Anotasi Bentuk via Python

Contents
[ ]

Artikel ini menunjukkan cara bekerja dengan anotasi bentuk dalam dokumen PDF menggunakan Aspose.PDF untuk Python via .NET.

Skrip contoh menunjukkan beberapa alur kerja anotasi berbasis geometri:

  • anotasi garis
  • anotasi kotak
  • anotasi lingkaran
  • anotasi poligon
  • anotasi polyline

Anotasi Garis

Tambahkan Anotasi Garis

Contoh ini menambahkan anotasi garis ke halaman pertama dan mengonfigurasi gaya panah, lebar garis, serta jendela popup.

Buka PDF sumber

document = ap.Document(infile)

Buat dan konfigurasikan anotasi garis

line_annotation = ap.annotations.LineAnnotation(
    document.pages[1],
    ap.Rectangle(550, 93, 562, 439, True),
    ap.Point(556, 99),
    ap.Point(556, 443),
)

line_annotation.title = "John Smith"
line_annotation.color = ap.Color.red
line_annotation.width = 3
line_annotation.starting_style = ap.annotations.LineEnding.OPEN_ARROW
line_annotation.ending_style = ap.annotations.LineEnding.OPEN_ARROW

Lampirkan popup dan simpan PDF

popup = ap.annotations.PopupAnnotation(
    document.pages[1],
    ap.Rectangle(842, 124, 1021, 266, True),
)
line_annotation.popup = popup

document.pages[1].annotations.append(line_annotation)
document.save(outfile)

Contoh lengkap

def line_annotation_add(infile, outfile):
    document = ap.Document(infile)

    line_annotation = ap.annotations.LineAnnotation(
        document.pages[1],
        ap.Rectangle(550, 93, 562, 439, True),
        ap.Point(556, 99),
        ap.Point(556, 443),
    )

    line_annotation.title = "John Smith"
    line_annotation.color = ap.Color.red
    line_annotation.width = 3
    line_annotation.starting_style = ap.annotations.LineEnding.OPEN_ARROW
    line_annotation.ending_style = ap.annotations.LineEnding.OPEN_ARROW

    popup = ap.annotations.PopupAnnotation(
        document.pages[1],
        ap.Rectangle(842, 124, 1021, 266, True),
    )
    line_annotation.popup = popup

    document.pages[1].annotations.append(line_annotation)
    document.save(outfile)

Dapatkan Anotasi Garis

Untuk memeriksa anotasi garis, filter koleksi anotasi pada halaman pertama dan cast setiap hasil ke LineAnnotation sehingga Anda dapat membaca titik awal dan akhir nya.

Muat PDF dan kumpulkan anotasi garis

document = ap.Document(infile)

line_annotation = [
    cast(ap.annotations.LineAnnotation, annotation)
    for annotation in document.pages[1].annotations
    if annotation.annotation_type == ap.annotations.AnnotationType.LINE
]

Cetak koordinat garis

for annotation in line_annotation:
    print(
        f"[{annotation.starting.x},{annotation.starting.y}]"
        f"-[{annotation.ending.x},{annotation.ending.y}]"
    )

Contoh lengkap

def line_annotations_get(infile, outfile):
    document = ap.Document(infile)

    line_annotation = [
        cast(ap.annotations.LineAnnotation, annotation)
        for annotation in document.pages[1].annotations
        if annotation.annotation_type == ap.annotations.AnnotationType.LINE
    ]

    for annotation in line_annotation:
        print(
            f"[{annotation.starting.x},{annotation.starting.y}]"
            f"-[{annotation.ending.x},{annotation.ending.y}]"
        )

Hapus Anotasi Garis

Alur kerja ini menghapus semua anotasi garis dari halaman pertama dan menyimpan PDF yang telah diperbarui.

Temukan anotasi baris untuk dihapus

document = ap.Document(infile)
page = document.pages[1]

line_annotations = [
    annotation
    for annotation in page.annotations
    if annotation.annotation_type == ap.annotations.AnnotationType.LINE
]

Hapus anotasi dan simpan PDF

for annotation in line_annotations:
    page.annotations.delete(annotation)

document.save(outfile)

Contoh lengkap

def line_annotations_delete(infile, outfile):
    document = ap.Document(infile)
    page = document.pages[1]

    line_annotations = [
        annotation
        for annotation in page.annotations
        if annotation.annotation_type == ap.annotations.AnnotationType.LINE
    ]

    for annotation in line_annotations:
        page.annotations.delete(annotation)

    document.save(outfile)

Anotasi Kotak dan Lingkaran

Tambahkan Anotasi Kotak

Anotasi kotak sangat berguna untuk menandai area persegi panjang dalam sebuah dokumen. Contoh ini membuat anotasi kotak dengan pengaturan border, fill, dan transparansi.

