+# 页面 Mixin 重构说明
+
+## 重构目标
+
+将 `mathPageMixin.ts` 改造为通用的页面基类，支持数学学习、专注力等多个模块共用。
+
+## 改造内容
+
+### 1. 创建通用基类
+
+**文件：** `base/pageMixin.ts`
+
+- 提供了通用的页面公共方法
+- 抽象了 `initPageInfo` 方法，支持两种调用方式：
+    1. `initPageInfo(functionId, defaultTitle)` - 可以配合 `pageInfoLookup` 函数使用
+    2. `initPageInfo({ title, desc, functionId })` - 直接提供页面信息
+- 支持通过配置传入模块特定的信息查找函数和分享配置
+
+### 2. 重构数学模块 Mixin
+
+**文件：** `mathPages/common/mathPageMixin.ts`
+
+- 基于通用 `pageMixin` 创建数学模块的包装器
+- 自动配置 `MATH_FUNCTION_TYPES` 查找函数
+- 配置数学模块的分享信息
+- **保持完全向后兼容**，所有现有的数学页面无需修改
+
+### 3. 创建专注力模块示例
+
+**文件：** `focusPages/common/focusPageMixin.ts`
+
+- 展示如何为专注力模块创建专用的 mixin
+- 可以配置 `FOCUS_FUNCTION_TYPES` 查找函数
+- 配置专注力模块的分享信息
+
+## 关键改进
+
+### initPageInfo 方法优化
+
+**之前：**
+
+```typescript
+initPageInfo(functionId: string, defaultTitle?: string) {
+    const functionItem = MATH_FUNCTION_TYPES.find(...); // 硬编码
+    // ...
+}
+```
+
+**现在：**
+
+```typescript
+// 方式1：配合 pageInfoLookup 使用（数学模块自动配置）
+initPageInfo(functionId: string, defaultTitle?: string)
+
+// 方式2：直接提供信息（专注力等模块可以使用）
+initPageInfo({ title: string, desc?: string, functionId: string })
+```
+
+### 配置化的页面信息查找
+
+通过 `PageCommonMethodsConfig` 可以传入：
+
+- `shareConfig`: 模块特定的分享配置
+- `pageInfoLookup`: 页面信息查找函数（可选）
+
+这样不同模块可以使用不同的查找逻辑，而不需要硬编码。
+
+## 使用方式
+
+### 数学模块（无需修改）
+
+所有现有的数学页面继续使用原有方式：
+
+```typescript
+import { createMathPage, CanvasDataState } from '../common/mathPageMixin';
+
+createMathPage({
+    // ...
+    onLoad(options: { id?: string }) {
+        const functionId = options.id || 'addition-5';
+        // 自动从 MATH_FUNCTION_TYPES 中查找
+        this.initPageInfo(functionId, '默认标题');
+    },
+});
+```
+
+### 专注力模块（新）
+
+```typescript
+import { createFocusPage } from '../common/focusPageMixin';
+
+createFocusPage({
+    // ...
+    onLoad(options: { id?: string }) {
+        const functionId = options.id || 'grid-drawing';
+        // 自动从 FOCUS_FUNCTION_TYPES 中查找
+        this.initPageInfo(functionId, '格子仿画');
+    },
+});
+```
+
+### 其他模块（通用方式）
+
+```typescript
+import { createPage, PageCommonMethodsConfig } from '../../base/pageMixin';
+
+const myConfig: PageCommonMethodsConfig = {
+    shareConfig: {
+        title: '我的模块',
+        imageUrl: 'https://example.com/share.png',
+    },
+    pageInfoLookup: (functionId) => {
+        // 自定义查找逻辑
+        return { title: '...', desc: '...' };
+    },
+};
+
+createPage(
+    {
+        // ...
