| ```js | ||
| var TTFFont = require('ttfjs') | ||
| ``` | ||
| ### new TTFFont(buffer) | ||
| Create a new font instance from the provided buffer (can be a Node `Buffer` or an `ArrayBuffer`). | ||
| #### .stringWidth(str, size) | ||
| Returns the width for the given string in the given font size. | ||
| #### .lineHeight(size, [includeGap]) | ||
| Returns the line height for the given font size with line gap or without. | ||
| #### .lineDescent(size) | ||
| Return the line descent for the given font size. | ||
| #### .clone() | ||
| Returns a clone of the font object. | ||
| #### .save() | ||
| Encodes the font into an `ArrayBuffer`. | ||
| #### .subset([opts]) | ||
| Creates a `Subset` for the current font. | ||
| ### .subset([opts]) | new TTFFont.Subset(font, [opts]) | ||
| Creates a `Subset` for the current font. | ||
| **Options:** | ||
| - **remap** - (default: true) whether to remap char codes | ||
| - **trimNames** - (default: false) whether trim localized names (reduces file size) | ||
| #### .use(chars) | ||
| Add the given characters to the subset. | ||
| #### .encode(str) | ||
| Encode the given string using the current remapping. | ||
| #### .embed() | ||
| Embed the current used characters. | ||
| #### .save() | ||
| Encodes the subset into an `ArrayBuffer`. | ||
| ## Example | ||
| ```js | ||
| var fs = require('fs') | ||
| var TTFFont = require('ttfjs') | ||
| var font = new TTFFont(fs.readFileSync(__dirname + '/Corbel.ttf')) | ||
| var subset = font.subset() | ||
| subset.use('abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ 1234567890') | ||
| console.log(subset.encode('abcdefghijklmnopqrstuvwxyz')) | ||
| subset.embed() | ||
| fs.writeFileSync('./test.ttf', toBuffer(subset.save()), { encoding: 'binary' }) | ||
| function toBuffer(ab) { | ||
| var buffer = new Buffer(ab.byteLength) | ||
| var view = new Uint8Array(ab) | ||
| for (var i = 0; i < buffer.length; ++i) { | ||
| buffer[i] = view[i] | ||
| } | ||
| return buffer | ||
| } | ||
