Fixes #82, #168, #171. This patch removes the artificial `SVGFont` class as well as the `SVGText::setFont(SVGFont $font)` method. Instead, it is now possible to register TrueType (`.ttf`) font files by calling `SVG::addFont()` with a file path. A TrueType font file parser is implemented based on Microsoft's OpenType specification. This allows us to choose the best matching font file for a given text element automatically, just like a browser would, based on algorithms from CSS. Currently, TTF files are supported in the "Regular", "Bold", "Italic", and "Bold Italic" variants. The simple algorithm implemented here tries to match the font family exactly, if possible, falling back to any other font. Generic font families such as "serif" or "monospace" aren't supported yet and will trigger the fallback. Also, the relative weights "bolder" and "lighter" aren't computed and fall back to normal weight. BREAKING CHANGE: `SVGFont` class and some methods on `SVGText` removed.

By doing so, we gain support for every weight level! :) * fix: Add all missing type declarations in TrueTypeFontFile

Hi,
We seen that the system fonts works right, but when we want add an external font ,this is not working.
This is my code:
`<?php
require_once DIR . '/vendor/autoload.php';
use SVG\SVG;
use SVG\Nodes\Structures\SVGFont;
use SVG\Nodes\Texts\SVGText;
$image = new SVG(100, 100);
$doc = $image->getDocument();
$fuente = new SVGFont('fontello', './fontello.ttf',true, "font/ttf" );
$texto = new SVGText("Hello World" , 10, 10);
$texto->setStyle('fill', '#FF00FF');
$texto = $texto->setFont($fuente);
$doc->addChild($texto);
header('Content-Type: image/svg+xml');
echo $image;`
The text was updated successfully, but these errors were encountered:
