+# Background
+
+The background plugin is used to customize canvas background effects, supporting dot patterns, logo display, and neumorphism visual effects.
+
+## Background Configuration
+
+The background plugin is provided through `BackgroundPlugin`, configuration options include:
+
+### Basic Configuration
+
+<img loading="lazy" className="invert-img" src="/free-layout/background-color.png"/>
+
+```ts pure
+{
+  // Background color
+  backgroundColor: '#1a1a1a',
+
+  // Dot color
+  dotColor: '#ffffff',
+
+  // Dot size (pixels)
+  dotSize: 1,
+
+  // Grid spacing (pixels)
+  gridSize: 20,
+
+  // Dot opacity (0-1)
+  dotOpacity: 0.5,
+
+  // Dot fill color
+  dotFillColor: '#ffffff'
+}
+```
+
+### Logo Configuration
+
+Supports both text and image logo types:
+
+<img loading="lazy" className="invert-img" src="/free-layout/background-logo.png"/>
+
+```ts pure
+{
+  logo: {
+    // Logo text
+    text: 'FLOWGRAM.AI',
+
+    // Image URL (optional, higher priority than text)
+    imageUrl: 'https://example.com/logo.png',
+
+    // Position: 'center' | 'top-left' | 'top-right' | 'bottom-left' | 'bottom-right'
+    position: 'center',
+
+    // Size
+    size: 200,
+
+    // Opacity (0-1)
+    opacity: 0.25,
+
+    // Color
+    color: '#ffffff',
+
+    // Font family
+    fontFamily: 'Arial, sans-serif',
+
+    // Font weight
+    fontWeight: 'bold',
+
+    // Custom offset
+    offset: { x: 0, y: 0 }
+  }
+}
+```
+
+### Neumorphism Effect
+
+Neumorphism is a modern visual design style that creates depth through dual soft shadows:
+
+<img loading="lazy" className="invert-img" src="/free-layout/background-neumorphism.png"/>
+
+```ts pure
+{
+  logo: {
+    neumorphism: {
+      // Enable neumorphism effect
+      enabled: true,
+
+      // Text color
+      textColor: '#E0E0E0',
+
+      // Light shadow color
+      lightShadowColor: 'rgba(255,255,255,0.9)',
+
+      // Dark shadow color
+      darkShadowColor: 'rgba(0,0,0,0.15)',
+
+      // Shadow offset distance
+      shadowOffset: 6,
+
+      // Shadow blur radius
+      shadowBlur: 12,
+
+      // Shadow intensity
+      intensity: 0.6,
+
+      // Raised effect (true=raised, false=inset)
+      raised: true
+    }
+  }
+}
+```
+
+## Usage Example
+
+```tsx pure
+// Use background property directly in editor configuration
+const editorProps = {
+  // Background configuration
+  background: {
+    // Dark theme background
+    backgroundColor: '#1a1a1a',
+    dotColor: '#ffffff',
+    dotSize: 1,
+    gridSize: 20,
+    dotOpacity: 0.3,
+
+    // Brand logo
+    logo: {
+      text: 'FLOWGRAM.AI',
+      position: 'center',
+      size: 200,
+      opacity: 0.25,
+      color: '#ffffff',
+      fontFamily: 'Arial, sans-serif',
+      fontWeight: 'bold',
+
+      // Neumorphism effect
+      neumorphism: {
+        enabled: true,
+        textColor: '#E0E0E0',
+        lightShadowColor: 'rgba(255,255,255,0.9)',
+        darkShadowColor: 'rgba(0,0,0,0.15)',
+        shadowOffset: 6,
+        shadowBlur: 12,
+        intensity: 0.6,
+        raised: true
+      }
+    }
+  }
+}
+```
+
+## Preset Styles
+
+### Classic Dark Theme
+
+```tsx pure
+const editorProps = {
+  background: {
+    backgroundColor: '#1a1a1a',
+    dotColor: '#ffffff',
+    dotSize: 1,
+    gridSize: 20,
+    dotOpacity: 0.3,
+    logo: {
+      text: 'Your Brand',
+      position: 'center',
+      size: 200,
+      opacity: 0.25,
+      color: '#ffffff',
+      neumorphism: {
+        enabled: true,
+        textColor: '#E0E0E0',
+        lightShadowColor: 'rgba(255,255,255,0.9)',
+        darkShadowColor: 'rgba(0,0,0,0.15)',
+        shadowOffset: 6,
+        shadowBlur: 12,
+        intensity: 0.6,
+        raised: true
+      }
+    }
+  }
+}
+```
+
+### Minimal White Theme
+
+```tsx pure
+const editorProps = {
+  background: {
+    backgroundColor: '#ffffff',
+    dotColor: '#000000',
+    dotSize: 1,
+    gridSize: 20,
+    dotOpacity: 0.1,
+    logo: {
+      text: 'Your Brand',
+      position: 'center',
+      size: 200,
+      opacity: 0.1,
+      color: '#000000'
+    }
