@Gregwar zongmi's problem is $builder->setBackgroundColor(0,0,0); not working. @zongmi you need call $builder->setBackgroundColor(0,0,0) before $builder->build(215,80) because build means this image is builded,after the image is builded,change the backgroundcolor make no sence(必须在build之前setColor,图片都build出来了再set没有意义)
