# 🗒️ Aspose.Note for Python (Aspose-compatible API)

Quick links: [📚 Examples](examples/) • [📦 PyPI](https://pypi.org/project/aspose-note/)

✅ **Official Aspose project** — **100% free & open-source (Split License; see https://www.aspose.org/)**. Provides an Aspose.Note-compatible Python API for working with OneNote `.one` files.

This repository provides a Python library with an **Aspose.Note-shaped public API** for reading Microsoft OneNote files (`.one`).

The goal is to offer a familiar surface (`aspose.note.*`) inspired by [Aspose.Note for .NET](https://products.aspose.com/note/net/), backed by this repository’s built-in MS-ONE/OneStore parser.

## ✨ Features

- ✅ Read `.one` from a file path or a binary stream
- ✅ Aspose-like DOM (Document/Page/Outline/…): traversal + type-based search
- ✅ Content extraction
  - ✅ Rich text with formatting runs (TextRun/TextStyle) and hyperlinks
  - ✅ Images (bytes, file name, dimensions)
  - ✅ Attached files (bytes, file name)
  - ✅ Tables (rows/cells + cell content)
  - ✅ OneNote tags (NoteTag) on text/images/tables/list elements
  - ✅ Numbered lists (NumberList) and indent levels
- ✅ PDF export via `Document.Save(..., SaveFormat.Pdf)` (uses ReportLab)

## 🚀 Quick start

```python
from aspose.note import Document

doc = Document("testfiles/SimpleTable.one")
print(doc.DisplayName)
print(doc.Count())

# pages are direct children of Document
for page in doc:
    print(page.Title.TitleText.Text)
```

### 📄 Export to PDF

```python
from aspose.note import Document, SaveFormat

doc = Document("testfiles/FormattedRichText.one")
doc.Save("out.pdf", SaveFormat.Pdf)
```

## 📦 Installation

From PyPI:

```bash
python -m pip install aspose-note
```

With PDF export support:

```bash
python -m pip install "aspose-note[pdf]"
```

From a local checkout:

```bash
python -m pip install -e .
```

PDF export requires ReportLab:

```bash
python -m pip install -e ".[pdf]"
```

PyPI release page (maintainers): https://pypi.org/manage/project/aspose-note/releases/

## 🧩 Public API (what is considered supported)

Only the `aspose.note` package is considered **public and supported**.
Everything under `aspose.note._internal` is internal implementation detail and may change.

### 📝 Extract all text from an MS OneNote document

```python
from aspose.note import Document, RichText

doc = Document("testfiles/FormattedRichText.one")
texts = [rt.Text for rt in doc.GetChildNodes(RichText)]
print("\n".join(texts))
```

### 🖼️ Save all images from an MS OneNote document to disk

```python
from aspose.note import Document, Image

doc = Document("testfiles/3ImagesWithDifferentAlignment.one")
for i, img in enumerate(doc.GetChildNodes(Image), start=1):
    name = img.FileName or f"image_{i}.bin"
    with open(name, "wb") as f:
        f.write(img.Bytes)
```

### 🏷️📄 Export an MS OneNote document to PDF (custom tag icons)

```python
from aspose.note import Document, PdfSaveOptions, SaveFormat

doc = Document("testfiles/TagSizes.one")
opts = PdfSaveOptions(
    SaveFormat=SaveFormat.Pdf,
    TagIconDir="./tag-icons",
    TagIconSize=10,
    TagIconGap=2,
)
doc.Save("out.pdf", opts)
```

### 📦 Load an MS OneNote document from a binary stream

```python
from pathlib import Path
from aspose.note import Document

one_path = Path("testfiles/SimpleTable.one")
with one_path.open("rb") as f:
  doc = Document(f)

print(doc.DisplayName)
print(doc.Count())
```