+        onLoad(options: { id?: string }) {
+            // 方式1：使用 lookup 函数
+            this.initPageInfo(options.id || 'default', '默认标题');
+
+            // 方式2：直接提供信息
+            this.initPageInfo({
+                functionId: options.id || 'default',
+                title: '页面标题',
+                desc: '页面描述',
+            });
+        },
+    },
+    myConfig,
+);
+```
+
+## 文件结构
+
+```
+miniprogram/
+├── base/
+│   ├── pageMixin.ts              # 通用页面基类（新增）
+│   └── pageMixin.README.md       # 使用文档（新增）

+│
+└── focusPages/
+    └── common/
+        └── focusPageMixin.ts     # 专注力模块示例（新增）
+```
+
+## 向后兼容性
+
+✅ **所有现有的数学页面无需修改**
+
+因为：
+
+- `mathPageMixin.ts` 保持了相同的导出接口
+- `createMathPage` 函数签名不变
+- `initPageInfo` 方法调用方式不变
+- 所有类型定义都重新导出
+
+## 受影响的文件
+
+### 无需修改的文件
+
+以下数学页面文件无需修改，因为它们使用相同的接口：
+
+- `mathPages/addition/addition.ts`
+- `mathPages/compare/compare.ts`
+- `mathPages/countMatch/countMatch.ts`
+- `mathPages/countingSelect/countingSelect.ts`
+- `mathPages/missingNumber/missingNumber.ts`
+- `mathPages/numberDecompose/numberDecompose.ts`
+- `mathPages/numberFind/numberFind.ts`
+
+### 修改的文件
+
+- ✅ `base/pageMixin.ts` - 新增
+- ✅ `mathPages/common/mathPageMixin.ts` - 重构（保持向后兼容）
+
+## 测试建议
+
+1. 验证所有数学页面功能正常
+2. 验证页面信息（title, desc）正确显示
+3. 验证分享功能正常
+4. 验证 Canvas 初始化正常
+5. 验证图片导出功能正常
+
+## 后续扩展
+
+其他模块（如专注力模块）可以：
+
+1. 创建自己的 `XXXPageMixin.ts` 文件
+2. 定义自己的函数类型和列表
+3. 配置自己的分享信息
+4. 使用 `createXXXPage` 创建页面
+
+这样可以保持代码的模块化和可维护性。

+# 通用页面基类 (pageMixin)
+
+## 概述
+
+`pageMixin.ts` 提供了一个通用的页面基类，可以被不同模块（数学学习、专注力等）共用。它抽象了 Canvas 绘制页面的通用功能。
+
+## 核心功能
+
+- Canvas 初始化和配置
+- 分享功能（小程序分享、朋友圈分享）
+- 图片导出和打印
+- 页面信息初始化
+
+## 使用方法
+
+### 1. 基础用法（不依赖特定的页面信息查找）
+
+```typescript
+import { createPage } from '../../base/pageMixin';
+
+createPage({
+    canvas: null as Canvas | null,
+    ctx: null as RenderingContext | null,
+    // ... 其他属性
+
+    data: {
+        pageTitle: '页面标题',
+        functionId: 'my-function-id',
+        // ... 其他数据
+    },
+
+    onLoad(options: { id?: string }) {
+        const functionId = options.id || 'my-function-id';
+
+        // 方式1：直接提供页面信息
+        this.initPageInfo({
+            functionId,
+            title: '页面标题',
+            desc: '页面描述',
+        });
+
+        // 或者方式2：使用默认标题（需要传入 defaultTitle）
+        this.initPageInfo(functionId, '默认标题');
+    },
+});
+```
+
+### 2. 自定义页面信息查找函数
+
+如果你有多个页面需要共享同一个查找逻辑，可以创建自己的 mixin：
+
+```typescript
+import { createPage, PageCommonMethodsConfig } from '../../base/pageMixin';
+
+// 定义自己的页面信息查找函数
+function myPageInfoLookup(functionId: string) {
+    // 从你的常量或配置中查找
+    const pageInfo = MY_FUNCTION_TYPES.find((item) => item.id === functionId);
+    if (pageInfo) {
+        return {
+            title: pageInfo.title,
+            desc: pageInfo.desc,
+        };
+    }
+    return undefined;
+}
+
+// 使用配置创建页面
+const config: PageCommonMethodsConfig = {
+    shareConfig: {
+        title: '我的模块',
+        imageUrl: 'https://example.com/share.png',
+    },
+    pageInfoLookup: myPageInfoLookup,
+};
+
+createPage(
+    {
+        // ... 页面配置
+        onLoad(options: { id?: string }) {
+            const functionId = options.id || 'default-id';
+            // 现在可以使用简化的调用方式
+            this.initPageInfo(functionId, '默认标题');
+            // 如果有 pageInfoLookup，会自动查找并设置 title 和 desc
+        },
+    },
+    config,
+);
+```
+
+### 3. 数学模块的用法（向后兼容）
+
+数学模块已经封装好了专用的 `mathPageMixin.ts`，可以直接使用：
+
+```typescript
+import { createMathPage, CanvasDataState } from '../common/mathPageMixin';
+
+createMathPage({
+    // ... 页面配置
+    onLoad(options: { id?: string }) {
+        const functionId = options.id || 'addition-5';
+        // 自动从 MATH_FUNCTION_TYPES 中查找
+        this.initPageInfo(functionId, '默认标题');
+    },
+});
+```
+
+## API 说明
+
+### createPage(pageOptions, config?)
+
+创建并注册一个页面。
+
+**参数：**
+
+- `pageOptions`: 页面配置对象
+- `config`: 可选，公共方法配置（见 `PageCommonMethodsConfig`）
+
+### initPageInfo(functionIdOrOptions, defaultTitle?)
+
+初始化页面信息，支持两种调用方式：
+
+**方式1：**
+
+```typescript
+this.initPageInfo(functionId: string, defaultTitle?: string)
+```
+
+- 如果有配置 `pageInfoLookup`，会尝试查找
+- 否则使用 `defaultTitle`
+
+**方式2：**
+
+```typescript
+this.initPageInfo({ title: string, desc?: string, functionId: string })
+```
+
+- 直接提供页面信息，忽略 `pageInfoLookup`
+
+### initCanvas(options)
+
+初始化 Canvas。
+
+**参数：**
+
+- `options.createDrawService`: 创建绘制服务的工厂函数
+- `options.drawServiceOptions`: 绘制服务的选项
+- `options.onCanvasReady`: Canvas 初始化完成后的回调
+
+### exportToPrint()
+
+导出并保存图片（用于打印）。
+
+### getShareOptions()
+
+获取分享配置。
+
+### onShareAppMessage()
+
+微信小程序分享处理函数。
+
+### onShareTimeline()
+
+微信朋友圈分享处理函数。
+
+## 专注力模块使用示例
+
+```typescript
+import { createPage, PageCommonMethodsConfig } from '../../base/pageMixin';
+
+// 专注力模块的函数类型定义
+interface FocusFunctionType {
+    id: string;
+    title: string;
+    desc: string;
+}
+
+// 专注力模块的函数列表
+const FOCUS_FUNCTION_TYPES: FocusFunctionType[] = [
+    {
+        id: 'grid-drawing',
+        title: '格子仿画',
+        desc: '在格子中绘制颜色',
+    },
+    // ... 更多
+];
+
+// 专注力模块的页面信息查找函数
+function focusPageInfoLookup(functionId: string) {
+    const functionItem = FOCUS_FUNCTION_TYPES.find(
+        (item) => item.id === functionId,
+    );
+    if (functionItem) {
+        return {
+            title: functionItem.title,
+            desc: functionItem.desc,
+        };
+    }
+    return undefined;
+}
+
+// 专注力模块的配置
+const focusConfig: PageCommonMethodsConfig = {
+    shareConfig: {
+        title: '涂鸦丫-专注力训练',
+        imageUrl: 'https://cdn.joeyone.cn/doodle/share-img/focus-share.png',
+    },
+    pageInfoLookup: focusPageInfoLookup,
+};
+
+// 创建专注力页面
+createPage(
+    {
+        canvas: null as Canvas | null,
+        // ... 其他配置
+
+        onLoad(options: { id?: string }) {
+            const functionId = options.id || 'grid-drawing';
+            // 自动从 FOCUS_FUNCTION_TYPES 中查找
+            this.initPageInfo(functionId, '格子仿画');
+        },
+    },
+    focusConfig,
+);
+```
+
+## 向后兼容性
+
