[PHP5] Thumbnail Class
원래 십여년전(?)부터 뜯어고쳐 오며 사용하던 소스를 좀 정리했다. 이전에 GD를 직접 컨트롤 했었는데 조금 찾아보니 WideImage 란 라리브러리가 있기에, 그걸로 바꾸다보니 워낙 기능이 막강해서 정작 내가 만든 클래스는 Wrapping Class가 되어 버렸다 ;; 어쨋든, 밤하늘의 별처럼 널려있는 썸네일 라이브러리들을 마다하고 만든 이유는 단 두가지 이다. 썸네일의 종횡비율에 따라 중앙부분을 기준으로 Crop해서 썸네일을 만들어 주는 기능 PNG포맷에서 Resizing시 원본의 Alpha Channel을 유지 해 주는 기능 그 이외에는 잡다한 기능을 다 빼 버렸다. 복잡해지면 오래 못쓰므로… Licence : GNU LGPL 2.1 Copyright (C) 2013 Aiden, Kihyun Kim.
