보고서 실험실과 함께 PDF에 PNG를 추가하려면 어떻게해야합니까?

Question

보고서 연구실에서 일하고 있습니다. 오리너구리와 함께 PNG 이미지를 추가 할 수 없습니다. 여기에서 일부 샘플 코드는 http://www.tylerlesmann.com/2009/jan/28/writing-pdfs-python-adding-images/이고 추가 오류가 있습니다. 그 png

내가 작동하게 도와 줄 수 있습니까?

Answer 1

당신은, 예를 들어와, PIL (Python Imaging Library)를 설치해야합니다

pip install PIL 

나는 PIL를 가져 오는 실패, 그것은 이미지 = 없음을 설정하지 추측하고있다. reportlab 소스를 쉽게 탐색 할 수 있다면 확인해 보겠습니다.

편집 : 여기에 우리가 간다 :

try: 
    import Image 
    if PIL_WARNINGS: warnOnce('Python Imaging Library not available as package; upgrade your installation!') 
except ImportError, errMsg: 
    _checkImportError(errMsg) 
    Image = None
