Replace(image)

img.Replace(image: Image) -> None

Mengganti konten ini Image node dengan konten dari yang lain Image node, dalam memori. Menyimpan kembali ke .one tidak didukung.

Accept(visitor)

img.Accept(visitor: DocumentVisitor) -> None

Contoh Penggunaan

Simpan semua gambar ke disk

from aspose.note import Document, Image

doc = Document("MyNotes.one")
for i, img in enumerate(doc.GetChildNodes(Image), start=1):
    filename = img.FileName or f"image_{i}.bin"
    with open(filename, "wb") as f:
        f.write(img.Bytes)
    print(f"Saved: {filename}  ({img.Width} x {img.Height} pts)")

Deteksi format gambar dari byte

doc = Document(“MyNotes.one”) for img in doc.GetChildNodes(Image): b = img.Bytes if b[:4] == b’\x89PNG’: fmt = “png” elif b[:2] == b’\xff\xd8’: fmt = “jpeg” elif b[:4] == b’GIF8’: fmt = “gif” else: fmt = “bin” print(f" {img.FileName!r} detected as {fmt}")


### Temukan semua gambar yang ditautkan

doc = Document("MyNotes.one")
for img in doc.GetChildNodes(Image):
    if img.HyperlinkUrl:
        print(f"  Linked image: {img.FileName!r} -> {img.HyperlinkUrl}")

Baca teks alt

doc = Document(“MyNotes.one”) for img in doc.GetChildNodes(Image): if img.AlternativeTextTitle or img.AlternativeTextDescription: print(f" Alt title: {img.AlternativeTextTitle!r}") print(f" Alt desc: {img.AlternativeTextDescription!r}")


### Periksa tag pada gambar

doc = Document("MyNotes.one")
for img in doc.GetChildNodes(Image):
    for tag in img.Tags:
        print(f"  Image tag: label={tag.label!r}  completed={tag.completed}")

Gambar per halaman

from aspose.note import Document, Page, Image

doc = Document("MyNotes.one")
for page_num, page in enumerate(doc.GetChildNodes(Page), start=1):
    images = page.GetChildNodes(Image)
    print(f"Page {page_num}: {len(images)} image(s)")

Keamanan None

FileName adalah None ketika tidak ada nama file yang disimpan: selalu sediakan fallback saat menulis ke disk.
Bytes selalu merupakan bytes objek dan tidak pernah None.
Width dan Height adalah None untuk gambar tanpa metadata dimensi.
AlternativeTextTitle, AlternativeTextDescription, dan HyperlinkUrl adalah None ketika tidak diatur.
