<div>New:</div>
<div>- In version 2.1 (February 26 2007) Tom Bishop has done some important speed enhancements.</div>
<div>- From version 2 (July 17 2006) the script uses the imageconvolution function in PHP</div>
<div>version >= 5.1, which improves the performance considerably.</div>
<div>
</div>
<div>
</div>
<div>Unsharp masking is a traditional darkroom technique that has proven very suitable for</div>
<div>digital imaging. The principle of unsharp masking is to create a blurred copy of the image</div>
<div>and compare it to the underlying original. The difference in colour values</div>
<div>between the two images is greatest for the pixels near sharp edges. When this</div>
<div>difference is subtracted from the original image, the edges will be</div>
<div>accentuated.</div>
<div>
</div>
<div>The Amount parameter simply says how much of the effect you want. 100 is 'normal'.</div>
<div>Radius is the radius of the blurring circle of the mask. 'Threshold' is the least</div>
<div>difference in colour values that is allowed between the original and the mask. In practice</div>
<div>this means that low-contrast areas of the picture are left unrendered whereas edges</div>
<div>are treated normally. This is good for pictures of e.g. skin or blue skies.</div>
<div>
</div>
<div>Any suggenstions for improvement of the algorithm, expecially regarding the speed</div>
<div>and the roundoff errors in the Gaussian blur process, are welcome.</div>

<div>그누5에 기본으로 썸네일엔진이 들어가있는데 사용해보니 너무 좋은것같아서 혹시 그누4에 적용시킬 방법이 없을까해서 질문드립니다.
썸네일만 생성하면되기에 전체는 필요없을듯하고 상단코드만 사용하면 될것같이 보이는데 어떻게 수정해줘야할지 전혀 모르겠네요..ㅠㅠ
도움 부탁드려요~

스킨파일 참고하시면 될것 같습니다. 우선 상단에 아래처럼 파일불러오고
include_once(G5_LIB_PATH.'/thumbnail.lib.php');
이렇게 사용하던가
get_view_thumbnail($view['file'][$i]['view']);
이렇게 사용하면 될것 같습니다.
get_list_thumbnail($board['bo_table'], $list[$i]['wr_id'], 가로크기, 세로크기);
앗! 그전에 thumbnail.lib.php 파일을 열어 그누4 변수로 바꿔줘야겠네요
