Java：以像素为单位获取具有特定高度的字体 [英] Java: Getting a font with a specific height in pixels

问题描述

使用 FontMetrics 可以很容易地确定字体的渲染高度，但是相反呢？我怎样才能获得一个字体，适合像素的特定高度？

lockquote
给我 Verdana




$ b

如何向Java请求这个？

解决方案Jen，

我不认为有直接的方式来找到一个字体的高度;只是一种间接的方式...通过循环遍历尺寸，并测试每个的高度是<=所需的高度。

如果你这样做了一次，只需循环浏览它们...如果你正在做即时，那么做二进制搜索，它会快点。

干杯。基思。

It’s easy to determine the rendered height of a font using FontMetrics, but what about the other way around? How can I obtain a font that will fit into a specific height in pixels?

"Give me Verdana in a size that is 30 pixels high from ascender to descender."

How do I ask Java for this?

解决方案

Jen,

I don't think there's a "direct" way to find a font by height; only an indirect way... by looping through the sizes, and testing the height of each is <= required height.

If you're doing this once, just loop through them... if you've doing it "on the fly" then do a binary search, it'll be quicker.

Cheers. Keith.
