一，直接用ImageMagick把svg转为png时有瑕疵
1,例子:原图:
转换命令:
liuhongdi@lhdpc:/data/work/tmpimg$ convert go-logo-blue.svg go.png效果如下:
转换完后图片不完整
2，查看convert是否调用rsvg-convert
确实调用了,但不确定为什么会出现此情况
liuhongdi@lhdpc:/data/work/tmpimg$ convert -list delegate | grep 'svg ='
svg => "rsvg-convert' -o '%o' '%i"二，直接使用rsvg-convert命令:
liuhongdi@lhdpc:/data/work/tmpimg$ rsvg-convert -w 1200 go-logo-blue.svg -o go1200.png效果:
