**绘制矢量图并导出为EMF格式**

在本文中，我们将介绍如何使用Python语言绘制矢量图，并将其导出为EMF（Enhanced Metafile）格式。我们将使用Matplotlib库来绘制图形。

### 一、安装所需的库首先，我们需要安装所需的库，包括Matplotlib和Reportlab。

import matplotlib.pyplot as pltfrom reportlab.lib.pagesizes import letterfrom reportlab.pdfgen import canvas

# 绘制圆形fig, ax = plt.subplots()
circle = plt.Circle((0.5,0.5),0.4, edgecolor='black', facecolor='none')
ax.add_artist(circle)
plt.axis('equal') # 等比缩放

# 导出为EMF格式c = canvas.Canvas("vector_graph.emf", pagesize=letter)
ax = plt.gca()
plt.savefig(c, format="emf")

import matplotlib.pyplot as pltfrom reportlab.lib.pagesizes import letterfrom reportlab.pdfgen import canvas# 绘制圆形fig, ax = plt.subplots()
circle = plt.Circle((0.5,0.5),0.4, edgecolor='black', facecolor='none')
ax.add_artist(circle)
plt.axis('equal') # 等比缩放# 导出为EMF格式c = canvas.Canvas("vector_graph.emf", pagesize=letter)
ax = plt.gca()
plt.savefig(c, format="emf")

print("图形已成功导出为EMF格式")
