PDF2ExamApi - PDF Examination Question Extraction Tool

Features

PDF2Exam: Đây đơn giản là 1 tool để convert đề pdf thành dạng ảnh (base64image) Toàn bộ code được tôi sử dụng ở đây đều thuộc về github này: https://github.com/edmicro-tech/PDF2Exam (xin cảm ơn tác giả rất nhiều)
Vậy vì sao có PDF2ExamApi?
Vì tôi là 1 dev .net nên rất khó để áp dụng được tool của tác giả vào phần mềm của mình, vì vậy tôi học cách viết python (trong khoảng 2h) và trả về dưới dạng api để có thể đáp ứng được yêu cầu của mình.
(*) Lưu ý: Phần code này có thể có rất nhiều bug do tôi mới học ngôn ngữ python đc vài giờ, và chỉ để đáp ứng đc yêu cầu công việc của tôi!
