推荐答案

你是什么意思a像素？

像素是图形元素。字符串是一个字符数组。这些有什么共同之处？这就像问一磅黄油的重量华氏度。 ： - ）

What do you mean by a "pixel"?

A pixel is graphics element. A string is an array of characters. What do these have in common? It''s like asking how much a pound of butter weighs in degrees Fahrenheit. :-)

我的意思是连接该字符串两端的最低直线将包含多少像素。我想计算一下。

I mean that the lowest straight line joining the two ends of that string will contain how many pixels. I want to calculate that.

你想用哪种字体？

点大小是多少？

什么是字形布局？

怎么样的字距调整？

等......

Which font do you want to use?
What is the point size?
What is the glyph layout?
What about kerning?
etc...
