이 객체 내의 데이터를 지정된 콘텐츠 유형으로 변환된 blob으로 반환합니다. 이 메서드는 파일 이름에 적절한 확장자(예: 'myfile.pdf')를 추가합니다. 그러나 마지막 마침표 (있는 경우) 뒤에 오는 파일 이름 부분이 대체해야 할 기존 확장 프로그램이라고 가정합니다. 따라서 'ShoppingList.12.25.2014'가 'ShoppingList.12.25.pdf'가 됩니다.
전환의 일일 할당량을 보려면 Google 서비스 할당량을 참고하세요. 새로 생성된 Google Workspace 도메인에는 일시적으로 더 엄격한 할당량이 적용될 수 있습니다.

변환할 MIME 유형입니다. 대부분의 blob의 경우 'application/pdf'만 유효한 옵션입니다. BMP, GIF, JPEG 또는 PNG 형식의 이미지의 경우 'image/bmp', 'image/gif', 'image/jpeg' 또는 'image/png'도 유효합니다. Google Docs 문서의 경우 'text/markdown'도 유효합니다.
