# CBZ
CBZ is a Python library designed for creating, manipulating, and viewing comic book files in CBZ, CBR, and PDF formats. It offers a straightforward interface to pack comic pages into CBZ archives, extract metadata from CBZ and CBR files, and display comics using a built-in player.
## Features
- Seamless installation via [pip](#installation)
- Pack images into CBZ format for comics and manga
- Extract and manage metadata: title, series, format, and more
- Handle comic pages with attributes like type, dimensions, and bookmarks
- Unpack CBZ and CBR files to retrieve comic information, or extract images from PDF files
- Built-in player for viewing CBZ, CBR, and PDF comics
- Sequence protocol: iterate, index, and slice comic pages directly
- Dataclass-based models with automatic XML mapping and strict type validation
- Image support: JPEG, PNG, GIF, BMP, TIFF, WebP, JPEG XL, AVIF
- Fully open-source! Pull requests welcome
## Installation
Install CBZ from PyPI using pip:
```shell
pip install cbz
```
With AVIF and JPEG XL support:
```shell
pip install cbz[pillow]
```
## Quick Start
Here's a quick example of how to create a CBZ file from a series of images:
```python
from pathlib import Path
from cbz import ComicInfo, PageInfo, PageType, Format, YesNo, Manga, AgeRating
if __name__ == "__main__":
paths = sorted(Path("path/to/your/images").iterdir())
# Load each page from the images folder into a list of PageInfo objects
pages = [
PageInfo.load(
path=path,
type=(
PageType.FRONT_COVER if i == 0
else PageType.BACK_COVER if i == len(paths) - 1
else PageType.STORY
),
)
for i, path in enumerate(paths)
]
# Create a ComicInfo object with metadata
comic = ComicInfo.from_pages(
pages=pages,
title="Your Comic Title",
series="Your Comic Series",
number=1,
language_iso="en",
format=Format.WEB_COMIC,
black_white=YesNo.NO,
manga=Manga.NO,
age_rating=AgeRating.RATING_PENDING,
)
# Display the comic in the built-in reader
comic.show()
# Save directly as a CBZ file
comic.save("your_comic.cbz")
# Or pack to bytes for custom handling
cbz_content = comic.pack()
Path("your_comic.cbz").write_bytes(cbz_content)
```
## Player
CBZ includes a command-line player for viewing comic book files in multiple formats. Simply run `cbzplayer <file>` to launch the player with the specified comic book file.
### Supported Formats
- **CBZ** (Comic Book ZIP) - Standard ZIP archives containing images and metadata
- **CBR** (Comic Book RAR) - RAR archives containing images and metadata
- **PDF** - Portable Document Format files with embedded images (images only, no metadata)
### Usage
```shell
usage: cbzplayer [-h] <file>
CBZ/CBR/PDF comic reader
positional arguments:
<file> Path to the CBZ, CBR or PDF comic book file.
options:
-h, --help show this help message and exit
```
### Examples
```shell
# View a CBZ file
cbzplayer my_comic.cbz
# View a CBR file
cbzplayer my_comic.cbr
# View a PDF file
cbzplayer my_comic.pdf
```
### Keyboard Shortcuts
| Shortcut | Action |
|---------------------|-------------------|
| Left / Right arrows | Navigate pages |
| + / - | Zoom in / out |
| Ctrl+Q | Quit |
| Mouse wheel | Vertical scroll |
| Shift+Mouse wheel | Horizontal scroll |
| Ctrl+Mouse wheel | Zoom |
### Requirements for CBR Support
CBR file support requires:
- The `rarfile` Python package (automatically installed with CBZ)
- An external RAR extraction tool such as:
- `unrar` (recommended) - Available in most package managers
- `rar` - Commercial RAR archiver
- `7zip` - Free alternative with RAR support
For installation instructions and compatibility details, see the [rarfile documentation](https://github.com/markokr/rarfile).
## Detailed Usage
### Creating a ComicInfo Object
The `ComicInfo` class represents a comic book with metadata and pages. It supports initialization from a list of `PageInfo` objects:
```python
from cbz import ComicInfo, PageInfo, PageType, Format, YesNo, Manga, AgeRating
pages = [
PageInfo.load(path="page1.jpg", type=PageType.FRONT_COVER),
PageInfo.load(path="page2.jpg", type=PageType.STORY),
PageInfo.load(path="page3.jpg", type=PageType.BACK_COVER),
]
comic = ComicInfo.from_pages(
pages=pages,
title="My Comic",
series="Comic Series",
number=1,
language_iso="en",
format=Format.WEB_COMIC,
black_white=YesNo.NO,
manga=Manga.NO,
age_rating=AgeRating.RATING_PENDING,
)
```
You can also create pages directly from bytes or base64-encoded data:
```python
page = PageInfo.loads(data=image_bytes, name="page.jpg", type=PageType.STORY)
```
### Sequence Protocol
`ComicInfo` implements the full sequence protocol, so you can interact with pages directly:
```python
len(comic) # Number of pages
comic[0] # First page
comic[-1] # Last page
comic[1:3] # Slice of pages
for page in comic: # Iteration
print(page.image_width, page.image_height)
page in comic # Containment check
```
### Extracting Metadata
Retrieve comic information as a dictionary using `get_info()`:
```python
info = comic.get_info()
print(info)
```
### Packing and Saving
Pack the comic into CBZ format as bytes:
```python
cbz_content = comic.pack()
```
Or save directly to disk (more memory-efficient for large archives):
```python
comic.save("output.cbz")
```
### Loading from Different Formats
Load a comic from an existing CBZ file (with metadata):
```python
comic = ComicInfo.from_cbz("your_comic.cbz")
```
Load a comic from an existing CBR file (with metadata):
```python
comic = ComicInfo.from_cbr("your_comic.cbr")
```
Load a comic from a PDF file (images only, no metadata):
```python
comic = ComicInfo.from_pdf("your_comic.pdf")
```
**Notes:**
- CBR support requires an external RAR extraction tool. For detailed compatibility information and advanced configuration, see the [rarfile documentation](https://github.com/markokr/rarfile).
- PDF files only provide image content; comic metadata (title, series, etc.) is not available from PDF files.
### Page Properties
Each `PageInfo` object exposes the following properties, automatically extracted from the image content:
```python
page = comic[0]
page.content # bytes - raw image data
page.image_width # int - width in pixels
page.image_height # int - height in pixels
page.image_size # int - file size in bytes
page.suffix # str - file extension (.jpg, .png, etc.)
page.name # str - original file name
page.type # PageType - page type (FrontCover, Story, etc.)
page.bookmark # str - bookmark / chapter name
page.double # bool - double page spread
```
### Metadata Fields
All [ComicInfo.xml](docs/RFC-CBZ.md) v2.1 metadata fields are supported as dataclass attributes:
| Attribute | Type | Default | Description |
