## Description

Downsampling resolution for raster images. The plugin supports only this discrete set; arbitrary DPI values are not accepted. Numeric values match the underlying `WebToPDFDownsamplingDPI` enum so a `static_cast` suffices at the bridge.

## Values

- `Disabled = -1`: Preserve original resolution.
- `DPI300 = 0`: 300 DPI (plugin default)
- `DPI75 = 1`: 75 DPI (screen quality)
- `DPI150 = 2`: 150 DPI
- `DPI600 = 3`: 600 DPI (high quality print)
- `DPI1200 = 4`: 1200 DPI (very high quality)
