when I do .text() then PDFKIT shows this given text in a pdf . The code is given below :-
const doc = new PDFDocument();
// pipe the document to a blob
const stream = doc.pipe(blobStream());
// add your content to the document here, as usual
doc.fontSize(25).text(text, 100, 100);
// get a blob when you're done
doc.end();
But, I want to know the function which can take html code as arguement and render that html code on the pdf . Or suggest any other method but using PDFKIT module only.
pdfkit doesn't interpret HTML natively. There is another module that can parse simple HTML. It may do what you're looking for.

I am using TCPDF to generate a 2 page pdf document.
I have added a header and a footer to the document. The text part of the header and footer shows up correctly on each page however when I include an image logo in the header it is only showing up on the first page.
public function Header()
{
$this->Image('/home/xxxxxx/public_html/xxxxxxxx/uploads/logo/logo.png',10,6,0,13);
$this->SetFont('helvetica','B',20);
$this->Cell(80);
$this->Cell(0,0, $project->name . ' - Project Plan',$frame,0,'R');
$this->Ln(8);
$this->SetFont('helvetica','',10);
$this->Cell(0,0, $organisation->name,$frame,0,'R');
$this->Ln(10);
}
Does anyone have any idea what I am doing wrong here?
Thanks
I think is not related to header/footer, but I think TCPDF has bug that broken Image function with same image file loaded multiple times as reported here TCPDF - image displayed only once
bug also present on actual version tecnickcom/tcpdf:6.2.26
I resolve this problem by loading image outside and pass to the function as string.
public function Header()
{
$this->Image('#'.file_get_contents('/home/xxxxxx/public_html/xxxxxxxx/uploads/logo/logo.png'),10,6,0,13);
$this->SetFont('helvetica','B',20);
$this->Cell(80);
$this->Cell(0,0, $project->name . ' - Project Plan',$frame,0,'R');
$this->Ln(8);
$this->SetFont('helvetica','',10);
$this->Cell(0,0, $organisation->name,$frame,0,'R');
$this->Ln(10);
}
As said it is a tcpdf bug. In my case I had two logos in header one png and the other jpg. The problem happened only with the .png. Changing the image type from png to jpg solved the issue.
I solved this by using base64 encoded string like this:
$image = base64_encode(file_get_contents('path_to_image'));
Then you can use it like this:
<img src="#<?= $image ?>" />
Is it possible to include custom fonts in jsPDF ?
With the basic library, if I console log 'doc.getFontList()' I get:
Courier, Helvetica, Times, courier, helvetica, times
But, say I want to use 'Comic Sans' ( not that I would ;o) ) can it be done ?
Even better, could I use a font is locally stored and has been declared in the site with #font-face ?
I found this was possible by modifying jsPDF.js to expose the existing addFont method in the public API.
In jsPDF.js, look for:
//---------------------------------------
// Public API
Add the following:
API.addFont = function(postScriptName, fontName, fontStyle) {
addFont(postScriptName, fontName, fontStyle, 'StandardEncoding');
};
I put this method near other font methods for clarity - API.setFont, API.setFontSize, API.setFontType, etc.
Now in your code, use:
doc.addFont('ComicSansMS', 'Comic Sans', 'normal');
doc.setFont('Comic Sans');
doc.text(50,50,'Hello World');
This works for me with #font-face fonts included with css before loading jsPDF, as well as system fonts. There's probably a better way to do this using jsPDF's plugin framework, but this quick and dirty solution should at least get you going.
Note that doc.getFontList() will not show added fonts:
// TODO: iterate over fonts array or return copy of fontmap instead in case more are ever added.
It seems to be a lot easier with the latest version of jsPDF (1.5.3):
If you look in the folder jsPDF-master > fontconverter, there's a file fontconverter.html. Open in your browser and use the Browse... button to navigate to, and select your .ttf font file.
Click 'Create'.
The page will offer a "download" to be saved. This will produce a .js file called [something like] RopaSans-Regular-normal.js. This needs to be included in your page producing the PDF's. Personally, I've done it in the main page's header (and please note the order of the scripts):
<!-- pdf creation -->
<script src="FileSaver.js-master/src/FileSaver.js"></script>
<script src="jsPDF-master/dist/jspdf.debug.js"></script>
<!-- custom font definition -->
<script src="path-to-the-file-just-saved/RopaSans-Regular-normal.js" type="module"></script>
Now in your PDF generation method in js:
doc.setFont('RopaSans-Regular');
doc.setFontType('normal');
Here is the solution I'm using...
