title: "BlurredEdgeTreatment"
description: "Determines the strategy used to render pixels in the blurred result that may extend beyond the
bounds of the original input.

[BlurredEdgeTreatment] will clip the blur result to the boundaries of the original content and
optionally specified [shape].

Sampling of pixels outside of content bounds will have the same value as the pixels at the
closest edge. This is recommended for blurring content that does not contain transparent pixels
and ensuring the blurred result does not extend beyond the original bounds (ex. blurring an
image)


Alternatively using [BlurredEdgeTreatment.Unbounded] will not clip the blur result to the
boundaries of the original content. Sampling of pixels outside of the content bounds will sample
transparent black instead. This is recommended for blurring content that is intended to render
outside of the original bounds and may contain transparent pixels in the original bounds (ex.
blurring an arbitrary shape or text)"

Determines the strategy used to render pixels in the blurred result that may extend beyond the
bounds of the original input.

`BlurredEdgeTreatment` will clip the blur result to the boundaries of the original content and
optionally specified `shape`.

Sampling of pixels outside of content bounds will have the same value as the pixels at the
closest edge. This is recommended for blurring content that does not contain transparent pixels
and ensuring the blurred result does not extend beyond the original bounds (ex. blurring an
image)


Alternatively using `BlurredEdgeTreatment.Unbounded` will not clip the blur result to the
boundaries of the original content. Sampling of pixels outside of the content bounds will sample
transparent black instead. This is recommended for blurring content that is intended to render
outside of the original bounds and may contain transparent pixels in the original bounds (ex.
blurring an arbitrary shape or text)

```kotlin
val Rectangle = BlurredEdgeTreatment(RectangleShape)

Bounded `BlurredEdgeTreatment` that clips content bounds to a rectangular shape

```kotlin
val Unbounded = BlurredEdgeTreatment(null)
```


Do not clip the blur result to the boundaries of the original content. Sampling of pixels
outside of the content bounds will sample transparent black instead. This is recommended
for blurring content that is intended to render outside of the original bounds and may
contain transparent pixels in the original bounds (ex. blurring an arbitrary shape or
text)