+所有现有的数学页面无需修改，因为 `mathPageMixin.ts` 保持了相同的接口。

+# mathPages 目录重构方案
+
+## 当前目录结构
+
+```
+mathPages/
+├── addition/           # 页面
+├── compare/            # 页面
+├── countingSelect/     # 页面
+├── countMatch/         # 页面
+├── missingNumber/      # 页面
+├── numberDecompose/    # 页面
+├── numberFind/         # 页面
+├── assets/             # 静态资源
+├── common/             # 公共文件（mixin等）
+├── components/         # 组件
+└── service/            # 服务（Draw相关）
+```
+
+## 问题
+
+- 页面和服务放在同一级，不易区分
+- 目录较多，查找页面不够直观
+- 公共服务散落在不同目录
+
+## 推荐方案：使用 `shared/` 目录
+
+### 重构后的目录结构
+
+```
+mathPages/
+├── addition/           # 页面
+├── compare/            # 页面
+├── countingSelect/     # 页面
+├── countMatch/         # 页面
+├── missingNumber/      # 页面

+    ├── common/         # 公共文件（从 common/ 移动）
+    └── components/     # 组件（从 components/ 移动）
+```
+
+### 优点
+
+1. ✅ **语义清晰**：`shared/` 明确表示共享代码
+2. ✅ **结构清晰**：页面和公共服务分离，一目了然
+3. ✅ **易于维护**：所有公共服务集中在一个目录下
+4. ✅ **符合常见实践**：`shared/` 在很多项目中都有使用
+5. ✅ **扩展性好**：未来可以添加 `shared/utils/`、`shared/types/` 等
+
+### 需要修改的导入路径
+
+#### 页面文件中的导入
+
+**之前：**
+
+```typescript
+import AdditionDraw from '../service/additionDraw';
+import { createMathPage } from '../common/mathPageMixin';
+import MathBottomButtons from '../components/math-bottom-buttons/math-bottom-buttons';
+```
+
+**之后：**
+
+```typescript
+import AdditionDraw from '../shared/service/additionDraw';
+import { createMathPage } from '../shared/common/mathPageMixin';
+import MathBottomButtons from '../shared/components/math-bottom-buttons/math-bottom-buttons';
+```
+
+#### service 文件之间的导入
+
+**之前：**
+
+```typescript
+import { BaseDrawService } from './baseMathDraw';
+```
+
+**之后：**
+
+```typescript
+import { BaseDrawService } from './baseMathDraw';
+// 或者如果跨目录
+import { BaseDrawService } from '../baseMathDraw';
+```
+
+## 备选方案：使用 `lib/` 目录
+
+如果不想用 `shared/`，也可以考虑 `lib/`：
+
+```
+mathPages/
+├── addition/
+├── compare/
+├── ...
+├── assets/
+└── lib/              # 公共服务目录
+    ├── service/
+    ├── common/
+    └── components/
+```
+
+**优点：**
+
+- 简洁
+- 表示库文件
+
+**缺点：**
+
+- `lib/` 通常用于第三方库或编译产物
+- 语义上不如 `shared/` 清晰
+
+## 备选方案：使用 `core/` 目录
+
+```
+mathPages/
+├── addition/
+├── compare/
+├── ...
