Anotasi bentuk via Java

Anotasi bentuk dalam bagian ini mencakup jenis anotasi geometris seperti persegi, lingkaran, poligon, poliline, dan garis.

Menambahkan anotasi persegi, lingkaran, poligon, dan polilin

Gunakan contoh-conto ini ketika Anda perlu menempatkan anotasi geometris dengan warna khusus, opacity, data popup, atau array titik.

  1. Buka PDF sumber Document.
  2. Buat anotasi bentuk yang diperlukan dan konfigurasikan persegi panjangnya, titiknya, serta properti visualnya.
  3. Tambahkan anotasi ke halaman dan simpan dokumen yang diperbarui.

Mendapatkan anotasi persegi, lingkaran, poligon, dan polilin

Contoh-contoh ini memeriksa koleksi anotasi halaman dan mencetak persegi panjang anotasi geometris berdasarkan tipe.

  1. Buka PDF sumber Document.
  2. Iterasikan melalui anotasi halaman.
  3. Filter berdasarkan yang diperlukan AnnotationType nilai dan cetak persegi panjang.

    try (Document document = new Document(inputFile.toString())) {
        for (Annotation annotation : document.getPages().get_Item(1).getAnnotations()) {
            if (annotation.getAnnotationType() == AnnotationType.Square) {
                System.out.println(annotation.getRect());
            }
        }
    }
}

public static void circleAnnotationGet(Path inputFile) {
    try (Document document = new Document(inputFile.toString())) {
        for (Annotation annotation : document.getPages().get_Item(1).getAnnotations()) {
            if (annotation.getAnnotationType() == AnnotationType.Circle) {
                System.out.println(annotation.getRect());
            }
        }
    }
}

                System.out.println(annotation.getRect());
            }
        }
    }
}

Menghapus anotasi persegi, lingkaran, poligon, dan polyline

Gunakan contoh-contoh ini ketika anotasi bentuk dari jenis tertentu harus dihapus dari halaman.

  1. Buka PDF sumber Document.
  2. Kumpulkan anotasi dari tipe geometris yang diperlukan.
  3. Hapus anotasi yang dikumpulkan dan simpan file output.
public static void squareAnnotationDelete(Path inputFile, Path outputFile) {
    try (Document document = new Document(inputFile.toString())) {
        List<Annotation> toDelete = new ArrayList<>();
        for (Annotation annotation : document.getPages().get_Item(1).getAnnotations()) {
            if (annotation.getAnnotationType() == AnnotationType.Square) {
                toDelete.add(annotation);
            }
        }
        for (Annotation annotation : toDelete) {
            document.getPages().get_Item(1).getAnnotations().delete(annotation);
        }
        document.save(outputFile.toString());
    }
}

public static void circleAnnotationDelete(Path inputFile, Path outputFile) {
    try (Document document = new Document(inputFile.toString())) {
        List<Annotation> toDelete = new ArrayList<>();
        for (Annotation annotation : document.getPages().get_Item(1).getAnnotations()) {
            if (annotation.getAnnotationType() == AnnotationType.Circle) {
                toDelete.add(annotation);
            }
        }
        for (Annotation annotation : toDelete) {
            document.getPages().get_Item(1).getAnnotations().delete(annotation);
        }
        document.save(outputFile.toString());
    }
}

public static void polygonAnnotationDelete(Path inputFile, Path outputFile) {
    try (Document document = new Document(inputFile.toString())) {
        List<Annotation> toDelete = new ArrayList<>();
        for (Annotation annotation : document.getPages().get_Item(1).getAnnotations()) {
            if (annotation.getAnnotationType() == AnnotationType.Polygon) {
                toDelete.add(annotation);
            }
        }
        for (Annotation annotation : toDelete) {
            document.getPages().get_Item(1).getAnnotations().delete(annotation);
        }
        document.save(outputFile.toString());
    }
}

public static void polylineAnnotationDelete(Path inputFile, Path outputFile) {
    try (Document document = new Document(inputFile.toString())) {
        List<Annotation> toDelete = new ArrayList<>();
        for (Annotation annotation : document.getPages().get_Item(1).getAnnotations()) {
            if (annotation.getAnnotationType() == AnnotationType.PolyLine) {
                toDelete.add(annotation);
            }
        }
        for (Annotation annotation : toDelete) {
            document.getPages().get_Item(1).getAnnotations().delete(annotation);
        }
        document.save(outputFile.toString());
    }
}

Menambahkan anotasi garis

Contoh ini membuat anotasi garis dengan ujung panah, format batas, dan catatan popup.

  1. Buka PDF sumber Document.
  2. Buat LineAnnotation dengan titik awal dan akhir.
  3. Konfigurasikan tampilan, tambahkan popup, dan simpan dokumen.
public static void lineAnnotationAdd(Path inputFile, Path outputFile) {
    try (Document document = new Document(inputFile.toString())) {
        LineAnnotation lineAnnotation = new LineAnnotation(
                document.getPages().get_Item(1),
                new Rectangle(550, 93, 562, 439, true),
                new Point(556, 99),
                new Point(556, 443));
        lineAnnotation.setTitle("John Smith");
        lineAnnotation.setColor(Color.getRed());
        lineAnnotation.setStartingStyle(LineEnding.OpenArrow);
        lineAnnotation.setEndingStyle(LineEnding.OpenArrow);

        Border border = new Border(lineAnnotation);
        border.setWidth(3);
        lineAnnotation.setBorder(border);

        PopupAnnotation popup = new PopupAnnotation(
                document.getPages().get_Item(1),
                new Rectangle(842, 124, 1021, 266, true));
        lineAnnotation.setPopup(popup);

        document.getPages().get_Item(1).getAnnotations().add(lineAnnotation);
        document.save(outputFile.toString());
    }
}

Mendapatkan anotasi garis

Contoh ini membaca anotasi garis dan mencetak koordinat mulai dan akhir mereka.

  1. Buka PDF sumber Document.
  2. Iterasikan melalui anotasi halaman dan pilih AnnotationType.Line.
  3. Ubah tipe setiap kecocokan menjadi LineAnnotation dan cetak koordinatnya.
public static void lineAnnotationsGet(Path inputFile) {
    try (Document document = new Document(inputFile.toString())) {
        for (Annotation annotation : document.getPages().get_Item(1).getAnnotations()) {
            if (annotation.getAnnotationType() == AnnotationType.Line) {
                LineAnnotation la = (LineAnnotation) annotation;
                System.out.printf("[%s,%s]-[%s,%s]%n",
                        la.getStarting().getX(), la.getStarting().getY(),
                        la.getEnding().getX(), la.getEnding().getY());
            }
        }
    }
}

Menghapus anotasi garis

Gunakan pendekatan ini ketika anotasi garis harus dihapus dari halaman.

  1. Buka PDF sumber Document.
  2. Kumpulkan anotasi jenis AnnotationType.Line.
  3. Hapus anotasi yang dikumpulkan dan simpan dokumen.
public static void lineAnnotationsDelete(Path inputFile, Path outputFile) {
    try (Document document = new Document(inputFile.toString())) {
        Page page = document.getPages().get_Item(1);
        List<Annotation> toDelete = new ArrayList<>();
        for (Annotation annotation : page.getAnnotations()) {
            if (annotation.getAnnotationType() == AnnotationType.Line) {
                toDelete.add(annotation);
            }
        }
        for (Annotation annotation : toDelete) {
            page.getAnnotations().delete(annotation);
        }
        document.save(outputFile.toString());
    }
}
