如何繪制動畫效果填充SVG？

Question

我正在嘗試為 SVG 徽標設置動畫，例如在沒有筆划的情況下繪制填充路徑。 我的標志看起來像那樣。

是否可以創建填充圖而不是筆划？ 我看到了很多關於這個的解決方案，但都被筆畫使用了。 我還發現此解決方案與我的問題非常相似。 但是我的 SVG 路徑有點復雜，無法創建類似於他們創建的筆划的假路徑。 我希望它從無到有，並用填充繪制動畫效果。

Answer 1

你的人物是用雙筆畫畫的

因此，不可能使用stroke-dasharray為其填充顏色設置動畫
考慮創建一個在形狀中間延伸的輪廓。

將這條線的寬度設置為25px ，我們將通過更改stroke-dasharray的屬性來為其外觀設置動畫

動畫 CSS

 .container { padding:10px; background-color:#151515; width:50%; } .draw-logo { fill:none; stroke:#F7F7F7; stroke-width:25; stroke-dasharray:0,425; animation: draw 4s linear forwards; animation-iteration-count: 2; } @keyframes draw { 0% {stroke-dasharray: 0,425;} 100% {stroke-dasharray: 425,0;} }

Answer 2

因為您的 SVG 文件與我的徽標形狀不同。 你能告訴我如何修改路徑以獲得完全相同的形狀。 順便說一下，我對插畫家的了解不多。

不幸的是，我不使用插圖畫家。 在Inkscape 中繪制的路徑

打開上一個答案中的文件以在Inkscape編輯path表單

1. 在工具欄上的矢量編輯器中選擇Edit contour nodes F2 （箭頭紅色-1）

2. 通過拖動節點來編輯曲線的形狀並改變節點控制桿的長度和位置（箭頭紅色-2）

3. 矢量編輯器節省了大量開銷信息。 要刪除它，您需要使用SVG Editor優化保存的文件

4. 用優化文件中的新path替換舊path
