國中數學幾何圖形技能(jh-math-geometry)

技能概覽

本技能生成適合試卷、簡報、教材的幾何 SVG 圖形,並輸出為 PNG 圖片檔, 可直接插入 Word 文件或 PowerPoint 投影片。

核心腳本位置(請在任何使用前確認):

GEOM_DIR=""
for d in /mnt/skills/user/jh-math-geometry/scripts \
          /tmp/jh-math-geometry/scripts; do
  [ -f "$d/geometry_renderer.py" ] && GEOM_DIR="$d" && break
done
echo "腳本目錄:$GEOM_DIR"

處理流程

Step 1:理解需求

根據使用者的描述,判斷需要哪些圖形。若不確定,先快速確認:

  • 哪個單元(三角形/四邊形/圓/立體...)?
  • 需要標哪些字母/數字?
  • 是否有特殊標記(直角符號、等邊刻度、角弧)?
  • 輸出目標:Word、PPTX 或純圖片下載?

Step 2:建立圖形規格 JSON

依需求建立 spec,儲存至 /home/claude/geometry_spec.json:

{
  "figures": [
    {
      "id": "fig1",
      "type": "triangle",
      "config": {
        "subtype": "right",
        "vertex_labels": ["A", "B", "C"],
        "right_angle_at": "C",
        "side_labels": {"AB": "5", "BC": "3", "CA": "4"}
      },
      "canvas": {"width": 280, "height": 220}
    }
  ],
  "options": {"format": "png", "dpi": 150}
}

> 詳細參數見 references/figure-catalog.md(用 view 工具讀取)。

Step 3:安裝依賴並執行渲染

pip install cairosvg python-docx python-pptx --break-system-packages -q

mkdir -p /home/claude/geometry_output

python3 "$GEOM_DIR/geometry_renderer.py" \
    /home/claude/geometry_spec.json \
    /home/claude/geometry_output/

ls /home/claude/geometry_output/

Step 4:視覺確認

# 用 view 工具看 SVG(快速確認)

使用 view 工具查看產生的 .svg 檔案確認圖形是否正確。 若有錯誤(標籤偏移、比例不佳),調整 config 後重新執行。

Step 5:輸出

純圖片下載
cp /home/claude/geometry_output/fig1.png /mnt/user-data/outputs/
插入 Word
python3 -  /home/claude/geometry_spec.json << 'SPEC'
{
  "figures": [
    {"id": "q3_fig", "type": "triangle", "config": {...}, "canvas": {"width":250,"height":200}}
  ],
  "options": {"format": "png", "dpi": 150}
}
SPEC

# 3. 渲染
mkdir -p /home/claude/geometry_output
python3 "$GEOM_DIR/geometry_renderer.py" /home/claude/geometry_spec.json /home/claude/geometry_output/

# 4. 取得 PNG 路徑供插入
FIGURE_PNG="/home/claude/geometry_output/q3_fig.png"

圖形類型速查表

| type 值 | 說明 | 常用 subtype | |---------|------|------------| | triangle | 三角形 | general right isosceles equilateral | | quadrilateral | 四邊形 | parallelogram rectangle rhombus square trapezoid right_trapezoid | | circle | 圓 | (無 subtype,用 elements 控制)| | coordinate_plane | 坐標平面 | (含直線、拋物線、點、線段)| | solid_3d | 立體圖形 | rectangular_prism cylinder cone triangular_prism square_pyramid triangular_pyramid | | parallel_lines | 平行線截角 | (n_parallel 控制條數)| | triangle_center | 三角形的心 | centroid circumcenter incenter | | similar_triangles | 相似三角形 | (triangle1 + triangle2 各自設定)|


標記系統

| 功能 | 參數 | 說明 | |------|------|------| | 頂點標籤 | vertex_labels | 預設 ["A","B","C"] | | 直角符號 | right_angle_at | 指定頂點 | | 角弧 | angle_arcs | {"A":1} = 一條弧,{"A":2} = 兩條弧(全等角)| | 等邊刻度 | equal_marks | {"AB":1,"CD":1} = 同一組,{"EF":2} = 另一組 | | 邊長/邊名 | side_labels | {"AB":"5"} 或 {"AB":"a"} | | 虛線邊 | dashed_sides | ["AB"] | | 高 | altitude_from | 從指定頂點畫高 | | 中線 | median_from | 從指定頂點畫中線 |


參考資料位置

| 需要什麼 | 讀取哪個檔案 | |----------|-------------| | 所有圖形類型的完整參數 + 快速複製範例 | references/figure-catalog.md | | SVG 產生引擎原始碼 | scripts/geometry_renderer.py | | SVG → PNG 轉換 | scripts/svg_to_image.py | | 插入 Word 的函式 | scripts/insert_to_docx.py | | 插入 PPTX 的函式 | scripts/insert_to_pptx.py |


注意事項

  1. cairosvg 安裝:每次新對話開始前都要重新 pip install
  2. 座標確認:用 view 工具看 .svg 確認後再插入文件
  3. 畫布尺寸:試卷用圖建議 280×220;簡報用圖建議 360×280
  4. 字體:SVG 使用 serif,匯出 PNG 後在 Word/PPTX 中外觀一致
  5. 多圖批次:figures 陣列可一次放多個圖形,manifest.json 記錄所有輸出路徑
