【问题描述】:
利基编程问题:我正在通过字节制作来开发 OpenType 字体(而不是使用 Fontlab 或 FontForge 等设计工具),现在有一个自定义 OpenType-CFF 字体,它实现了基本拉丁语 unicode 块的子集(特别是它实现了 .notdef 和波浪号)。
CFF 块通过tx -3 验证(http://www.adobe.com/devnet/opentype/afdko.html),整个字体通过TTX(https://github.com/behdad/fonttools)和微软的“字体验证器”(http://www.microsoft.com/typography/FontValidator.mspx ) 不会报告字体中的任何错误。将其作为自定义 webfont 加载(在支持 otf 的浏览器中作为纯 otf,在不支持 otf 的浏览器中包装为 WOFF)正确设置实现字形的样式。
然而,即使有这么明显的正确性,windows 字体预览器仍报告它不是一个有效的字体文件,window 不会让我安装它。我一直在寻找有关 Windows 需要什么字体才能安装字体的信息,但互联网似乎充满了如何以用户身份使用字体,而不是作为开发人员需要满足哪些要求。
我不太确定包含此问题的代码的最佳方法是什么,因为它不是很传统的编程;生成器代码是用 JavaScript 编写的,但该代码工作得非常好,并为所有意图和目的生成了一个(保存一个)正确的字体。
如果您知道如何使用十六进制编辑器,那么以下是字体的十六进制字符串:

如果有任何其他工具可用于确定字体是否“完成”到可以安装的程度,或者如果有人知道说明字体在安装之前需要满足哪些标准的文档,该信息非常受欢迎。当然,如果有人碰巧知道我的字体代码仍然缺少什么(作为字节码或 TTX XML),或者他们看到奇怪/错误的位,我也对您的 cmets/answers 非常感兴趣。
【问题讨论】:
-
当我看到标题时,我确信这会离题,但你说服我不是。
-
好问题。您可能还想反转内部轮廓的方向。
-
好观察!虽然 TTF 和 CFF 的剪切方向规则不同,但事实证明 android 只是假设 TTF 规则并显示出一个实心矩形;反转使其正确显示切口 =)
-
事实证明,问题在于
name表中缺少两条记录。如果 NameID 3 和 6 的记录丢失,则没有骰子。 Windows 不会预览它,更不用说安装它了。奇怪的是,NameID 4 和 5 的记录——尽管代表了完整的字体名称和版本——与安装目的无关。
