Java如何在PDF添加注释

// Open the source PDF document

Document pdfDocument = new Document("input.pdf");

// Create annotation

TextAnnotation textAnnotation = new TextAnnotation(pdfDocument.getPages().get_Item(1), new com.aspose.pdf.Rectangle(200, 400, 400, 600));

// Set annotation title

textAnnotation.setTitle("Sample Annotation Title");

// Set annotation subject

textAnnotation.setSubject("Sample Subject");

textAnnotation.setState(AnnotationState.Accepted);

// Specify the annotation contents

textAnnotation.setContents("Sample contents for the annotation");

textAnnotation.setOpen(true);

textAnnotation.setIcon(TextIcon.Key);

Border border = new Border(textAnnotation);

border.setWidth(5);

border.setDash(new Dash(1, 1));

textAnnotation.setBorder(border);

textAnnotation.setRect(new com.aspose.pdf.Rectangle(200, 400, 400, 600));

// Add annotation in the annotations collection of the page

pdfDocument.getPages().get_Item(1).getAnnotations().add(textAnnotation);

// Save the output file

pdfDocument.save("output.pdf");