+├── assets/
+└── core/             # 核心功能目录
+    ├── service/
+    ├── common/
+    └── components/
+```
+
+**优点：**
+
+- 表示核心功能
+
+**缺点：**
+
+- `core/` 通常用于框架核心，不太适合业务代码
+
+## 迁移步骤
+
+1. **创建 `shared/` 目录**
+2. **移动目录**
+    - `service/` → `shared/service/`
+    - `common/` → `shared/common/`
+    - `components/` → `shared/components/`
+3. **批量更新导入路径**
+    - 所有页面文件中的 `../service/` → `../shared/service/`
+    - 所有页面文件中的 `../common/` → `../shared/common/`
+    - 所有页面文件中的 `../components/` → `../shared/components/`
+    - 检查 `shared/` 内部文件的相互导入
+4. **更新配置文件**
+    - 检查是否有路径配置需要更新（如 `app.json` 中的组件路径）
+5. **测试验证**
+    - 确保所有页面功能正常
+    - 确保导入路径正确
+
+## 推荐使用 `shared/` 目录
+
+综合考虑，**推荐使用 `shared/` 目录**，因为：
+
+- 语义最清晰
+- 符合常见实践
+- 易于理解和维护

-# 汉字选择页面 (wordDemo)
-
-## 功能描述
-
-这是一个汉字输入和选择的页面，主要包含以下功能：
-
-### 上部区域 - 汉字输入
-
-- 输入框：可以输入任意汉字（最多10个字符）
-- 生成按钮：点击后将输入的汉字添加到已选择列表中
-- **汉字校验**：自动校验输入内容是否为汉字，非汉字会提示错误
-- **智能分割**：支持输入多个汉字，自动分割为单个汉字存储
-
-### 中部区域 - 已选择的汉字
-
-- 显示所有已选择的汉字
-- 每个汉字都有删除按钮（×）
-- 清空按钮：一键清空所有已选择的汉字
-- 显示已选择汉字的数量
-
-### 下部区域 - 可选汉字
-
-- 从 `demo/grade3.json` 文件中提取前30个汉字
-- 以6列网格形式展示
-- 已选择的汉字会显示为禁用状态
-- 点击未选择的汉字可以添加到列表中
-
-## 核心特性
-
-### 🔍 **汉字校验**
-
-- 使用Unicode范围 `\u4e00-\u9fff` 校验汉字
-- 非汉字输入会显示Toast提示"请输入汉字"
-- 确保 `wordList` 中只存储纯汉字
-
-### ✂️ **智能分割**
-
-- 支持输入多个汉字（如："你好世界"）
-- 自动分割为单个汉字：["你", "好", "世", "界"]
-- 过滤重复汉字，避免重复添加
-- 显示实际添加的汉字数量
-
-### 💾 **数据管理**
-
-- `wordList` 中每个元素都是单个汉字
-- 自动去重，避免重复存储
-- 支持批量添加和单个删除
-
-## 数据结构
-
-- `inputWord`: 输入框中的汉字
-- `wordList`: 已选择的汉字列表（string[]类型，每个元素为单个汉字）
-- `availableWords`: 从grade3.json中提取的前30个汉字
-
-## 使用方法
-
-1. 在输入框中输入汉字（支持多个汉字）
-2. 点击"生成"按钮，系统自动校验和分割
-3. 点击下方网格中的汉字进行选择
-4. 已选择的汉字会显示在上方，可以单独删除或一键清空
-5. 所有选择的汉字都存储在 `this.data.wordList` 中
-
-## 技术实现
-
-### 汉字校验
-
-```typescript
-isChineseText(text: string): boolean {
-    const chineseRegex = /^[\u4e00-\u9fff]+$/;
-    return chineseRegex.test(text);
-}
-```
-
-### 文本分割
-
-```typescript
-splitToSingleChars(text: string): string[] {
-    const chineseRegex = /[\u4e00-\u9fff]/g;
-    const matches = text.match(chineseRegex);
-    return matches || [];
-}
-```
-
-## 文件结构
-
-- `index.ts`: 页面逻辑文件
-- `index.wxml`: 页面模板文件
-- `index.less`: 页面样式文件
-- `index.json`: 页面配置文件

+# Service 目录绘制服务改造完成总结
+
+## 改造目标
+
+将所有绘制服务统一使用 `baseDraw.ts` 和 `baseHeaderDraw.ts` 作为基类，提取公共部分并统一 Header 绘制。
+
+## 完成的工作
+
+### 1. ✅ 统一基础服务类
+
+所有绘制服务现在都继承自 `BaseDrawService`（位于 `service/baseDraw.ts`）：
+
+- ✅ `TextDrawService` - 文字涂色服务
