Name: python-xbrz.py
Version: 1.0.2
Release: 1
Summary: ctypes-based binding library for the xBRZ pixel-art image scaling algorithm
License: AGPL-3.0-or-later
URL: https://github.com/iomintz/xbrz.py
Source0: https://mirrors.nju.edu.cn/pypi/web/packages/a7/47/b2718f5151454f0ccfb8b77ca2b1aacac1d6319fa7bbee6f22ccb1d0cfdb/xbrz.py-1.0.2.tar.gz
Requires: python3-Pillow
Requires: python3-Wand
%description
# xbrz.py
[](https://travis-ci.org/iomintz/xbrz.py)
xbrz.py is a simple ctypes-based binding library for [xBRZ], a high-quality pixel-art image scaling algorithm.
## Installation
Wheels are available for many platforms. If there isn't one for your platform, make sure you have a C++ compiler handy.
```
pip install xbrz.py
```
## Usage
```py
import xbrz
# pixels is a list of 32 bit ints representing RGBA colors.
# It is 32 * 24 long.
pixels = ...
scaled_pixels = xbrz.scale(pixels, 6, 32, 24, xbrz.ColorFormat.RGBA)
# scaled_pixels is a 32 * 24 * 6 ** 2 long list of 32 bit ints representing the scaled image.
```
## Wand / Pillow support
You can pass a Wand image to `xbrz.scale_wand(img, factor)` or a Pillow image to `xbrz.scale_pillow(img, factor)`.
Neither libraries are required to use xbrz.py, however they can be installed via:
```
pip install xbrz.py[wand]
# or
pip install xbrz.py[pillow]
```
## xbrz.py as an executable module
Passing raw RGBA pixels to `python3 -m xbrz <factor> <width> <height>`
via stdin will output scaled raw RGBA pixels to stdout.
## License
AGPLv3, see LICENSE.md. The original xBRZ code is GPLv3 licensed.
- lib/ is based on code provided by Zenju under the GPLv3 license. See lib/License.txt for details.
Some changes were made:
- Added some `extern "C"` declarations to the functions I intended to call from python.
- Removed some namespace use to avoid being mangled.
- Replaced a C++ template with a simple function that takes two arguments.
- Converted the library to use RGBA instead of ARGB.
- xbrz.py is based on lib/ and is released under the AGPLv3 license, see LICENSE.md for details.
