隨着冬奧會的開展，冰墩墩風靡一時，本着好奇之心及對冰墩墩的喜愛，本文采用WPF繪制冰墩墩，僅供學習分享使用，如有不足之處，還請指正。
什么是冰墩墩？
冰墩墩（英文：Bing Dwen Dwen，漢語拼音：bīng dūn dūn），是2022年北京冬季奧運會的吉祥物。 將熊貓形象與富有超能量的冰晶外殼相結合，頭部外殼造型取自冰雪運動頭盔，裝飾彩色光環，整體形象酷似航天員。
涉及知識點
通過分析冰墩墩圖形，對其進行拆解，並結合WPF繪圖基礎知識，涉及知識點如下所示：
- Canvas畫布基礎實時，主要是布局定位。
- 基礎圖形Rectangle(矩形)，Eclipse(橢圓)，Path(路徑)的繪制。
- 圖形變換，如：TranslateTransform（移動），RotateTransform（旋轉），ScaleTransform（縮放）等基礎知識
示例效果圖
示例效果可能和真實圖片略有差異，具體效果圖如下所示：
核心代碼
本示例主要由WPF的XAML完成，如下所示：
