import fitz


def pdf2img(pdf_path, zoom_x, zoom_y):
    doc = fitz.open(pdf_path)  # 打开文档
    for page in doc:  # 遍历页面
        pix = page.get_pixmap(matrix=fitz.Matrix(zoom_x, zoom_y))  # 将页面渲染为图片
        pix.writePNG(f'page-{page.number+1}.png')  # 将图像存储为PNG格式
    doc.close()  # 关闭文档

• pdf_path: pdfThe path of the document to be converted
• zoom_x: xThe scaling factor of the matrix in the direction
• zoom_y: yThe scaling factor of the matrix in the direction
