[PDF를 ppt 바꾸기] 이미지화해서 ppt에 올리기

 

 

1. pdf를 ppt로 바꾸기

 

 

pdf 내용에 몇 가지 첨가하거나 수정하고 싶을 때  

 

사실 텍스트까지 읽어주면 좋지만 

아직 오류가 많이 나서 

 

이미지만 복사하고 

이미지 복사한 슬라이드 위에 텍스트 박스나 도형을 올리는 방식으로 수정하기로 결정 

 

 

 

 

2.pptx 패키지 활용 

 

 

pdf를 넣어서 pptx (이미지만 올린 간단한 ppt)를 만드는 코드

설치해야할 패키지들 

 

 

pip install pytesseract python-pptx pillow
pip install pdf2image tqdm PyPDF2
sudo apt update
sudo apt install poppler-utils

 

 

pip install pytesseract python-pptx pillow
pip install pdf2image tqdm PyPDF2
sudo apt update
sudo apt install poppler-utils

 

 

위의 패키지들을 실행하는 환경에 설치한다

main.py라는 이름의 파일에 저장하고 

python main.py를 실행

 

만약 conda env 를 써서 import 오류가 난다면, 

/home/{user}/miniconda3/envs/{env name}/bin/python 을 앞에 붙여서 실행한다
