JavaFX字体派生粗体 [英] Javafx font derive bold

问题描述

我想为我的javafx应用程序动态更改(加载的)文本字体，所以我执行了以下代码:

I wanted to change a (loaded) text font dinamically for my javafx application, so I did this code:

Font font = Font.loadFont(Fonts.class.getClassLoader().getResource("path/font.woff").toExternalForm(), 25);
Font bold = Font.font(font.getFamily(), FontWeight.BOLD, font.getSize());
Font italic = Font.font(font.getFamily(), FontPosture.ITALIC, font.getSize());
Font boldItalic = Font.font(font.getFamily(), FontWeight.BOLD, FontPosture.ITALIC, font.getSize());

但是当我尝试将文本字体更改为粗体或斜体时，没有任何变化，并且我似乎没有找到像java.awt.Font#deriveFont中那样的方法，您可以从另一种字体派生斜体或粗体.
应用字体的代码:

but when I try to change the text font to bold or italic nothing changes, and I don't seem to locate some method like the one in java.awt.Font#deriveFont where you could derive italic or bold from another font.
Code to apply the font:

public void applyFont(javafx.scene.text.Text text) {
    text.setFont(font);
}

更多日志:
我放了一些日志，说他得到了什么字体，并打印了Font#toString()结果:

More log:
I put some log that says what font is he getting and prints the Font#toString() result:

getFont(bold=false, italic=false) -> Font[name=<Name> Regular, family=<Name>, style=Regular, size=25.0]
getFont(bold=true, italic=false) -> Font[name=<Name> Regular, family=<Name>, style=Regular, size=25.0]
getFont(bold=false, italic=true) -> Font[name=<Name> Regular, family=<Name>, style=Regular, size=25.0]
getFont(bold=true, italic=true) -> Font[name=<Name> Regular, family=<Name>, style=Regular, size=25.0]

但是如果我将字体加载中的第一行代码替换为

But if I replace the first line of code in the font loading with

font = Font.font(null, 25);//get the system's default font

它有效，我得到以下输出:

It works and I get this output:

getFont(bold=false, italic=false) -> Font[name=System Regular, family=System, style=Regular, size=25.0]
getFont(bold=true, italic=false) -> Font[name=System Bold, family=System, style=Bold, size=25.0]
getFont(bold=false, italic=true) -> Font[name=System Italic, family=System, style=Italic, size=25.0]
getFont(bold=true, italic=true) -> Font[name=System Bold Italic, family=System, style=Bold Italic, size=25.0]

推荐答案

您需要加载另一个字体文件，该文件将提供适当的姿势或权重.

You need to load another font file, that will provide appropriate Posture or Weight.

对于每种流行字体(包括系统，当您调用Font.font(null, 25)时，都会使用该字体)，系统中都有几个字体文件:一个用于常规，一个用于斜体，一个用于粗体等.

For every popular font (including System, that is used, when you call Font.font(null, 25)) there are several font files in the system: one for regular, one for italic, one for bold etc.

例如，对于Times New Roman，我的字体文件夹中有四个文件:

For instance, for Times New Roman there are four files in my Fonts folder:

• Times New Roman Bold Italic.ttf
• Times New Roman Bold.ttf
• Times New Roman Italic.ttf
• Times New Roman.ttf
