```kotlin
inline fun DrawScope.withTransform(
    transformBlock: DrawTransform.() -> Unit,
    drawBlock: DrawScope.() -> Unit,
) =
    with(drawContext) {
        val previousSize = size
        canvas.save()
        try {
            transformBlock(transform)
            drawBlock()
        } finally {
            canvas.restore()
            size = previousSize
        }
    }
```


Perform 1 or more transformations and execute drawing commands with the specified transformations
applied. After this call is complete, the transformation before this call was made is restored

#### Parameters

| | |
| --- | --- |
| transformBlock | Callback invoked to issue transformations to be made before the drawing operations are issued |
| drawBlock | Callback invoked to issue drawing operations after the transformations are applied |




## Code Examples
### DrawScopeBatchedTransformSample
```kotlin
@Composable
fun DrawScopeBatchedTransformSample() {
    Canvas(Modifier.size(120.dp)) { // CanvasScope
        inset(20.0f) {
            // Use withTransform to batch multiple transformations for 1 or more drawing calls
            // that are to be drawn.
            // This is more efficient than issuing nested translation, rotation and scaling
            // calls as the internal state is saved once before and after instead of multiple
            // times between each transformation if done individually
            withTransform({
                translate(10.0f, 12.0f)
                rotate(45.0f, center)
                scale(2.0f, 0.5f)
            }) {
                drawRect(Color.Cyan)
                drawCircle(Color.Blue)
            }
            drawRect(Color.Red, alpha = 0.25f)
        }
    }
}
```
