linux:svg转png(rsvg-convert 2.50.7/ubuntu 21.10)

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:
