cloud
String MyAppSid = ""; // Get AppKey and AppSID from https://dashboard.groupdocs.cloud

Configuration configuration = new Configuration(MyAppSid, MyAppKey);
AnnotateApi apiInstance = new AnnotateApi(configuration);

// Create annotation/s.
AnnotationInfo[] annotations = new AnnotationInfo[1];
annotations[0] = new AnnotationInfo();

Point pt = new Point();
pt.setX(1.0);
pt.setY(1.0);
annotations[0].setAnnotationPosition(pt);

Rectangle r = new Rectangle();
r.setX(100.0);
r.setY(100.0);
r.setWidth(200.0);
r.setHeight(100.0);

annotations[0].setBox(r);
annotations[0].setPageNumber(0);
annotations[0].setType(TypeEnum.POINT);
annotations[0].setText("This is point annotation");
annotations[0].setCreatorName("Anonym A.");

// Create request object.
FileInfo fileInfo = new FileInfo();
fileInfo.setFilePath("Annotationdocs\\one-page.docx");

AnnotateOptions options = new AnnotateOptions();
options.setFileInfo(fileInfo);
options.setAnnotations(Arrays.asList(annotations));
options.setOutputPath("Output/one-page-annotated.docx");

AnnotateRequest request = new AnnotateRequest(options);

// Executing api method.
AnnotationApiLink result = apiInstance.annotate(request);
System.out.println("AddPointAnnotation: Point Annotation added: " + result.getTitle());

Sample Cloud Java Code to Add a TextHighlight Annotation

This code snippet shows how to add a text highlight annotation to a document. Highlighting text is a common annotation task, especially in review processes, and this snippet illustrates how it can be done programmatically.

// For complete examples and data files, please go to https://github.com/groupdocs-annotation-cloud/groupdocs-annotation-cloud-java-samples
String MyAppKey = ""; // Get AppKey and AppSID from https://dashboard.groupdocs.cloud
String MyAppSid = ""; // Get AppKey and AppSID from https://dashboard.groupdocs.cloud

Configuration configuration = new Configuration(MyAppSid, MyAppKey);
AnnotateApi apiInstance = new AnnotateApi(configuration);

// Create annotation/s.
AnnotationInfo[] annotations = new AnnotationInfo[1];
annotations[0] = new AnnotationInfo();

Rectangle r = new Rectangle();
r.setX(100.0);
r.setY(100.0);
r.setWidth(300.0);
r.setHeight(50.0);

annotations[0].setBox(r);
annotations[0].setPageNumber(0);
annotations[0].setType(TypeEnum.TEXT_HIGHLIGHT);
annotations[0].setText("This text is highlighted");
annotations[0].setCreatorName("Anonym A.");

// Create request object.
FileInfo fileInfo = new FileInfo();
fileInfo.setFilePath("Annotationdocs\\sample.docx");

AnnotateOptions options = new AnnotateOptions();
options.setFileInfo(fileInfo);
options.setAnnotations(Arrays.asList(annotations));
options.setOutputPath("Output/sample-annotated.docx");

AnnotateRequest request = new AnnotateRequest(options);

// Executing api method.
AnnotationApiLink result = apiInstance.annotate(request);
System.out.println("AddTextHighlightAnnotation: Text Highlight Annotation added: " + result.getTitle());