First, as others have mentioned - you need these two libraries:
jsPDF: https://github.com/MrRio/jsPDF
jsPDF-CustomFonts-support: https://github.com/sphilee/jsPDF-CustomFonts-support
Next - the second library requires that you provide it with at least one custom font in a file named default_vfs.js. I'm using two custom fonts - Arimo-Regular.ttf and Arimo-Bold.ttf - both from Google Fonts. So, my default_vfs.js file looks like this:
(
(function (jsPDFAPI) {
"use strict";
jsPDFAPI.addFileToVFS('Arimo-Regular.ttf','[Base64-encoded string of your font]');
jsPDFAPI.addFileToVFS('Arimo-Bold.ttf','[Base64-encoded string of your font]');
})(jsPDF.API);
Obviously, you version would look different, depending on the font(s) you're using.
There's a bunch of ways to get the Base64-encoded string for your font, but I used this: https://www.giftofspeed.com/base64-encoder/.
It lets you upload a font .ttf file, and it'll give you the Base64 string that you can paste into default_vfs.js.
You can see what the actual file looks like, with my fonts, here: https://cdn.rawgit.com/stuehler/jsPDF-CustomFonts-support/master/dist/default_vfs.js
So, once your fonts are stored in that file, your HTML should look like this:
<script src="js/jspdf.min.js"></script>
<script src="js/jspdf.customfonts.min.js"></script>
<script src="js/default_vfs.js"></script>
Finally, your JavaScript code looks something like this:
const doc = new jsPDF({
unit: 'pt',
orientation: 'p',
lineHeight: 1.2
});
doc.addFont("Arimo-Regular.ttf", "Arimo", "normal");
doc.addFont("Arimo-Bold.ttf", "Arimo", "bold");
doc.setFont("Arimo");
doc.setFontType("normal");
doc.setFontSize(28);
doc.text("Hello, World!", 100, 100);
doc.setFontType("bold");
doc.text("Hello, BOLD World!", 100, 150);
doc.save("customFonts.pdf");
This is probably obvious to most, but in that addFont() method, the three parameters are:
The font's name you used in the addFileToVFS() function in the default_vfs.js file
The font's name you use in the setFont() function in your JavaScript
The font's style you use in the setFontType() function in your JavaScript
You can see this working here: https://codepen.io/stuehler/pen/pZMdKo
Hope this works as well for you as it did for me.
I'm using Angular 8 and Todd's answer worked for me.
Once you get the .js file from fontconverter.html, you can import it in typescript like so:
import fontref = require('path/to/font/CustomFont-normal.js')
Then all you have to do to load the font is 'call' fontref:
makePdf() {
let doc = new jsPDF();
fontref; // 'call' .js to load font
doc.getFontList(); // contains a key-value pair for CustomFont
doc.setFont("CustomFont"); // set font
doc.setFontType("normal");
doc.setFontSize(28);
doc.text("Hello", 20, 20);
window.open(doc.output('bloburl')); // open pdf in new tab
}
After looking at the fontconverter.html, and seeing that it does nothing more than package the TTF files into a base64 string inside a JS file, I came up with the following method that I call before creating my document. It basically does what the individual files resulting from fontconverter.html do, just on-demand:
async function loadFont(src, name, style, weight) {
const fontBytes = await fetch(src).then(res => res.arrayBuffer());
var filename = src.split('\\').pop().split('/').pop();
var base64String = btoa(String.fromCharCode.apply(null, new Uint8Array(fontBytes)));
var callAddFont = function () {
this.addFileToVFS(filename, base64String);
this.addFont(filename, name, style, weight );
};
jsPDF.API.events.push(['addFonts', callAddFont]);
}
Call it like this:
await loadFont("/css/fonts/exo-2-v9-latin-ext_latin-italic.ttf", "Exo-2", "italic", 400);
await loadFont("/css/fonts/exo-2-v9-latin-ext_latin-regular.ttf", "Exo-2", "normal", 400);
await loadFont("/css/fonts/exo-2-v9-latin-ext_latin-500.ttf", "Exo-2", "normal", 500);
await loadFont("/css/fonts/exo-2-v9-latin-ext_latin-500italic.ttf", "Exo-2", "italic", 500);
It loads the font from the URL, and adds it to the VFS and font manager. Important: the font name cannot include spaces. You won't get any warnings, but the resulting PDF will either not open or the text will look funny.
Some of these answers are outdated, so I am linking the readme file from Mr. Rio himself regarding the latest release as of this post. Below is a copy of the paragraph from that readme file followed by a link to the readme file itself. Hope this additional resource is helpful:
Use of UTF-8 / TTF:
The 14 standard fonts in PDF are limited to the
ASCII-codepage. If you want to use UTF-8 you have to to integrate a
custom font, which provides the needed glyphs. jsPDF supports
.ttf-files. So if you want to have for example chinese text in your
pdf, your font has to have the necessary chinese glyphs. So check if
your font supports the wanted glyphs or else it will show a blank
space instead of the text.
