jsPDF helper function: Convert points to other units

jsPDF_convert_points_to_other_units.js

function convertPointsToUnit(points, unit) {
  // Unit table from https://github.com/MrRio/jsPDF/blob/ddbfc0f0250ca908f8061a72fa057116b7613e78/jspdf.js#L791
  var multiplier;
  switch(unit) {
    case 'pt':  multiplier = 1;          break;
    case 'mm':  multiplier = 72 / 25.4;  break;
    case 'cm':  multiplier = 72 / 2.54;  break;
    case 'in':  multiplier = 72;         break;
    case 'px':  multiplier = 96 / 72;    break;
    case 'pc':  multiplier = 12;         break;
    case 'em':  multiplier = 12;         break;
    case 'ex':  multiplier = 6;
    default:
      throw ('Invalid unit: ' + unit);
  }
  return points * multiplier;
}

你这写反了吧，应该是 convertUnitToPoints 吧。
