#鸿蒙通关秘籍#自定义绘制图像，在ArkTS卡片中怎么实现？因为我看见，有一些能力在元服务不能用

@Entry@Component
struct CustomCanvasDrawingCard {
    private canvasWidth: number = 0;
    private canvasHeight: number = 0;
    private settings: RenderingContextSettings = new RenderingContextSettings(true);
    private context: CanvasRenderingContext2D = new CanvasRenderingContext2D(this.settings);

    build() {
        Column() {
            Row() {
                Canvas(this.context)
                .width('100%')
                .height('100%')
                .onReady(() => {
                    // 绘制代码
                });
            }
        }
    }
}
