如何使用iText在PDF中嵌入Helvetica字体?

itext fonts pdf

Juha Syrjälä · 技术社区 · 16 年前

以下操作不起作用:

BaseFont helvetica = BaseFont.createFont(BaseFont.HELVETICA,
        BaseFont.CP1252, BaseFont.EMBEDDED);
Font font = new Font(helvetica, 20, Font.BOLD);

也就是说,这将返回false:

font.getBaseFont().isEmbedded()

如果我自己将TrueType文件作为参数提供给createFont()方法,则嵌入可以工作。

是的,嵌入已定义字体将不起作用。
它不能工作。

我对源代码做了一些深入的研究,似乎iText显式地忽略了这一点 BaseFont.EMBEDDED 特定字体的标志,Helvetica就是其中之一。

如果您为Helvetica提供字体文件(例如TrueType.ttf),则嵌入可能有效。
