Annotation preview and code sample

// Create an instance of Reply class and add comments
Reply firstReply = new Reply();
firstReply.setComment("First comment");
firstReply.setRepliedOn(Calendar.getInstance().getTime());

Reply secondReply = new Reply();
secondReply.setComment("Second comment");
secondReply.setRepliedOn(Calendar.getInstance().getTime());

List<Reply> replies = new ArrayList<Reply>();
replies.add(firstReply);
replies.add(secondReply);

// Create an instance of AreaAnnotation class and set options
AreaAnnotation area = new AreaAnnotation();
area.setBackgroundColor(65535);
area.setBox(new Rectangle(100, 100, 100, 100));
area.setCreatedOn(Calendar.getInstance().getTime());
area.setMessage("This is area annotation");
area.setOpacity(0.7);
area.setPageNumber(0);
area.setPenColor(65535);
area.setPenStyle(PenStyle.Dot);
area.setPenWidth((byte) 3);
area.setReplies(replies);

// Create an instance of Annotator class
Annotator annotator = new Annotator("input.bmp");

// Add annotation
annotator.add(area);

// Save to file
annotator.save("output.bmp");
annotator.dispose();

Steps to Remove Annotations from DWG in Java

GroupDocs.Annotation makes it easier for Java developers to remove annotation details from DWG files within any Java-based application by implementing a few easy steps.

  • Create Reply objects with comment and date.
  • Instantiate SaveOptions object and set AnnotationTypes = AnnotationType.None.
  • Call save method with resultant document path or stream and SaveOptions object.

// Create an instance of Annotator class 
Annotator annotator = new Annotator("C://input.bmp");

// Remove annotation by set type None 
SaveOptions saveOptions = new SaveOptions();
saveOptions.setAnnotationTypes(AnnotationType.None);

// Save annotation to output file
annotator.save("C://output.bmp", saveOptions);
annotator.dispose();

Steps to Edit Annotations from DWG in Java

GroupDocs.Annotation makes it easier for Java developers to update various annotation properties from DWG files within any Java-based application by implementing a few easy steps.

  • Instantiate Annotator object with input document path or stream with instantiated LoadOptions with ImportAnnotations = true.
  • Create some AnnotationBase implementation and set Id of existed annotation (if annotation with that Id not found, nothing will be changed) or path list of annotations (all existed annotations will be removed).
  • Call update method of Annotator object with passed annotations.
  • Call save method with resultant document path or stream and SaveOptions object.

String outputPath = "UpdateAnnotation.bmp";

// Create an instance of Annotator class
Annotator annotator = new Annotator("input.bmp");

// Create an instance of Reply class for first example and add comments
Reply reply1 = new Reply();
reply1.setComment("Original first comment");
reply1.setRepliedOn(Calendar.getInstance().getTime());

Reply reply2 = new Reply();
reply2.setComment("Original second comment");
reply2.setRepliedOn(Calendar.getInstance().getTime());

java.util.List replies = new ArrayList();
replies.add(reply1);
replies.add(reply2);

// Create an instance of AreaAnnotation class and set options
AreaAnnotation original = new AreaAnnotation();
original.setId(1);
original.setBackgroundColor(65535);
original.setBox(new Rectangle(100, 100, 100, 100));
original.setCreatedOn(Calendar.getInstance().getTime());
original.setMessage("This is original annotation");
original.setReplies(replies);

// Add original annotation
annotator.add(original);
annotator.save(outputPath);
annotator.dispose();

LoadOptions loadOptions = new LoadOptions();

// Open annotated document
Annotator annotator1 = new Annotator(outputPath, loadOptions);

// Create an instance of Reply class for update first example
Reply reply3 = new Reply();
reply3.setComment("Updated first comment");
reply3.setRepliedOn(Calendar.getInstance().getTime());

Reply reply4 = new Reply();
reply4.setComment("Updated second comment");
reply4.setRepliedOn(Calendar.getInstance().getTime());

java.util.List replies1 = new ArrayList();
replies1.add(reply3);
replies1.add(reply4);

// Suggest we want change some properties of existed annotation
AreaAnnotation updated = new AreaAnnotation();
updated.setId(1);
updated.setBackgroundColor(255);
updated.setBox(new Rectangle(0, 0, 50, 200));
updated.setCreatedOn(Calendar.getInstance().getTime());
updated.setMessage("This is updated annotation");
updated.setReplies(replies1);

// Update and save annotation
annotator1.update(updated);
annotator1.save(outputPath);
annotator1.dispose();

Steps to Extract Annotations from DWG in Java

GroupDocs.Annotation makes it easy for Java developers to annotate documents and extract annotation information from DWG files within any Java-based application by implementing a few easy steps.

  • Create Reply objects with comment and date.
  • Instantiate LoadOptions object and call SetImportAnnotations with true argument.
  • Define variable with type List.
  • Call get method and return result to variable above.

// For using this example input file ("annotated.bmp") must be with annotations
LoadOptions loadOptions = new LoadOptions();

// Create an instance of Annotator class and get annotations
final Annotator annotator = new Annotator("annotated.bmp", loadOptions);
List annotations = annotator.get();

About DWG File Format

Files with DWG extension represent proprietary binary files used for containing 2D and 3D design data. Like DXF, which are ASCII files, DWG represent the binary file format for CAD (Computer Aided Design) drawings. It contains vector image and metadata for representation of contents of CAD files. There are free viewers available for viewing DWG files on Windows Operating System such as the Autodesk’s free DWG TrueView. There are other third party applications as well that support reaching DWG files.
