推荐答案
我找到了第四个问题的答案-边界框是否应该紧密贴合".
I found the answer to the 4th question - "Should the bounding boxes fit snugly".
似乎尽可能地拟合矩形会带来更好的结果.
It seems that fitting the rectangles as much as possible gives much better results.
对于其他12个点和300 dpi，就足够了，如@Yaroslav所建议的那样.我认为最好关闭抗锯齿功能.
For the other 12 pts and 300 dpi will be good enough, as @Yaroslav suggested. I think anti-aliasing is better turned off.
