网上搜了下很多方法都是过期的，这里贴下我的方法
根据 pymupdf – Pixmap.tobytes
https://pymupdf.readthedocs.io/en/latest/pixmap.html#Pixmap.tobytes

核心方法

def pdf2png(pdfPath, img_dir, zoom_x=1,zoom_y=1,rotation_angle=0):
    # 打开PDF文件
    pdf = fitz.open(pdfPath)


    # 逐页读取PDF
    for idx in range(0, pdf.page_count):
        idx += 1
        page = pdf[idx] 
        trans = fitz.Matrix(zoom_x, zoom_y).preRotate(rotation_angle) 
        pm = page.get_pixmap(matrix=trans, alpha=False, dpi=200)
        

        bt = pm.tobytes()
 
        img_path = os.path.join(img_dir, f'{idx}.png')
        with open(img_path, 'wb') as f:f.write(bt)
        
    pdf.close()

整个处理文件
