Android ImageBitmap 使用 GlideCoil 到画布

您不需要ImageBitmap将其绘制到画布中.你可以在DrawScope里面画画师.您甚至实际上也不需要画布函数.androidx.compose.foundation.Canvas不是别的，就是空格和Modifier.drawBehind

@Composable
fun Canvas(modifier: Modifier, onDraw: DrawScope.() -> Unit) =
    Spacer(modifier.drawBehind(onDraw))

对你的问题的回答是

@Composable
private fun MyComposable() {
    val sizeModifier = Modifier
        .fillMaxWidth()

    val url =
        "https://avatars3.githubusercontent.com/u/35650605?s=400&u=058086fd5c263f50f2fbe98ed24b5fbb7d437a4e&v=4"

    Column(
        modifier =Modifier.fillMaxSize()
    ) {

      val painter =  rememberAsyncImagePainter(
            model = url
        )

        Canvas(modifier = Modifier
            .clip(RoundedCornerShape(size = 16.dp))
                .size(220.dp)
            ) {
                with(painter) {
                    draw(size = size)
                }
            }

    }
}

当您应用Modifier.lip()时，您不必应用Modifier.clipToBound()

这两种用法与Clip对Clip ToBound使用额外形状是一样的

/**
 * Clip the content to the bounds of a layer defined at this modifier.
 */
@Stable
fun Modifier.clipToBounds() = graphicsLayer(clip = true)

/**
 * Clip the content to [shape].
 *
 * @param shape the content will be clipped to this [Shape].
 */
@Stable
fun Modifier.clip(shape: Shape) = graphicsLayer(shape = shape, clip = true)
