Add Image In Header Using Html-pdf Node Module
Answer :
It is possible to add the image in options header. 1.Load the image in html body with "display:none" style. 2.Then add the image in the options header By doing this the image is cached and can attach the image in header.
var options = { "format": 'Letter', "orientation": "portrait", "header": { "contents": "<img src='image path' />", "height": "30mm" }, "footer": { "contents": footer } } pdf.create("<div style='display:none'><img src='image path' /></div>", options).toFile("sample.pdf", function(err, res) { if (err) { console.error(err); callback(); } });
Refering to this issue on the github, you can't put your image directly in options.header
, you have to put it in the body inside a <div id="pageHeader"></div>
:
var pdf = require('html-pdf'); var path = require('path'); // this is very important, you have to put file:// before your path // and normalize the resulting path var imgSrc = 'file://' + __dirname + '/350x120.png'; imgSrc = path.normalize(imgSrc); // or var imgSrc = path.join('file://', __dirname, '/350x120.png'); // Options var options = { "header": { "height": "45mm", "contents": "" }, "footer": { "height": "28mm", "contents": "<span style='color: #444;'>{{page}}</span>/<span>{{pages}}</span>" } } // put your entire header here and the content of the page outside the <div id="pageHeader"></div> var result = "<div id='pageHeader'><img src='" + imgSrc + "' /><div style='text-align: center;'>Author: Marc Bachmann</div></div>"; result += "<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>"; var fileName = __dirname + '/test.pdf'; pdf.create(result, options).toFile(fileName, function(err, res) { if (err) { console.error(err); } });
With this code, I get this pdf:
