Public API and Backward Incompatible Changes

1. Add Image Annotation

   Image annotation allows to add image within document page like shown at the picture below.

   

   IMPORTANT: On version 20.1 Image Annotation supported only in PDF, Words, Slides, Cells, Images documents.

   There is an ability to specify the next properties for ImageAnnotation type:

   • ImagePath - defines image local or remote path. Warning, if you use remote path - you need to remove http and https protocol, or www if it present. This error is now investigating.

   Not Correct: https://www.google.com.ua/images/branding/googlelogo/2x/googlelogo_color_92x30dp.png http://www.google.com.ua/images/branding/googlelogo/2x/googlelogo_color_92x30dp.png

   Correct: www.google.com.ua/images/branding/googlelogo/2x/googlelogo_color_92x30dp.png google.com.ua/images/branding/googlelogo/2x/googlelogo_color_92x30dp.png

   • Box - defines annotation position at document page; (image will be resized for your custom width and height)
   • Opacity - allows to set annotation opacity (present in all supported formats, examples of it you can see above);

   Follow these steps to add Image annotation to document:

   • Instantiate Annotator object with input document path or stream;
   • Instantiate ImageAnnotation object with desired properties (position, page number, etc);
   • Call Add method and pass ImageAnnotation object;
   • Call Save method with resultant document path or stream.

   The following code demonstrates how to add ImageAnnotation with remote ImagePath to the document:

   try (Annotator annotator = new Annotator("input.pdf")) {
       ImageAnnotation imageAnnotation = new ImageAnnotation();
       imageAnnotation.setBox(new Rectangle(100, 100, 100, 100));
       imageAnnotation.setOpacity(0.7);
       imageAnnotation.setPageNumber(0);
       imageAnnotation.setImagePath("www.google.com.ua/images/branding/googlelogo/2x/googlelogo_color_92x30dp.png");
       imageAnnotation.setAngle(100.0);
   
       annotator.add(imageAnnotation);
       annotator.save("result.pdf");
   }
   

   The result would be

2. Added new overloads for Get method

   On version 20.2 was added new overload of Annotator.Get method. It allows to get list of annotation of specific type

   try (Annotator annotator = new Annotator("annotated.pdf")) {
       List<AnnotationBase> tmp = annotator.get(AnnotationType.Area);
   }
   

3. Added new overloads for Remove method
   On version 20.2 Was added new overload of Annotator.Remove method. New overloads method allow to remove single Annotation or list of Annotations. Follow these steps to add annotation to document:

   • Instantiate Annotator object with input document path or stream;
   • Call Remove method and give them id, list of id’s, annotation to delete, or list of annotations
   • Call Save method to save changes
   1. Following code demonstrates overload how to remove Annotation from Document using annotation index:

   try (Annotator annotator = new Annotator("result.xlsx")) {
       annotator.remove(0);
       annotator.save("removed.xlsx");
   }
   

   2. Following code demonstrates overload how to remove Annotation from Document using Annotation Object:

   try (Annotator annotator = new Annotator("result.xlsx")) {
       List<AnnotationBase> tmp = annotator.get();
       annotator.remove(tmp.get(0));
       annotator.save("removed.xlsx");
   }
   

   3. Following code demonstrates overload how to remove some Annotations from Document using list of Id’s:

   try (Annotator annotator = new Annotator("result.xlsx")) {
       java.util.List<Integer> idList = new java.util.ArrayList<>();
       idList.add(0);
       idList.add(1);
       annotator.remove(idList);
       annotator.remove(idList);
       annotator.save("removed.xlsx");
   }
   

   4. Following code demonstrates how to remove some Annotations from Document using list of Annotations:

   try (Annotator annotator = new Annotator("result.xlsx")) {
       List<AnnotationBase> tmp = annotator.get();
       annotator.removeInternal(tmp);
       annotator.save("removed.xlsx");
   }
   

4. Starting from version 21.7 several Save methods overloads was added for user convenience
   Now you can call Empty Save to save documents as input file for annotator. If you need to add some options, you may call Save method with only one parameter - SaveOptions, it will do the same as empty but will consider your options.

   1. Method accepts SaveOption parameter

   try (Annotator annotator = new Annotator(_resultPath)) {
       SaveOptions saveOptions = new SaveOptions();
       saveOptions.setVersion(1);
       annotator.save(saveOptions);
   }
   

   2. Empty Save Method

   try (Annotator annotator = new Annotator(_resultPath)) {
       annotator.save();
   }
   

5. From this time Annotation Models overload the standard Equals method and also implement the IEquatable interface with the type of the class from which this method is called. Example how to use it:

   try (Annotator annotator = new Annotator("annotated_file.pdf")) {
       List<AnnotationBase> annotations = annotator.get();
       ImageAnnotation imageAnnotation = new ImageAnnotation();
       imageAnnotation.setBox(new Rectangle(100, 100, 100, 100));
       imageAnnotation.setOpacity(0.7);
       imageAnnotation.setPageNumber(0);
       imageAnnotation.setImagePath("www.google.com.ua/images/branding/googlelogo/2x/googlelogo_color_92x30dp.png");
       imageAnnotation.setAngle(100.0);
   
       annotator.add(imageAnnotation);
       annotator.save("result.pdf");
   
       for(int i = 0; i < annotations.size(); i++) {
           if (imageAnnotation.equals(annotations.get(i))) {
                   // Do some stuff here...
           }
       }
   }
   

6. Removed the deprecated ImportAnnotations property from the LoadOptions class because annotations are imported automatically. So, if before version 21.7 this code was correct:

   LoadOptions loadOptions = new LoadOptions();
   loadOptions.setPassword("password");
   loadOptions.setImportAnnotations(true);
   try (Annotator annotator = new Annotator("input.pdf", loadOptions)) {}
   

   Beginning with version 21.7, LoadOptions no longer has the ImportAnnotations property. The previous code needs to be changed. Example:

   LoadOptions loadOptions = new LoadOptions();
   loadOptions.setPassword("password");
   try (Annotator annotator = new Annotator("input.pdf", loadOptions)) {}
   

7. New WorksheetColumns property in PreviewOptions class that allows to specify the range of generated columns on a specified worksheet.

   Example how to use it:

   PreviewOptions previewOptions = new PreviewOptions(new CreatePageStream() {
       @Override
       public OutputStream invoke(int pageNumber) { //Stream => InputStream
           String pagePath = "/result_{pageNumber}.png";
           return File.create(pagePath).toOutputStream();
       }
   });
   
   previewOptions.getWorksheetColumns().add(new WorksheetColumnsRange("Sheet1", 2, 3));
   previewOptions.getWorksheetColumns().add(new WorksheetColumnsRange("Sheet1", 1, 1));
   
   try (Annotator annotator = new Annotator("input.xlsx")) {
       annotator.getDocument().generatePreview(previewOptions);
   }
   

8. Versions of Annotated files

   Every Time you Save file using Annotator.Save() method - you implicitly create a new version of the annotated file. Versions List stores not document, it keeps annotations that you add, remove, and change. So you can easy swap between different changes made with GroupDocs.Annotation. And of course you can set your version names. More information about how it works you can find in child Pages

   By default, they are created using unique GUID keys. Next, each aspect of using versions will be considered. The API execution logic has not changed, so you do not need to change your code to use it as before. By default, the latest version is loaded without your fate (that is, you will not notice the difference with previous releases).

   1. Backward Compatibility

   The update is fully compatible with previous and next updates (The latest saved version will be used), however, using versions on previous versions is not possible and the list of versions in this document will not be changed. And If you update file from 20.4+ using 20.2 and lower few times, after loading this document on 20.4+ only last changes will be added as new version.

   2. Add Version with custom name

   If you want to swap between versions easily you might need to have ability to set custom versions names.

