字体

立即在浏览器中尝试使用字形观众！

实用程序和用于从字体文件中提取字形和元数据的CLI。

目前允许加载Truetype或Opentype字体或字体集合，并提取元数据和字形几何形状。

命令行界面允许提取黑白，灰度和签名的距离字段PNG渲染以及JSON Metadata。

在没有参数的情况下运行命令行接口以检查所有可用的选项。

通过NPX： npx @hlorenzi/font运行

安装以下： npm install @hlorenzi/font

命令行示例

 # Extracts all glyphs from "arial.ttf" into PNG and JSON files.
npx @hlorenzi/font arial.ttf -o " output/unicode_[unicode] "

# Set glyph range.
npx @hlorenzi/font arial.ttf -o " output/unicode_[unicode] " --glyphs= " u+30..u+39 "

# Set output mode.
npx @hlorenzi/font arial.ttf -o " output/unicode_[unicode] " --img-mode= " png-sdf " 

软件包示例

 import { FontCollection , GlyphRenderer } from "@hlorenzi/font"
import fs from "fs"

// Load font file.
const fontBuffer = fs . readFileSync ( "arial.ttf" )

// Load font collection and get first font.
const fontCollection = FontCollection . fromBytes ( fontBuffer )
const font = fontCollection . fonts [ 0 ]

// Find glyph for Unicode character "a" and get its geometry,
// simplifying each bézier curve into 100 line segments.
const glyphIndex = font . getGlyphIndexForUnicode ( "a" . charCodeAt ( 0 ) )
const glyphGeometry = font . getGlyphGeometry ( glyphIndex , 100 )

// Render into a black-and-white buffer with scale factor 1 EM = 30 pixels,
// then crop empty borders and print to the console.
const glyphImage = GlyphRenderer . render ( glyphGeometry , 30 ) . cropped ( )
console . log ( glyphImage . printToString ( ) )
