# SVG Animation
syui.ai アイコンのホバーアニメーション構築ガイド
## ファイル構成
```
anim/syui.ai.css.svg # アニメーション用SVG
css/svg-animation.css # アニメーション定義CSS
```
## SVG構造
```xml
<svg class="likeButton">
<!-- 爆発エフェクト用の円 -->
<circle class="explosion" r="150" cx="250" cy="250"></circle>
<!-- パーティクル14個の円 -->
<g class="particleLayer">
<circle fill="#ef454aba" cx="130" cy="126.5" r="12.5"/>
<!-- ... 他のパーティクル -->
</g>
<!-- syuiロゴ本体 -->
<g class="icon_syui">
<path class="syui" d="..."/>
</g>
</svg>
```
## 使用方法
### 1. HTMLにCSSを読み込む
```html
<link rel="stylesheet" href="css/svg-animation.css">
```
### 2. SVGをHTMLに埋め込む
```html
<!-- インラインSVG -->
<svg width="77pt" height="77pt" viewBox="0 0 512 512" class="likeButton">
<!-- SVGの内容 -->
</svg>
<!-- または object タグ -->
<object type="image/svg+xml" data="icon/anim/syui.ai.css.svg"></object>
```
## アニメーション要素
### 爆発エフェクトexplosion
ホバー時に中心から広がる円形のストロークアニメーション
```css
@keyframes explosionAnime {
0% { opacity: 0; transform: scale(0.01); }
5% { stroke-width: 200; }
50% { transform: scale(1.1); stroke-width: 1; }
100% { stroke-width: 0; }
}
```
### パーティクルparticleLayer
14個の円がそれぞれ異なる方向に飛び散る
```css
.likeButton:hover .particleLayer circle:nth-child(1) {
animation: particleAnimate1 800ms forwards;
}
```
### ロゴアニメーションsyui
ロゴが縮小→拡大するバウンス効果
```css
@keyframes syuiDeluxeAnime {
40% { transform: scale(1, 0.9) translate(-9%, 9%); }
70% { transform: scale(1.04) translate(-5%, 5%); }
100% { transform: scale(1, 1) translate(0%, 0%); }
}
```
## カスタマイズ
### CSS変数
```css
:root {
--syui-color: #ef454a; /* ロゴの色 */
--particle-color: #ef454aba; /* パーティクルの色 */
--explosion-color: #ef454a; /* 爆発エフェクトの色 */
}
```
### アニメーション時間の変更
```css
.likeButton:hover .explosion {
animation: explosionAnime 1200ms forwards; /* 800ms → 1200ms */
}
```
### パーティクルの移動距離を変更
```css
@keyframes particleAnimate1 {
100% { transform: translate(-32px, -118px); } /* 距離を2倍に */
}
```
## 注意事項
- Pure CSS実装JavaScriptは不要
- `object` タグで読み込む場合、CSSはSVGファイル内または外部参照で適用する必要がある
- インラインSVGの場合、親ドキュメントのCSSがそのまま適用される

# svg
## png to svg conversion (vector trace)
Convert PNG images to true vector SVG using vtracer (Rust):
```bash
# Install vtracer
cargo install vtracer
# Convert PNG to SVG (color mode)
vtracer --input input.png --output output.svg --colormode color
# Convert PNG to SVG (black and white)
vtracer --input input.png --output output.svg
```
**Options:**
- `--colormode color` : Preserve colors (recommended for icons)
- `--colormode binary` : Black and white only
- `--filter_speckle 4` : Remove small artifacts
- `--corner_threshold 60` : Adjust corner detection
**Alternative tools:**
- potrace: `potrace input.pbm -s -o output.svg` (B&W only, requires PBM input)
- Inkscape CLI: `inkscape input.png --export-type=svg` (embeds image, no trace)
**Note:** Inkscape's CLI `--export-type=svg` only embeds the PNG, it does not trace. For true vectorization, use vtracer or potrace.
