CropImageParams Class

@Immutable data class CropImageParams(val cropGrip: Painter, val cropHalo: Painter, val edgeGrip: Painter, val edgeHalo: Painter, val normalLineColor: Color, val normalLineStyle: DrawStyle, val invalidLineColor: Color, val invalidLineStyle: DrawStyle, val zoomImageParams: ZoomImageParams, val blurRadius: Dp)

How the crop surface looks and behaves: handle size, stroke widths, and colours.

The outline is drawn in the normal colour and style while the four corners form a valid quadrilateral, and in the invalid pair as soon as they do not — dragging one corner past another, for instance. The same colour tints the grip images, so the whole surface changes together.

Parameters

cropGrip — the image drawn at each corner the user can drag.
cropHalo — the image drawn behind a corner grip to show its touch area.
edgeGrip — the image drawn at the midpoint of each edge.
edgeHalo — the image drawn behind an edge grip to show its touch area.
normalLineColor — the outline colour while the corners form a valid shape.
normalLineStyle — the stroke used for that outline.
invalidLineColor — the outline colour once the corners no longer form a valid shape.
invalidLineStyle — the stroke used for that outline; dashed by default, so the state reads without relying on colour alone.
zoomImageParams — how the page behind the crop surface zooms and pans.
blurRadius — how strongly the area outside the crop is blurred. Set it to 0.dp to leave the page unblurred; the effect also needs Android 12, and is skipped below it.