   Here the code that demonstrates how to save version with custom name:

   try (Annotator annotator = new Annotator("input.pdf")) {
       AreaAnnotation areaAnnotation = new AreaAnnotation();
       areaAnnotation.setBox(new Rectangle(100, 100, 100, 100));
       annotator.update(areaAnnotation);
       SaveOptions saveOptions = new SaveOptions();
       saveOptions.setVersion("CUSTOM_VERSION" );
       annotator.save("result.pdf", saveOptions);
   }
   

   Version Property type is object, so it support any type, and you can use any variable as version variable
   3. Get List of All version keys on a document

   If you don’t know what versions were added earlier or want to know versions count Here the code that demonstrates how to get list of versions keys:

   try (Annotator annotator = new Annotator("result.pdf")) {
       List<Object> versionKeys = annotator.getVersionsList();
   }
   

   Annotator.GetVersionList() returns list of objects because it supports any type of key. But if you used some specified keys as string - you can convert it.
   4. Get List of Annotations using version key

   If you need to get List of Annotations you can use Annotator.GetVersion() method Here code that demonstrates how to get list of annotations from individual version

   try (Annotator annotator = new Annotator("result.pdf")) {
       List<AnnotationBase> versionKeys = annotator.getVersion("CUSTOM_VERSION");
   }
   

   GetVersion method supports any type, and you can use any variable as version variable.
   5. Load Document of custom Version

   Using LoadOptions.Version you can load previous versions of annotated document. Here the code that demonstrates how load version using version name:

   LoadOptions loadOptions = new LoadOptions();
   loadOptions.setVersion("CUSTOM_VERSION");
   try (Annotator annotator = new Annotator("input.pdf", loadOptions)) {
       annotator.save("result_loaded.pdf");
   }
   

   Version Property type is object, so it support any type, and you can use any variable as a version.

9. Added RenderComments Property to PreviewOptions If you need not to generate comments on image preview you may use RenderComments property

   This feature is only supported for Word processing documents.

   Default value is true. If it is not needed to display replies and comments at the page preview - set RenderComments property to false (replies and comments still will be stored inside document).
   Please notice, that RenderComments value will impact any document comments (doesn’t matter if they were added by GroupDocs.Annotation or some other application). Here the code that demonstrates how display image preview without comments:

   Annotator annotator = new Annotator("inputPath");
   PreviewOptions previewOptions = new PreviewOptions(new CreatePageStream() {
       @Override
       public OutputStream invoke(int pageNumber) {
           String pagePath = resultPath.replace("result.pdf", "/result_{pageNumber}.png");
           return File.create(pagePath).toOutputStream();
       }
   })
   previewOptions.setPreviewFormat(PreviewFormats.PNG);
   previewOptions.setRenderComments(false);
   annotator.getDocument().generatePreview(previewOptions);
   

10. Add PagesInfo property to IDocumentInfo PagesInfo represents list of PageInfo objects which store information about each page.

    Now PageInfo have two properties - Width and Height in pixels. This properties works with all formats except Email And Html that doesn’t have height and width so the won’t store them and will be empty. All pages width and height will be same in all formats except Cells, so you can use size of first element as size of all document.

    Here code that demonstrates how to get Document width and Height:

    Annotator annotator = new Annotator("input.docx");
    IDocumentInfo info = annotator.getDocument().getDocumentInfo();
    int width = info.getPagesInfo().get(0).getWidth();
    int height = info.getPagesInfo().get(0).getHeight();
    

11. Added Angle property for ImageAnnotation To set a custom angle for ImageAnnotation, you can use the new Angle property. Angle is measured in degrees.

    Example how to use it:

    ImageAnnotation imageAnnotation = new ImageAnnotation();   
    imageAnnotation.setBox(new Rectangle(100, 100, 100, 100));
    imageAnnotation.setOpacity(0.7);
    imageAnnotation.setPageNumber(0);
    imageAnnotation.setImagePath("image.png");
    imageAnnotation.setAngle(90.0);
    

12. Added horizontal and vertical alignment for Watermark To set Horizontal and Vertical Alignments for WatermarkAnnotation, you can use Alignment properties.

    WatermarkAnnotation watermarkAnnotation = new WatermarkAnnotation();
    watermarkAnnotation.setVerticalAlignment(VerticalAlignment.Bottom);
    watermarkAnnotation.setHorizontalAlignment(HorizontalAlignment.Left);
    

13. Added text horizontal alignment for TextField To set a text horizontal alignment you can use the TextHorizontalAlignment property.

    TextFieldAnnotation textFieldAnnotation = new TextFieldAnnotation();
    textFieldAnnotation.setTextHorizontalAlignment(HorizontalAlignment.Left);
