Image is not included in final file

[Luke-SF]

I'm having issues creating a png including an image: and when I run this minimal example, it is not saving the image or the text?

<?php
require 'vendor/autoload.php';

use SVG\SVG;
use SVG\Nodes\Structures\SVGDocumentFragment;
use SVG\Nodes\Embedded\SVGImage;
use SVG\Nodes\Texts\SVGText;
use SVG\Rasterization\Renderers\ImageRenderer;
use SVG\Rasterization\SVGRasterizer;

// Create a new SVG document
$svg = new SVG(100,100);
$doc = $svg->getDocument();

// Define the image parameters
$png = '/yourpathtosome.png'; // Ensure this path is correct
$x = 10;
$y = 10;
$width = 50;
$height = 50;

// Create and add the image to the document
$image = new SVGImage($png, $x, $y, $width, $height);
$doc->addChild($image);

// Optionally, add some text to verify the document structure
$text = new SVGText('Hello, SVG!', 20, 20);
$doc->addChild($text);

// Output the SVG content
#header('Content-Type: image/svg+xml');
echo $svg;
$rasterImage = $svg->toRasterImage(100, 100);
        imagepng($rasterImage, '/tmp/out.png');

This is on PHP8.4,
"meyfa/php-svg": "^0.9.1",
and gd is installed. It's outputting an empty png. The svg output looks okay.

Looks as though this example works in php-svg 0.14.x due to #189

However this newer library version doesn't have SVGFont class..? How would one set the fonts as we did before with SVGFont(name,file) objects?

You're probably right that you're encountering the same issue as #189 when trying to render an SVG with an image.

Regarding font addition, it's still possible, but the approach has changed somewhat since v0.9. I took a quick look at the old source but couldn't immediately determine the expected file type in the previous implementation (i.e., SVGFont(name, file)). The new approach now uses TTF files, which need to be added using SVG::addFont() before rendering.

The updated method is documented in the README. You can now load fonts as shown in the example below.

Hope this helps (feel free to close the issue), let me know if you have any more questions.

<?php
require __DIR__ . '/vendor/autoload.php';

use SVG\SVG;

// load a set of fonts from the "fonts" directory relative to the script directory
SVG::addFont(__DIR__ . '/fonts/Ubuntu-Regular.ttf');
SVG::addFont(__DIR__ . '/fonts/Ubuntu-Bold.ttf');
SVG::addFont(__DIR__ . '/fonts/Ubuntu-Italic.ttf');
SVG::addFont(__DIR__ . '/fonts/Ubuntu-BoldItalic.ttf');

$image = SVG::fromString('
<svg width="220" height="220">
  <rect x="0" y="0" width="100%" height="100%" fill="lightgray"/>
  <g font-size="15">
    <text y="20">hello world</text>
    <text y="100" font-weight="bold">in bold!</text>
    <text y="120" font-style="italic">and italic!</text>
    <text y="140" font-weight="bold" font-style="italic">bold and italic</text>
  </g>
</svg>
');

header('Content-Type: image/png');
imagepng($image->toRasterImage(220, 220));

specifying width and height along with viewbox helped me
by default SVG->render() does not specify width and height!
