To enhance the quality of PDF exports in Superset using WebDriver, you can
adjust the image quality settings by configuring the WebDriver with specific
options. Add the following settings to your `superset_config.py` or
`superset_config_docker.py` file:
```python
WEBDRIVER_OPTION_ARGS = [
"--force-device-scale-factor=2.0",
"--high-dpi-support=2.0",
"--headless",
"--disable-gpu",
"--disable-dev-shm-usage",
"--no-sandbox",
"--disable-setuid-sandbox",
"--disable-extensions"
]
```
The options `--force-device-scale-factor=2.0` and `--high-dpi-support=2.0` are
particularly important for enhancing image quality by increasing the DPI and
scale factor
