什么是 PFB 二进制字体格式？
Adobe 的 PostScript Type 1 轮廓字体的二进制容器。

它是什么?
PFB 是 Printer Font Binary 的缩写,是由 Adobe Systems 公司创建的二进制文件格式,用于存储 PostScript Type 1 轮廓字体。Type 1 字体由 Adobe 作为 PostScript 页面描述语言的一部分推出,并在 1985 年随 Apple LaserWriter 得到广泛应用。
PFB 文件是围绕本应出现在 ASCII PFA 文件中的数据的紧凑包装器。它被组织成一系列段,每个段标记为 ASCII 文本或二进制格式,其中二进制部分(包括加密的 charstring 轮廓)作为原始字节而非十六进制文本存储。这使 PFB 文件的大小大约是相应 PFA 文件大小的一半。在 Windows 上,PFB 与 PFM 指标文件配对使用。
技术规格
优缺点
Advantages
Storing the binary section as raw bytes makes a PFB about half the size of the equivalent ASCII PFA file.
Type 1 fonts use cubic Bezier curves and hinting for crisp rendering, especially in print.
As the foundation of professional PostScript printing, Type 1 fonts were a print and publishing standard for decades.
Long supported across major operating systems and PostScript devices.
Disadvantages
Adobe ended authoring and support for Type 1 fonts in its applications in January 2023, encouraging migration to OpenType.
Type 1 fonts typically hold far fewer glyphs than modern OpenType fonts and lack advanced typographic features.
On some platforms a font requires separate outline and metrics files, complicating management.
何时使用
PFB 主要出现在旧版印刷和字体存档环境中。
遗留打印工作流程
Older professional publishing and prepress systems relied on PostScript Type 1 fonts in PFB form.
字体转换
PFB files are converted to OpenType or other modern formats to keep older typefaces usable.
数字保存
Archives retain PFB fonts to reproduce historical documents and designs accurately.
How to open a PFB file
PFB files, representing the PostScript Type 1 Binary Font Format, can be managed through various software categories, including professional tools, free/open-source options, browser-based solutions, and built-in operating system utilities. Professional software typically offers advanced features for font design and editing, making it suitable for graphic designers and typographers.
Free and open-source tools cater to users who need basic functionality without financial investment, while browser-based solutions provide accessibility without installation. Built-in utilities may offer limited capabilities for quick viewing or conversion.
When selecting software for PFB files, key decision factors include feature fidelity, the distinction between editing and viewing capabilities, cost models, and platform compatibility. Users should consider whether they need to edit fonts or simply view them, as this will influence the choice of software.
Export needs are also crucial, as some applications may only allow saving in specific formats, while others offer broader compatibility. In some cases, converting PFB files to more widely supported formats may be a better option for users not needing extensive editing features.
