AtelierSVG

Read, build, and serialise SVG with nothing but PHP.

Treat SVG as a document, not a string. Generate graphics, edit existing assets, accept uploads safely, and prepare files for production.

A document, not a string
Every element is a class with its own attributes. Load a file, walk the tree, change it, write it back.
CSS selectors
querySelector() and querySelectorAll() find the nodes. What comes back is a typed, chainable collection rather than an array.
Paths become segments
The d attribute parses into typed segments. Measure a length, sample a point along the curve, take a bounding box, simplify, bake a transform into coordinates.
Accept uploads safely
The strict profile removes script elements, event handlers, javascript: URLs and <foreignObject>; two softer ones keep more. Validation is separate, for when you need the report instead of the removal.
Ship smaller files
Forty-seven passes, and four presets that choose for you. optimizeWith() takes a pipeline you assembled instead, and a new pass is an interface rather than a fork.
Morph between shapes
Interpolate two paths whatever their segment counts, then export the frames as SMIL, CSS keyframes, JavaScript, or a sprite sheet.

Create an SVG

use Atelier\Svg\Svg;

Svg::create(300, 200)
    ->rect(0, 0, 300, 200, ['fill' => '#0f172a'])
    ->circle(150, 100, 60, ['fill' => '#6366f1'])
    ->save('output.svg');

Make an uploaded SVG safe

use Atelier\Svg\Svg;

use Atelier\Svg\Sanitizer\SanitizeProfile;

Svg::load('untrusted.svg')
    ->sanitize(SanitizeProfile::STRICT)
    ->save('safe.svg');

Prepare an icon for the web

Svg::load('icon.svg')
    ->optimizeWeb()
    ->save('icon.min.svg');

optimizeWeb() removes delivery-only weight such as dimensions and unused IDs. Use optimizeSafe() for design assets where metadata and IDs must remain intact.

Documentation

Start

Installation: install the package and check the PHP requirements.
Quick start: create, load, edit, and save a first document.

Documents and graphics

Document API: create, parse, validate, sanitize, and export complete SVG documents.
Elements: work with shapes, text, gradients, filters, clipping, animation, and accessibility.
Paths: build path data, inspect geometry, transform segments, and simplify curves.
Styling: compose transforms, layout values, and presentation attributes.

Production

Sanitization: remove unsafe content from uploaded SVG.
Optimization: clean and reduce documents with presets or custom passes.
Morphing: interpolate compatible outlines and export the animation.
