hqx (high quality scale) is a family of pixel art scaling algorithms that work by detecting differences between pixels in the YUV colorspace.
hq2x scales an image by 2x, hq3x by 3x, and hq4x by 4x.
This is a Python port of hqx, unoptimized. It is not intended to be used for videos or scenarios where low latency is required. Right now, it only supports RGB, not RGBA (no transparency support).

📦 Installation
hqx is available on PyPi.
It requires a Python version of at least 3.10.0.
It depends on Pillow.
To install hqx with pip, run:
python -m pip install hqx
🛠 Usage
You can either use hqx.hqx_scale, hqx.hq2x, hqx.hq3x, or hqx.hq4x.
import hqx
import PIL.Image
image: PIL.Image.Image = PIL.Image.open(...)
x2: PIL.Image.Image = hqx.hq2x(image)
x3: PIL.Image.Image = hqx.hq3x(image)
x4: PIL.Image.Image = hqx.hq4x(image)
# x2 == hqx.hqx_scale(image, 2))
# x3 == hqx.hqx_scale(image, 3))
# x4 == hqx.hqx_scale(image, 4))