Buka PDF dan buat anotasi kotak

document = ap.Document(infile)

square_annotation = ap.annotations.SquareAnnotation(
    document.pages[1],
    ap.Rectangle(60, 600, 250, 450, True),
)
square_annotation.title = "John Smith"
square_annotation.color = ap.Color.blue
square_annotation.interior_color = ap.Color.blue_violet
square_annotation.opacity = 0.25

Tambahkan anotasi dan simpan PDF

document.pages[1].annotations.append(square_annotation)
document.save(outfile)

Contoh lengkap

def square_annotation_add(infile, outfile):
    document = ap.Document(infile)

    square_annotation = ap.annotations.SquareAnnotation(
        document.pages[1],
        ap.Rectangle(60, 600, 250, 450, True),
    )
    square_annotation.title = "John Smith"
    square_annotation.color = ap.Color.blue
    square_annotation.interior_color = ap.Color.blue_violet
    square_annotation.opacity = 0.25

    document.pages[1].annotations.append(square_annotation)
    document.save(outfile)

Dapatkan Anotasi Persegi

Untuk memeriksa anotasi persegi, filter anotasi halaman pertama berdasarkan SQUARE ketik dan cetak setiap persegi panjang.

Muat dokumen dan kumpulkan anotasi persegi

document = ap.Document(infile)
square_annotations = [
    annotation
    for annotation in document.pages[1].annotations
    if annotation.annotation_type == ap.annotations.AnnotationType.SQUARE
]

Cetak persegi panjang anotasi

for annotation in square_annotations:
    print(annotation.rect)

Contoh lengkap

def square_annotation_get(infile, outfile):
    document = ap.Document(infile)
    square_annotations = [
        annotation
        for annotation in document.pages[1].annotations
        if annotation.annotation_type == ap.annotations.AnnotationType.SQUARE
    ]

    for annotation in square_annotations:
        print(annotation.rect)

Hapus Anotasi Kotak

Alur kerja ini menghapus semua anotasi persegi dari halaman pertama dan menyimpan dokumen.

Temukan dan hapus anotasi kotak

document = ap.Document(infile)
square_annotations = [
    annotation
    for annotation in document.pages[1].annotations
    if annotation.annotation_type == ap.annotations.AnnotationType.SQUARE
]

for annotation in square_annotations:
    document.pages[1].annotations.delete(annotation)

document.save(outfile)

Contoh lengkap

def square_annotation_delete(infile, outfile):
    document = ap.Document(infile)
    square_annotations = [
        annotation
        for annotation in document.pages[1].annotations
        if annotation.annotation_type == ap.annotations.AnnotationType.SQUARE
    ]

    for annotation in square_annotations:
        document.pages[1].annotations.delete(annotation)

    document.save(outfile)

Tambahkan Anotasi Lingkaran

Anotasi lingkaran menandai area bulat dalam PDF. Contoh ini menambahkan anotasi lingkaran dengan warna isi, opasitas, dan anotasi popup.

Buka PDF dan buat anotasi lingkaran

document = ap.Document(infile)

circle_annotation = ap.annotations.CircleAnnotation(
    document.pages[1],
    ap.Rectangle(270, 160, 483, 383, True),
)
circle_annotation.title = "John Smith"
circle_annotation.color = ap.Color.red
circle_annotation.interior_color = ap.Color.misty_rose
circle_annotation.opacity = 0.5

Lampirkan popup dan simpan PDF

circle_annotation.popup = ap.annotations.PopupAnnotation(
    document.pages[1],
    ap.Rectangle(842, 316, 1021, 459, True),
)

document.pages[1].annotations.append(circle_annotation)
document.save(outfile)

    )
    circle_annotation.title = "John Smith"
    circle_annotation.color = ap.Color.red
    circle_annotation.interior_color = ap.Color.misty_rose
    circle_annotation.opacity = 0.5
    circle_annotation.popup = ap.annotations.PopupAnnotation(
        document.pages[1],
        ap.Rectangle(842, 316, 1021, 459, True),
    )

    document.pages[1].annotations.append(circle_annotation)
    document.save(outfile)
