## Demos
### DemoContours01
Demonstrates how to convert a PNG image into `ShapeContour`s using BoofCV.
Two helper methods help convert data types between BoofCV and OPENRNDR.
The `ColorBuffer.toGrayF32()` method converts an OPENRNDR `ColorBuffer` to `GrayF32` format,
required by BoofCV.
The `.toShapeContours()` converts BoofCV contours to OPENRNDR `ShapeContour` instances.
The resulting contours are animated zooming in and out while their colors change slowly.

Demonstrates how to scale down images using the `resizeTo` BoofCV-based

If only the `newWidth` or the `newHeight` arguments are specified,
the resizing happens maintaining the original aspect ratio.

### DemoSimplified01
When converting a `ColorBuffer` to `ShapeContour` instances using
`BoofCV`, simple shapes can have hundreds of segments and vertices.
This demo shows how to use the `simplify()` method to greatly
reduce the number of vertices.
Then it uses the simplified vertex lists to create smooth curves
(using `CatmullRomChain2`) and polygonal curves (using `ShapeContour.fromPoints`).
Study the console to learn about the number of segments before and after simplification.
