python代码

语言：python 3

用法：点击运行后，弹出窗口，选择文件夹，程序运行会将文件夹内的所有PPT文件全部转换成PPT长图，图片名称与PPT文件名称相同，保存位置相同。

如运行中报错，需要自行根据报错内容按照缺失的库

共分享两种代码，可以尝试运行。

代码1，需安装库

#安装库 pip install pyautogui #安装库 pip install pillow

import os import comtypes.client from tkinter import Tk, filedialog from PIL import Image def ppt_to_images(ppt_file): try: # 导入comtypes.client模块并创建PowerPoint应用程序对象 powerpoint = comtypes.client.CreateObject("Powerpoint.Application") # 设置PowerPoint应用程序为可见状态，便于观察操作过程（可选）,修改为0后报错 #powerpoint.Visible = 1 # 打开PPT文件，并返回Presentation对象 presentation = powerpoint.Presentations.Open(ppt_file) for i, slide in enumerate(presentation.slides): #slide是幻灯片序列 slide.Export(f"slide_{i}.png", "PNG") # 关闭PPT文件 presentation.Close() # 退出PowerPoint应用程序 powerpoint.Quit() presentation = None print(ppt_file+"分图完成！") except Exception as e: print("分图时发生错误：", str(e)) def merge_images(directory, png_file): try: Image.MAX_IMAGE_PIXELS = 2 ** 40 images = [] # 存储图片对象 for file in os.listdir(directory): file_path = os.path.join(directory, file) if os.path.isfile(file_path) and file.lower().endswith(".png"): image = Image.open(file_path) images.append(image) if len(images) == 0: print("未找到PNG格式的图片文件") return None max_width = max(image.size[0] for image in images) # 获取最大宽度 total_height = sum(image.size[1] for image in images) # 计算总高度 final_image = Image.new("RGBA", (max_width, total_height), (0, 0, 0, 0)) # 创建最终图像 # 逐个粘贴图片到最终图像中 y_offset = 0 for image in images: final_image.paste(image, (0, y_offset)) y_offset += image.size[1] final_image.save(png_file) print("已生成图片"+png_file) if final_image: for file in os.listdir(directory): file_path = os.path.join(directory, file) if os.path.isfile(file_path) and file.lower().endswith(".png") and "slide" in file: os.remove(file_path) print("已删除图片"+file) except Exception as e: print("合并图片时发生错误：", str(e)) def select_directory(): try: root = Tk() root.withdraw() directory = filedialog.askdirectory(title="选择目录") ppt_files = [f for f in os.listdir(directory) if f.endswith('.pptx')or f.endswith('.ppt')] for ppt_file in ppt_files: try: #print("directory" + directory) if ppt_file.lower().endswith(".pptx"): png_file = os.path.join(directory, ppt_file[:-5] + ".png") ppt_to_images(ppt_file) # PPT to image merge_images(directory, png_file) # image to images elif ppt_file.lower().endswith(".ppt"): png_file = os.path.join(directory, ppt_file[:-4] + ".png") ppt_to_images(ppt_file) # PPT to image merge_images(directory, png_file) # image to images except Exception as e: print("处理PPT文件时发生错误，跳过该文件：", str(e)) print("转换完成！") except Exception as e: print("选择目录并转换PPT文件时发生错误：", str(e)) # 选择目录并转换PPT到PDF格式，再将PDF转换为长图 select_directory()

代码2如下：

import os import comtypes.client from tkinter import Tk, filedialog from pptx import Presentation from PIL import Image #PPT转换成图片 def ppt_to_images(ppt_file, png_file): #presentation = powerpoint.Presentations.Open(ppt_file) presentation = Presentation(os.path.join(png_file, ppt_file)) for i, slide in enumerate(presentation.slides): #slide是幻灯片序列 slide.export(f"{png_file}/slide_{i}.png") #将PPT转换成图片并保存到目录下 print("PPT转换为图像完成！") #将图片拼接成长图 def merge_images(ppt_path, output_file): images = [Image.open(f"{ppt_path}/{img}") for img in os.listdir(ppt_path) if img.endswith(".png")] widths, heights = zip(*(img.size for img in images)) total_height = sum(heights) max_width = max(widths) merged_image = Image.new("RGB", (max_width, total_height)) y_offset = 0 for img in images: merged_image.paste(img, (0, y_offset)) y_offset += img.size[1] merged_image.save(output_file) print("图像拼接完成！") def ppt_to_pdf(ppt_path, pdf_file): #ppt路径和pdf的路径 # 导入comtypes.client模块并创建PowerPoint应用程序对象 powerpoint = comtypes.client.CreateObject("Powerpoint.Application") # 设置PowerPoint应用程序为可见状态，便于观察操作过程（可选）,修改为0后报错 powerpoint.Visible = 1 # 打开PPT文件，并返回Presentation对象 presentation = powerpoint.Presentations.Open(ppt_path) # 将打开的PPT文件导出为PDF文件（第二个参数2表示导出为PDF格式） presentation.ExportAsFixedFormat(pdf_file, 2) # 输出转换完成的信息 print(ppt_path + "转PDF完成！") def select_directory(): root = Tk() root.withdraw() directory = filedialog.askdirectory(title="选择目录") ppt_files = [f for f in os.listdir(directory) if f.endswith('.pptx')] for ppt_file in ppt_files: ppt_path = os.path.join(directory, ppt_file) #ppt_path ppt的路径,拼接ppt pdf_file = os.path.join(directory, ppt_file[:-4] + ".pdf") #pdf文件 png_file= os.path.join(directory, ppt_file[:-4] + ".png") ppt_to_pdf(ppt_path, pdf_file) print("转换完成！") # 选择目录并转换PPT到PDF格式，再将PDF转换为长图 select_directory()
