interface DrawTransform

androidx.compose.ui.graphics.drawscope.DrawTransform

Defines transformations that can be applied to a drawing environment

Summary

Public methods
abstract Unit	`clipPath(path: Path, clipOp: ClipOp = ClipOp.Intersect)` Reduces the clip region to the intersection of the current clip and the given rounded rectangle.
abstract Unit	`clipRect(left: Float = 0.0f, top: Float = 0.0f, right: Float = size.width, bottom: Float = size.height, clipOp: ClipOp = ClipOp.Intersect)` Reduces the clip region to the intersection of the current clip and the given rectangle indicated by the given left, top, right and bottom bounds.
abstract Unit	`inset(left: Float, top: Float, right: Float, bottom: Float)` Simultaneously translate the coordinate space by left and top as well as modify the dimensions of the current painting area.
abstract Unit	`rotate(degrees: Float, pivot: Offset = center)` Add a rotation (in degrees clockwise) to the current transform at the given pivot point.
abstract Unit	`scale(scaleX: Float, scaleY: Float, pivot: Offset = center)` Add an axis-aligned scale to the current transform, scaling by the first argument in the horizontal direction and the second in the vertical direction at the given pivot coordinate.
abstract Unit	`transform(matrix: Matrix)` Transform the drawing environment by the given matrix
abstract Unit	`translate(left: Float = 0.0f, top: Float = 0.0f)` Translate the coordinate space by the given delta in pixels in both the x and y coordinates respectively

Extension functions

From androidx.compose.ui.graphics.drawscope

Unit	`DrawTransform.inset(horizontal: Float = 0.0f, vertical: Float = 0.0f)` Convenience method modifies the DrawTransform bounds to inset both left and right bounds by horizontal as well as the top and bottom by vertical.
Unit	`DrawTransform.inset(inset: Float)` Convenience method modifies the DrawScope bounds to inset both left, top, right and bottom bounds by inset.
Unit	`DrawTransform.rotateRad(radians: Float, pivot: Offset = center)` Add a rotation (in radians clockwise) to the current transform at the given pivot point.
Unit	`DrawTransform.scale(scale: Float, pivot: Offset = center)` Add an axis-aligned scale to the current transform, scaling uniformly in both directions by the provided scale factor at the pivot coordinate.

Properties
open Offset	`center` Convenience method to obtain the current position of the current transformation
abstract Size	`size` Get the current size of the CanvasTransform

Public methods

clipPath

abstract fun clipPath(
    path: Path, 
    clipOp: ClipOp = ClipOp.Intersect
): Unit

Reduces the clip region to the intersection of the current clip and the given rounded rectangle. After this method is invoked, this clip is no longer applied

Parameters
path: Path	Shape to clip drawing content within
clipOp: ClipOp = ClipOp.Intersect	Clipping operation to conduct on the given bounds, defaults to ClipOp.Intersect

clipRect

abstract fun clipRect(
    left: Float = 0.0f, 
    top: Float = 0.0f,