+- ✅ `ShapeDrawService` - 图形涂色服务
+- ✅ `FindWordDrawService` - 找字涂色服务
+- ✅ `WordDrawService` - 田字格练字服务
+
+### 2. ✅ 统一 Header 绘制
+
+所有服务使用统一的 Header 绘制功能（位于 `service/baseHeaderDraw.ts`）：
+
+- `drawBaseHeader()` - 完整 Header（包含 Logo、应用名称、标题、副标题）
+- `drawBaseMiniHeader()` - 迷你 Header（简化版本）
+
+### 3. ✅ 统一使用逻辑像素
+
+所有服务现在使用逻辑像素（尺寸除以3），与数学模块保持一致：
+
+- Canvas 尺寸通过 `setPaper()` 统一处理 DPR（device pixel ratio）
+- 所有绘制代码中的硬编码尺寸都已转换为逻辑像素
+- 坐标计算统一使用 `this.canvasWidth` 和 `this.canvasHeight`
+
+### 4. ✅ 清理重复代码
+
+删除了以下重复方法，统一使用基类实现：
+
+- `setPrintConfig()` - 统一在基类中实现
+- `setPaper()` - 统一在基类中实现
+- `clear()` - 统一在基类中实现
+- `drawHeader()` / `drawMiniHeader()` - 统一在基类中实现
+- `drawDivider()` - 统一在基类中实现
+
+## 改造详情
+
+### TextDrawService
+
+**改造内容：**
+
+- 继承 `BaseDrawService`
+- 移除自定义的 `setPaper()`, `clear()`, `drawHeader()`, `drawMiniHeader()`
+- 所有尺寸转换为逻辑像素：
+    - 半径：80 → 27
+    - 字体：72px → 24px, 48px → 16px
+    - 边距：80 → 27, 220 → 73
+    - 坐标：200 → 67, 304 → 101
+
+**关键方法：**
+
+- `drawLegend()` - 绘制示例区域
+- `drawContent()` - 绘制内容区域
+
+### ShapeDrawService
+
+**改造内容：**
+
+- 继承 `BaseDrawService`
+- 移除自定义的绘制方法
+- 所有尺寸转换为逻辑像素：
+    - 图形大小：200 → 67, 180 → 60
+    - 字体：36px → 12px
+    - 间距：120 → 40, 160 → 53
+
+**关键方法：**
+
+- `drawLegend()` - 绘制示例区域
+- `drawContent()` - 绘制内容区域
+
+### FindWordDrawService
+
+**改造内容：**
+
+- 继承 `BaseDrawService`
+- 移除自定义的绘制方法
+- 所有尺寸转换为逻辑像素：
+    - 半径：80 → 27
+    - 字体：72px → 24px
+    - 模板坐标转换：`pos.x / 3`, `pos.y / 3`
+
+**关键方法：**
+
+- `drawContent()` - 绘制找字内容（中心大字 + 四周字符）
+
+**特殊处理：**
+
+- `getPositionsFromTemplate()` 函数中增加了坐标转换逻辑，将模板中的原始像素坐标转换为逻辑像素
+
+### WordDrawService
+
+**改造内容：**
+
+- 继承 `BaseDrawService`
+- 移除自定义的绘制方法
+- 所有尺寸转换为逻辑像素：
+    - 田字格大小：140 → 47
+    - 边距：120 → 40, 50 → 17
+    - 间距：24 → 8, 36 → 12
+
+**关键方法：**
+
+- `drawLayout()` - 绘制页眉和基础布局
+- `drawContent()` - 绘制田字格和练字内容
+- `drawPracticeContent()` - 绘制练习内容
+- `getMaxGridLayout()` - 计算最大网格布局
+
+## 架构优势
+
+1. ✅ **代码复用**：公共逻辑集中在 `BaseDrawService` 基类中
+2. ✅ **统一 Header**：所有服务使用相同的 Header 绘制逻辑
+3. ✅ **统一像素标准**：所有服务使用逻辑像素，保持一致
+4. ✅ **易于维护**：修改 Header 或基础功能只需修改一个地方
+5. ✅ **类型安全**：TypeScript 类型支持完整
+
+## 注意事项
+
+### 坐标转换
+
+所有硬编码的尺寸值都已转换为逻辑像素（除以3）：
+
+```typescript
+// 原始像素 → 逻辑像素
+const radius = 27; // 80/3≈27
+const fontSize = 24; // 72/3=24
+const margin = 40; // 120/3=40
+```
+
+### 模板坐标转换
+
+`FindWordDrawService` 中使用的 `POSITION_TEMPLATES` 坐标是基于原始像素的，需要在使用时转换：
+
+```typescript
+const x = centerX + pos.x / 3; // 转换为逻辑像素
