PCB坐标涨缩工具

# 基本用法
curl -X POST https://www.binwindai.com/api/stretch \
  -F "file=@input.g7r" \
  -F "x_factor=1.00022" \
  -F "y_factor=1.00008" \
  -o output.g7r

# 中心拉伸（填毫米坐标,自动识别文件刻度换算）
curl -X POST https://www.binwindai.com/api/stretch \
  -F "file=@input.g7r" \
  -F "x_factor=1.00022" \

  -F "center_x_mm=50.0" \
  -F "center_y_mm=30.0" \
  -F "scale=10000" \
  -o output.g7r

# 只上传文件（使用默认系数）
