使用 .text() 方法的 jsPDF 中的字母间距

Question

How do I specify letter spacing to text in jsPDF .text() method? This is the code I use now.

var doc = new jsPDF('p', 'mm', [183, 203]);
doc.setFontSize(9);
doc.setFont("monospace");
doc.text(39, 38, 'hello world');
doc.output('dataurl');

Answer 1

Taken from jspdf.js , you can use lstext function to specify letter spacing.

API.lstext = function (text, x, y, spacing) {
    for (var i = 0, len = text.length; i < len; i++, x += spacing) this.text(text[i], x, y);
};

Usage should be,

doc.lstext('Hello World', 39, 38, 5);

Answer 2

this will change the letter spacing of the entire pdf pdf.setCharSpace(5); 5 is the space that you give to the entire pdf, if you want to apply it only to a specific text it would be pdf.text('text', 30, 105, { charSpace: 5 });
