Examples
The below examples use the following YAML doc as a file named example-layout.yml.
layers:
- background:
color: "#4051b5"
- icon:
image: material/cat
color: white
offset: { x: 100, y: 100 }
size: { width: 100, height: 100 }
Python
import asyncio # the only supported async runtime in python
from pathlib import Path
# configure loggers before importing this lib
from img_gen import Layout, Generator
async def main():
generator = Generator(
# add any external image/font paths (file or dir) here
external_resource_paths=[],
cache_root=None, # use default cache dir
)
layout = Layout.from_yaml_str(yaml_str)
yaml_str = Path("example-layout.yml").read_text(encoding="utf-8")
# Generator.render() is async
img = await generator.render(layout)
img_hash = img.sha256
img.save(f"{img_hash}.png")
Rust