### 🧭 Traverse MS OneNote document structure (DOM) and print a simple outline

```python
from aspose.note import Document, Page, Outline, OutlineElement, RichText

doc = Document("testfiles/SimpleTable.one")

for page in doc.GetChildNodes(Page):
  title = page.Title.TitleText.Text if page.Title and page.Title.TitleText else "(no title)"
  print(f"# {title}")

  for outline in page.GetChildNodes(Outline):
    for oe in outline.GetChildNodes(OutlineElement):
      # OutlineElement may contain RichText, Table, Image, etc.
      texts = [rt.Text for rt in oe.GetChildNodes(RichText)]
      if texts:
        print("-", " ".join(t.strip() for t in texts if t.strip()))
```

### 🔎 Count MS OneNote DOM nodes with `DocumentVisitor`

```python
from aspose.note import Document, DocumentVisitor, Page, Image, RichText


class Counter(DocumentVisitor):
  def __init__(self) -> None:
    self.pages = 0
    self.rich_texts = 0
    self.images = 0

  def VisitPageStart(self, page: Page) -> None:  # noqa: N802
    self.pages += 1

  def VisitRichTextStart(self, rich_text: RichText) -> None:  # noqa: N802
    self.rich_texts += 1

  def VisitImageStart(self, image: Image) -> None:  # noqa: N802
    self.images += 1


doc = Document("testfiles/3ImagesWithDifferentAlignment.one")
counter = Counter()
doc.Accept(counter)
print(counter.pages, counter.rich_texts, counter.images)
```

### 🔗 Extract hyperlinks from formatted text in an MS OneNote document

```python
from aspose.note import Document, RichText

doc = Document("testfiles/FormattedRichText.one")
for rt in doc.GetChildNodes(RichText):
  for run in rt.Runs:
    if run.Style.IsHyperlink and run.Style.HyperlinkAddress:
      print(run.Text, "->", run.Style.HyperlinkAddress)
```

### 🏷️ Inspect MS OneNote tags (NoteTag) across the document

```python
from aspose.note import Document, RichText, Image, Table

doc = Document("testfiles/TagSizes.one")

def dump_tags(kind: str, tags) -> None:
  for t in tags:
    print(kind, "tag:", t.label)

for rt in doc.GetChildNodes(RichText):
  dump_tags("RichText", rt.Tags)

for img in doc.GetChildNodes(Image):
  dump_tags("Image", img.Tags)

for tbl in doc.GetChildNodes(Table):
  dump_tags("Table", tbl.Tags)
```

### 🧱 Work with tables in an MS OneNote document (rows/cells)

```python
from aspose.note import Document, Table, TableRow, TableCell, RichText

doc = Document("testfiles/SimpleTable.one")

for table in doc.GetChildNodes(Table):
  print("Table columns:", table.ColumnWidths)
  for row_index, row in enumerate(table.GetChildNodes(TableRow), start=1):
    cells = row.GetChildNodes(TableCell)
    values: list[str] = []
    for cell in cells:
      cell_text = " ".join(rt.Text for rt in cell.GetChildNodes(RichText)).strip()
      values.append(cell_text)
    print(f"Row {row_index}:", values)
```

### 📎 Extract attached files from an MS OneNote document

```python
from aspose.note import Document, AttachedFile

doc = Document("testfiles/OnePageWithFile.one")

for i, af in enumerate(doc.GetChildNodes(AttachedFile), start=1):
  name = af.FileName or f"attachment_{i}.bin"
  with open(name, "wb") as f:
    f.write(af.Bytes)
  print("saved:", name)
```

### 🔢 Inspect numbered lists in an MS OneNote document (NumberList + indentation)

```python
from aspose.note import Document, OutlineElement

doc = Document("testfiles/NumberedListWithTags.one")

for oe in doc.GetChildNodes(OutlineElement):
  nl = oe.NumberList
  if nl is None:
    continue
  print(
    "indent=", oe.IndentLevel,
    "is_numbered=", nl.IsNumbered,
    "format=", nl.Format,
    "restart=", nl.Restart,
  )
```

## ⚠️ Current limitations

- The implementation focuses on **reading** `.one` and building a DOM; writing back to `.one` is not implemented.
- `DocumentPassword` / encrypted documents are not supported (raises `IncorrectPasswordException`).
- Saving formats other than PDF (HTML/images/ONE) are declared for compatibility but not implemented.
