# PointUtils

> Conversion utilities between the EMR coordinate system and screen pixel coordinates.

`PointUtils` converts between two coordinate systems:

* **Pixel coordinate system**: screen rendering/layout coordinates (unit: px)
* **EMR coordinate system**: digitizer/handwriting hardware coordinates (unit: hardware units)

For background and differences between the two coordinate systems, see: [Coordinate System](/en/plugin-base/coordinate-system).

```ts theme={null}
import { PointUtils } from 'sn-plugin-lib';
```
