v0.6.0

• Add methods to measure width and height of text strings in both standard and embedded fonts.
  • #58

  • #58
• PDFDocument.embedFont is now deprecated. Please use PDFDocument.embedNonstandardFont instead.
• When drawing text (with the drawText() or drawLinesOfText() operators, for example), please be sure to use the font.encodeText() method for the font you are using. This is highly recommended for both standard and nonstandard fonts (and is required if you want to use characters outside the ascii range).
• The following examples demonstrate usage of the new font.widthOfTextAtSize() and font.heightOfFontAtSize() methods to measure text, as well as usage of the font.encodeText() method to encode characters outside the ascii range.

  • pdf-lib/lib/x/y/z is the CommonJS module.
  • pdf-lib/es/x/y/z is the ES6 module.
  • pdf-lib now directly exports all public classes and functions. For example:

    // v0.1.0
    import { PDFDocumentWriter, PDFDocumentFactory } from 'pdf-lib/core/pdf-document';
    import { drawText } from 'pdf-lib/helpers/pdf-operators/composite';
  
    // Now
    import {
      PDFDocumentWriter,
      PDFDocumentFactory,
      drawText,
    } from 'pdf-lib';