To add the font to jsPDF use our fontconverter in
/fontconverter/fontconverter.html . The fontconverter will create a
js-file with the content of the provided ttf-file as base64 encoded
string and additional code for jsPDF. You just have to add this
generated js-File to your project. You are then ready to go to use
setFont-method in your code and write your UTF-8 encoded text.
https://github.com/MrRio/jsPDF/blob/master/README.md#use-of-utf-8--ttf
//use necessary config, read the docs http://raw.githack.com/MrRio/jsPDF/master/docs/jsPDF.html
import MuliSemiB64 from "../functions/MuliSemiB64";
let doc = new jsPDF({
orientation: "p",
unit: "px",
format: "a5",
});
doc.addFileToVFS("MULI-SEMIBOLD.TTF", MuliSemiB64());
//MuliSemiB64() is a function that returns the Muli ttf file in its base64 string format, convert your font ttf file and copy the string, save to a variable and use the function to return the string. Use a site like https://www.giftofspeed.com/base64-encoder/ for the conversion
doc.addFont("MULI-SEMIBOLD.TTF", "Muli-Semi-Bold", "Semi-Bold");
doc.setFont("Muli-Semi-Bold", "Semi-Bold");
doc.text("Have Fun :*", 35, 25);
The easiest way that I have found by far is using the jspdf-customfonts package.
Simply install the package by
npm i jspdf-customfonts
then add the following files in the head tag of your index.html for default configurations
script src="https://unpkg.com/jspdf#latest/dist/jspdf.min.js"></script>
<script src="dist/jspdf.customfonts.min.js"></script>
<script src="dist/default_vfs.js"></script>
Now you can download the ttf file of whichever font you want. Then go to this site, select your font and copy the code, and you are done!
I am using the OBJLoader to load a large 3D model (described in a .obj file) and I want to display the models name on its surfaces. Though it seems that Three.js can only display English characters. My question is how can I display Chinese characters in Three.js?
there are a couple of ways to display text (https://github.com/mrdoob/three.js/wiki/Text-in-Three.js), but since exporting a chinese font might be more difficult, it might be easier to draw the chinese characters to a canvas texture and use the texture as a material in the scene.
It seem that you can use Facetype.js to get a Chinese font library, for example"YaHei_Regular.typeface.json" , then you can show Chinese characters.
var fontLoader = new THREE.FontLoader();
fontLoader.load("YaHei_Regular.typeface.json", (font)=> {
this.font = font;
});
Another option is using msdf-bmfont-xml. This example uses Microsoft YaHei.
charset.txt —
你好，世界
You may need to install dependencies first. Then:
npm install msdf-bmfont-xml -g
msdf-bmfont -f json yahei.ttf -i charset.txt --pot --square
and finally, use three-bmfont-text to render the text.
Three.js doesn't display Chinese regularly because it doesn't support the charset. You have to load it dynamically.
It seems there're two methods to load: 1, new THREE.TTFLoader().load('*.ttf') , it loads a ttf file that support Chinese charset. But I failed.
2, new THREE.FontLoader().load('*.json') it loads a json file transformed by
the ttf on http://gero3.github.io/facetype.js/ website.
But firstly you have to find a complete ttf file. I tried 方正兰亭超细黑简体 and 方正赵佶瘦金书 which both work, you can google and download ttf file. I found some ttf can't be identified by three.js completely. You perhaps see some Chinese char display normally but others still display '?'.
The final code snippets as following:
const three_font = new THREE.FontLoader();
three_font.load('*.json', function (font_font) {
font=font_font
})
// finally add text with font
const geometry = new THREE.TextGeometry(
{
font: font,
size, height: h, curveSegments: 4, bevelThickness: 2, bevelSize: 2, bevelEnabled: true
});
geometry.computeBoundingSphere();
geometry.computeVertexNormals();
const mesh = new THREE.Mesh(geometry, pool.textMaterial);
mesh.position.set(x * deviation, y, z * deviation);
mesh.rotation.set(rx, ry, rz);
scene.add(mesh);
When I paste a URL into a TinyMCE editor it converts the text into a link.
So http://vimeo.com/18150336 would be come http://vimeo.com/18150336. I would like to keep the plain text. Is their a way to configure TinyMCE to keep the link as plain text.
I do not want to strip out tags as adding a hyperlinks should be an option on the toolbar. It should just not happen by default.
You can use the paste plugin and the setting paste_preprocessing in order to keep the plain text. You might need to check inside the function specified using paste_preprocessing if you got a link or not.
It's been 5 years, So I'm probably using a newer version of TinyMCE, anyway this solution worked for me, Just add this option:
paste_preprocess: function(plugin, args) {
args.content += ' ';
}
So when you initialize the tinymce, it should be something like this:
tinymce.init({
selector: "textarea", // change this value according to your HTML
plugins: "paste",
paste_preprocess: function(plugin, args) {
args.content += ' ';
}
});
This is the page of documentation for TinyMCE V4
It is the TinyMCE plugin autolink which is responsible for automatically creating links on paste. (And write).
