I'm using the GNU texinfo package to generate both PDF and .info files from a .texi file.
I'm trying to update an old .texi file (not changed since 2001) and generate the same PDF output. I've resolved a number of issues, but there are a couple outstanding. In the old PDF, the title was in Helvetica and body text is Liberation Serif. In the new PDF, both are Computer Modern.
I've read everything that I can find about fonts, but I'm not able to change the fonts. Nothing that I do seems to work. Everything I have tried generates errors.
In my .texi file, before any \setfont directives, I have \def\fontprefix{uh} which, if I read the pdftex.map file correctly, should select the NimbusSanL font set (e.g. uhvr8a.pfb). I get the following errors:
mktexnam: Could not map source abbreviation for uhss10.
kpathsea: Running mktexmf uhss10
! I can't find file uhss10'.
<*> ...ljfour; mag:=1; ; nonstopmode; input uhss10`
Does anyone have a example .texi file which sets the font family to use? Or an explanation of what I'm doing wrong?
We are using Webfont Loader to load google fonts. And inside the active callback of WebFont.load we load our main script and bootstrap angular.js application.
<script type="text/javascript">
WebFontConfig = {
google: {
families: ['Open Sans:400,700,700i,400i:latin-ext']
},
active: function() {
var mainScript = document.createElement('script');
mainScript.src = "/js/main.js";
mainScript.onload = function() {
angular.bootstrap(document, ['cob']);
}
document.body.appendChild(mainScript);
}
};
WebFont.load(WebFontConfig);
</script>
To make browser use default fonts until the google font file loaded, we set fonts for .wf-active class
html.wf-active {
font-family: 'Open Sans', sans-serif;
}
Inside angular run, we switch apploaded and clear screen from loaders and show the application.
angular.module('mymodule')
.run([function() {
$rootScope.appLoaded = true;
}
]);
html
<body>
<div class="app-loader" ng-hide="appLoaded">loading...</div>
<div class="page-container" ng-if="appLoaded">
application loaded. <button>GİRİŞ</button>
</div>
</body>
We see "loading..." until the font files loaded, then application bootstraps successfully.
But the button text is rendered as "G R " for a couple of seconds, after a while 'İ' and 'Ş' characters are loaded into screen and we see GİRİŞ on button.
I am sure the font file is loaded before application bootstraps, because the font doesn't change after the application is loaded.
May be irrelevant but, I got some image files on the page and foreign characters are rendered with the image files. So there is some kind of a wierd screen render latency.
We only have this issue on iOS application, I have tested it on iPhone 6 and 6s, and on xcode simulators.
This works as intended on browsers (safari, chrome and firefox) and on android application we create with the same cordova project.
After trying various preload methods, just as I was considering to give it up, I came accross to a fact here
most browsers download fonts when they're used in a page rather than
when they're declared in CSS.
It seems like latin-ext subset of the font is delayed until it is used inside the page.
I have solved the issue by putting a dummy character (İ) that will make it download latin-ext subset on load screen
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 just downloaded a fresh copy of tinymce, uploaded it and tried to use it on my UTF-8 encoded website.
The menu bar icons are either garbage because it can't find it's presentation file (font?) or the encoding of one of the 10000 files is wrong.
Anyone knowing this bug? I didn't change anything, just uploaded..
TinyMCE doesn't use my german lang file either, obviously. I placed the js file into the "langs" folder.
<script type="text/javascript">
tinyMCE.baseURL = '//example.com/de/assets/scripts/tinymce';
tinyMCE.suffix = '.min';
tinymce.init({
selector: "textarea"
});
</script>
Do I have to set any configuration for path, basepath, ... ??
My actual path to tinymce is scripts/tinymce/tinymce.min.js. The origin path provided by the shipped package was tinymce/tinymce/js/tinymce/tinymce.min.js but honestly this kind of nesting folders without any reason..
update: The paths are working, it does read files not directly linked.. (like theme.min.js) successfully.
I am using Html2PDf to convert html to pdf.
But I am not able to achieve that it shows local (latvian) language letters. It shows ? instead.
I do understand that I should somehow add appropriate fonts, but I do not know where to get those fonts (which one support latvinan language) and how to add them into html2pdf.
Html2Pdf is based on tcpdf and currently there is font folder.
I think that is seems trivial question, but I was searching via google, but have not found answer that works for me.
require_once('inc/html2pdf/html2pdf.class.php');
$html2pdf = new HTML2PDF('P','A4','en');
//$html2pdf->pdf->setDefaultFont('times');
// HEADER
$pdf_output .='<page style="font-size: 11px; >';
$pdf_output .= '<img src="images/raka_pdf_logo.png" alt="logo"/><br><br><br><br>';
...
You may find the right font-family in html2pdf>tcpdf>fonts