+const y = centerY + pos.y / 3; // 转换为逻辑像素
+```
+
+### Canvas 尺寸
+
+所有服务现在统一使用：
+
+- `this.canvasWidth` - 逻辑像素宽度
+- `this.canvasHeight` - 逻辑像素高度
+
+这些值在 `setPaper()` 中设置，已经处理了 DPR。
+
+## 向后兼容性
+
+- ✅ `drawServiceFactory.ts` 接口无需修改
+- ✅ 所有服务的公共接口保持不变
+- ✅ 只改变了内部实现方式
+
+## 后续优化建议
+
+1. 可以考虑将 `findWordTemplate.ts` 中的坐标模板也转换为逻辑像素，避免运行时转换
+2. 可以考虑创建更多的基础绘制工具函数（如绘制表格、绘制网格等）
+3. 可以考虑支持更多 Paper 尺寸（目前仅支持 A4）
+
+## 测试建议
+
+1. 验证所有绘制服务功能正常
+2. 验证 Header 正确显示
+3. 验证尺寸和比例正确
+4. 验证不同 Header 类型（wechat, LogoImage, noLogoImage, minimal）
+5. 验证打印输出质量

+# 绘制服务重构总结
+
+## 重构目标
+
+基于 `baseDraw.ts` 和 `baseHeaderDraw.ts` 统一所有绘制服务的公共部分，提取并统一 Header 绘制功能。
+
+## 完成的工作
+
+### 1. ✅ 统一基础服务类
+
+所有绘制服务现在都继承自 `BaseDrawService`（位于 `service/baseDraw.ts`）：
+
+- ✅ `AdditionDraw` - 加减法计算
+- ✅ `CompareDraw` - 数一数比大小
+- ✅ `CountMatchDraw` - 数一数连一连
+- ✅ `CountingSelectDraw` - 数一数选一选/填一填
+- ✅ `MissingNumberDraw` - 填上缺少的数字
+- ✅ `NumberColorDraw` - 按数字涂颜色
+- ✅ `NumberDecomposeDraw` - 10以内数的分与合
+- ✅ `NumberFindDraw` - 数字涂色（找数字、写数字）
+
+### 2. ✅ 统一 Header 绘制
+
+所有服务使用统一的 Header 绘制功能（位于 `service/baseHeaderDraw.ts`）：
+
+- `drawBaseHeader()` - 完整 Header（包含 Logo、应用名称、标题、副标题）
+- `drawBaseMiniHeader()` - 迷你 Header（简化版本）
+
+### 3. ✅ 修复相关导入
+
+- ✅ 修复 `base/pageMixin.ts` 中的导入路径
+    - 从 `../mathPages/service/baseMathDraw` 改为 `../service/baseDraw`
+
+### 4. ✅ 清理旧文件
+
+- ✅ 删除 `mathPages/shared/service/baseMathDraw.ts`（已被 `BaseDrawService` 替代）
+- ✅ 删除 `mathPages/shared/service/mathHeaderDraw.ts`（已被 `baseHeaderDraw.ts` 替代）
+
+## 架构设计
+
+### 基础服务类 (`BaseDrawService`)
+
+提供以下公共功能：
+
+```typescript
+class BaseDrawService {
+    // Canvas 和上下文
+    canvas: Canvas;
+    ctx: RenderingContext;
+
+    // 配置
+    options: Record<string, any>;
+    paperSize: PaperSize;
+    headerType: PrintHeader;
+
+    // 坐标管理
+    currentX: number;
+    currentY: number;
+    canvasWidth: number;
+    canvasHeight: number;
+
+    // 公共方法
+    setPrintConfig(); // 设置打印配置
+    setPaper(); // 设置 Paper 尺寸
+    clear(); // 清除画布
+    drawHeader(); // 绘制完整 Header
+    drawMiniHeader(); // 绘制迷你 Header
+    drawDivider(); // 绘制分割线
+}
+```
+
+### Header 绘制 (`baseHeaderDraw.ts`)
+
+提供统一的 Header 绘制函数：
+
+- `drawBaseHeader()` - 支持多种 Header 类型：
+
+    - `wechat` - 微信小程序码（默认）
+    - `LogoImage` - Logo 图片
+    - `noLogoImage` - 无 Logo
+    - `minimal` - 极简模式
+
+- `drawBaseMiniHeader()` - 迷你版本，居中显示
+
+### 具体服务类
+
+每个具体服务类：
+
+1. **继承 `BaseDrawService`**