+  }
+}
+```
+
+## Notes
+
+1. **Color Matching**: Ensure sufficient contrast between logo color and background color
+2. **Opacity Settings**: Logo opacity should not be too high to avoid affecting content readability
+3. **Neumorphism Effect**: Shadow parameters should be adjusted reasonably, overly strong effects may distract attention
+4. **Performance Considerations**: Complex shadow effects may impact rendering performance, consider simplifying on low-end devices
+

+# 背景
+
+背景插件用于自定义画布的背景效果，支持点阵背景、Logo显示和新拟态(Neumorphism)视觉效果。
+
+## 背景配置
+
+背景插件通过 `BackgroundPlugin` 提供，配置项包括：
+
+### 基础配置
+
+<img loading="lazy" className="invert-img" src="/free-layout/background-color.png"/>
+
+```ts pure
+{
+  // 背景颜色
+  backgroundColor: '#1a1a1a',
+
+  // 点的颜色
+  dotColor: '#ffffff',
+
+  // 点的大小(像素)
+  dotSize: 1,
+
+  // 网格间距(像素)
+  gridSize: 20,
+
+  // 点的透明度(0-1)
+  dotOpacity: 0.5,
+
+  // 点的填充颜色
+  dotFillColor: '#ffffff'
+}
+```
+
+### Logo配置
+
+支持文本和图片两种Logo类型：
+
+<img loading="lazy" className="invert-img" src="/free-layout/background-logo.png"/>
+
+```ts pure
+{
+  logo: {
+    // Logo文本
+    text: 'FLOWGRAM.AI',
+
+    // 图片URL (可选，优先级高于文本)
+    imageUrl: 'https://example.com/logo.png',
+
+    // 位置：'center' | 'top-left' | 'top-right' | 'bottom-left' | 'bottom-right'
+    position: 'center',
+
+    // 大小
+    size: 200,
+
+    // 透明度(0-1)
+    opacity: 0.25,
+
+    // 颜色
+    color: '#ffffff',
+
+    // 字体
+    fontFamily: 'Arial, sans-serif',
+
+    // 字体粗细
+    fontWeight: 'bold',
+
+    // 自定义偏移量
+    offset: { x: 0, y: 0 }
+  }
+}
+```
+
+### 新拟态效果
+
+新拟态(Neumorphism)是一种现代化的视觉设计风格，通过双层柔和阴影创造立体感：
+
+<img loading="lazy" className="invert-img" src="/free-layout/background-neumorphism.png"/>
+
+```ts pure
+{
+  logo: {
+    neumorphism: {
+      // 启用新拟态效果
+      enabled: true,
+
+      // 文字颜色
+      textColor: '#E0E0E0',
+
+      // 高光阴影颜色
+      lightShadowColor: 'rgba(255,255,255,0.9)',
+
+      // 暗色阴影颜色
+      darkShadowColor: 'rgba(0,0,0,0.15)',
+
+      // 阴影偏移距离
+      shadowOffset: 6,
+
+      // 阴影模糊半径
+      shadowBlur: 12,
+
+      // 阴影强度
+      intensity: 0.6,
+
+      // 凸起效果(true=凸起, false=凹陷)
+      raised: true
+    }
+  }
+}
+```
+
+## 使用示例
+
+```tsx pure
+// 在编辑器配置中直接使用 background 属性
+const editorProps = {
+  // 背景配置
+  background: {
+    // 深色主题背景
+    backgroundColor: '#1a1a1a',
+    dotColor: '#ffffff',
+    dotSize: 1,
+    gridSize: 20,
+    dotOpacity: 0.3,
+
+    // 品牌Logo
+    logo: {
+      text: 'FLOWGRAM.AI',
+      position: 'center',
+      size: 200,
+      opacity: 0.25,
+      color: '#ffffff',
+      fontFamily: 'Arial, sans-serif',
+      fontWeight: 'bold',
+
+      // 新拟态效果
+      neumorphism: {
+        enabled: true,
+        textColor: '#E0E0E0',
+        lightShadowColor: 'rgba(255,255,255,0.9)',
+        darkShadowColor: 'rgba(0,0,0,0.15)',
+        shadowOffset: 6,
+        shadowBlur: 12,
+        intensity: 0.6,
+        raised: true
+      }
+    }
+  }
+}
+```
+
+## 预设样式
+
+### 经典黑色主题
+
+```tsx pure
+const editorProps = {
+  background: {
+    backgroundColor: '#1a1a1a',
+    dotColor: '#ffffff',
+    dotSize: 1,
+    gridSize: 20,
+    dotOpacity: 0.3,
+    logo: {
+      text: '您的品牌',
+      position: 'center',
+      size: 200,
+      opacity: 0.25,
+      color: '#ffffff',
+      neumorphism: {
+        enabled: true,
+        textColor: '#E0E0E0',
+        lightShadowColor: 'rgba(255,255,255,0.9)',
+        darkShadowColor: 'rgba(0,0,0,0.15)',
+        shadowOffset: 6,
+        shadowBlur: 12,
+        intensity: 0.6,
+        raised: true
+      }
+    }
+  }
+}
+```
+
+### 简约白色主题
+
+```tsx pure
+const editorProps = {
+  background: {
+    backgroundColor: '#ffffff',
+    dotColor: '#000000',
+    dotSize: 1,
+    gridSize: 20,
+    dotOpacity: 0.1,
+    logo: {
+      text: '您的品牌',
+      position: 'center',
+      size: 200,
+      opacity: 0.1,
+      color: '#000000'
+    }
+  }
+}
+```
+
+## 注意事项
+
+1. **颜色搭配**：确保Logo颜色与背景色有足够的对比度
+2. **透明度设置**：Logo透明度不宜过高，以免影响内容可读性
+3. **新拟态效果**：需要合理调整阴影参数，过强的效果可能分散注意力
+4. **性能考虑**：复杂的阴影效果可能影响渲染性能，建议在低端设备上适当简化
