raphael js setViewBox没有调整我的论文
问题描述：
我在raphael上遇到了setViewBox的问题，即使我做了 myPaper.setViewBox（0,0，new_map_width，new_map_height，true），也没有调整纸张大小; （JS代码第9行）
I have a problem with setViewBox on raphael, The paper isn't resized even if I did myPaper.setViewBox(0, 0, new_map_width, new_map_height,true); (Line 9 on the JS code)
Nb：new_map_width = 400且new_map_height = 300，地图为800 * 600
Nb : new_map_width = 400 and new_map_height=300 and the map is at 800*600
答
我找到了解决方案，我必须在绘制所有路径后执行我的setViewBox方法，并使用一些数学技能:)
I found the solution, I have to execute my setViewBox method after drawing all the paths, and use some math skills :)
var original_width = 777;
var original_height = 667;
var zoom_width = map_width/original_width;
var zoom_height = map_height/original_height;
if(zoom_width<=zoom_height)
zoom = zoom_width;
else
zoom = zoom_height;
rsr.setViewBox($("#"+map_name).offset().left, $("#"+map_name).offset().top, (map_width/zoom), (map_height/zoom));