+2. **实现 `draw()` 方法**，通常包含以下步骤：
+
+    ```typescript
+    async draw(data: any) {
+        // 1. 设置配置
+        this.setPrintConfig();
+
+        // 2. 清除并设置 Paper
+        this.clear();
+        this.setPaper();
+
+        // 3. 绘制 Header
+        if (this.headerType !== 'minimal') {
+            await this.drawHeader();
+        } else {
+            this.drawMiniHeader();
+        }
+
+        // 4. 绘制分割线
+        this.drawDivider();
+
+        // 5. 绘制内容（调用 ContentDraw 函数）
+        await drawXXXContent({
+            canvas: this.canvas,
+            ctx: this.ctx,
+            data: data,
+            canvasWidth: this.canvasWidth,
+            startY: this.currentY,
+        });
+    }
+    ```
+
+3. **使用 ContentDraw 函数**绘制具体内容（例如 `drawAdditionContent`）
+
+## 文件结构

+
+## 使用示例
+
+### 创建新的绘制服务
+
+```typescript
+import { BaseDrawService } from '../../../service/baseDraw';
+import { drawMyContent } from './myContentDraw';
+
+class MyDraw extends BaseDrawService {
+    myData: any;
+
+    constructor(
+        canvas: Canvas,
+        ctx: RenderingContext,
+        options?: Record<string, any>,
+    ) {
+        super(canvas, ctx, options);
+        this.myData = null;
+    }
+
+    async draw(myData: any) {
+        if (!myData) return;
+
+        this.setPrintConfig();
+        this.myData = myData;
+        this.clear();
+        this.setPaper();
+
+        // 绘制 Header
+        if (this.headerType !== 'minimal') {
+            await this.drawHeader();
+        } else {
+            this.drawMiniHeader();
+        }
+
+        // 绘制内容
+        this.drawDivider();
+        await drawMyContent({
+            canvas: this.canvas,
+            ctx: this.ctx,
+            data: this.myData,
+            canvasWidth: this.canvasWidth,
+            startY: this.currentY,
+        });
+    }
+}
+
+export default MyDraw;
+```
+
+## 优势
+
+1. ✅ **代码复用**：公共逻辑集中在基类中
+2. ✅ **统一 Header**：所有服务使用相同的 Header 绘制逻辑
+3. ✅ **易于维护**：修改 Header 只需修改一个地方
+4. ✅ **类型安全**：TypeScript 类型支持完整
+5. ✅ **扩展性好**：新增服务只需继承基类并实现 `draw()` 方法
+
+## 注意事项
+
+1. **ContentDraw 函数**：具体内容绘制函数通常以 `drawXXXContent` 命名，接收参数包括 `canvas`、`ctx`、数据、`canvasWidth`、`startY` 等
+2. **坐标管理**：使用 `this.currentY` 管理垂直坐标，ContentDraw 函数需要更新该值
+3. **Header 类型**：通过 `this.headerType` 判断使用完整 Header 还是迷你 Header
+4. **逻辑像素**：所有尺寸都已除以 3，使用逻辑像素
+
+## 后续优化建议
+
+1. 考虑将 ContentDraw 函数也提取到 `service/` 目录下的统一位置
+2. 可以考虑创建更多的基础绘制工具函数（如绘制表格、绘制网格等）
+3. 可以考虑支持更多 Paper 尺寸（目前仅支持 A4）
