Documentation

Instructions

GetStarted

npm i hummus-recipe --save

Coordinate System

In order to make things easier, I use Left-Top as center [0,0] instead of Left-Bottom. You may write and edit the pdf like you write things on papers from the left top corner. It is similar to the Html Canvas

pdfDoc
    .text('start from here', 0, 0)
    .text('next line', 0, 20)
    .text('some other texts', 100, 100)
    ...

Create a new PDF

const HummusRecipe = require('hummus-recipe');
const pdfDoc = new HummusRecipe('new', 'output.pdf',{
    version: 1.6,
    author: 'John Doe',
    title: 'Hummus Recipe',
    subject: 'A brand new PDF'
});

pdfDoc
    .createPage('letter-size')
    .endPage()
    .endPDF();
const HummusRecipe = require('hummus-recipe');
const pdfDoc = new HummusRecipe('new', 'output.pdf');
pdfDoc
    // 1st Page
    .createPage('letter-size')
    .circle('center', 100, 30, { stroke: '#3b7721', fill: '#eee000' })
    .polygon([ [50, 250], [100, 200], [512, 200], [562, 250], [512, 300], [100, 300], [50, 250] ], {
        color: [153, 143, 32],
        stroke: [0, 0, 140],
        fill: [153, 143, 32],
        lineWidth: 5
    })
    .rectangle(240, 400, 50, 50, {
        stroke: '#3b7721',
        fill: '#eee000',
        lineWidth: 6,
        opacity: 0.3
    })
    .moveTo(200, 600)
    .lineTo('center', 650)
    .lineTo(412, 600)
    .text('Welcome to Hummus-Recipe', 'center', 250, {

        fontSize: 30,
        bold: true,

    .text('some text box', 450, 400, {
