갤러리 게시판 리스트에 보이는 썸네일을

가로 사이즈 비율로 줄이면서 세로는 크롭하고 싶은데요.

어찌 수정하면 될까요?

소스에 친절하게 설명되어 있는데도
제가 초보라 어떻게 건드려야 할지 난감하네요

부탁드립니다~

thumbnail의 if 로직입니다. 구조화 되지 않고 너무 많은 if를 써버렸습니다. ㅠ..ㅠ...

$width에 값이 있으면
- $height에 값이 있으면
- $width > 이미지크기
- $height > 이미지크기 : 이미지 크기대로 썸을 생성
- else
- $is_crop : 크롭
- else : 비율대로 썸을 생성
- else
$ratio로 $height를 구해서,
- $height > $tmp_y : 비율대로 썸 생성 (높이가 좀 부족 합니다) <-- 이부분에서 높이를 맞추고 넓기를 crop하자는 의견도 있어요
- else : 이미지 비율로 조정한 후 높이를 crop
- $height에 값이 없으면 (crop 하지 않습니다)
- $width가 이미지 크기보다 더 크면 : 이미지 크기대로 썸을 생성
- else : 비율대로 썸을 생성

$width에 값이 없으면 (높이로만 정렬하는 갤러리의 경우)
- $height가 이미지 크기보다 더 크면 : 이미지 크기대로 썸을 생성
- else
- $is_crop : crop
- else : 비율대로 썸을 생성
