신청폼에 서명란을 넣어놨는데
사이즈를 키우니까 서명 이미지도 같이 커져서 그런데 혹시 캔바스사이즈만 키우고 이미지크기는 그대로 할 수 있는 방법이 있을까요?

사이즈를 고정하기 위해서 이부분을 수정한 것인가요?//$("#canvas").width(sizedWindowWidth); $("#canvas").width(100); $("#canvas").height(40);
동작되는 주소가 있으면 더 명확하겠지만. 대략 아래와 같이 하면 어떻게 동작될지 궁금하네요
//Set Canvas width var sizedWindowWidth = $(window).width(); if(sizedWindowWidth > 700) sizedWindowWidth = 200; else if(sizedWindowWidth > 400) sizedWindowWidth = 150; else sizedWindowWidth = 100; $("#canvas").width(sizedWindowWidth);
