原文:WPF筆記(1.10 繪圖)——Hello，WPF！

書中的代碼文法過時了，改寫為以下(測試通過)：

        <Button>
            <Button.LayoutTransform>
                <ScaleTransform  ScaleX="3" ScaleY="3" />
            </Button.LayoutTransform>
            <StackPanel Orientation="Horizontal">
                <Canvas Width="20" Height="18" VerticalAlignment="Center">
                    <Ellipse Canvas.Left="1" Canvas.Top="1" Width="16" Height="16"
                      Fill="Yellow" Stroke="Black" />
                    <Ellipse Canvas.Left="4.5" Canvas.Top="5" Width="2.5" Height="3"
                      Fill="Black" />
                    <Ellipse Canvas.Left="11" Canvas.Top="5" Width="2.5" Height="3"
                      Fill="Black" />
                    <Path Data="M 5,10 A 3,3 0 0 0 13,10" Stroke="Blue" />
                </Canvas>
                <TextBlock VerticalAlignment="Center">Click!</TextBlock>
            </StackPanel>
        </Button>
ScaleTransform將button放大3倍。
Canvas上畫圖，畫一個笑臉，3個橢圓，黃色是臉的輪廓，黃色是眼睛。藍色鋼筆畫的是嘴巴——可以順便瞭解這四個元素在Canvas上是怎麼精確定位的。
