Implementing the JS Canvas API in PHP (around GD). Not fully featured but in a way that allows to port code from JS to PHP.

Some time ago I read that really interesting blog post about [SVG placeholders](https://jmperezperez.com/svg-placeholders/).

In this repository I try to experiment with the different ideas from the article. I try to find out if it is possible to use them in a PHP application.

Experiments
-----------

[](#experiments)

### Colors

[](#colors)

Extracts some colors from an image. The implementation is forked from [ColorThiefPHP](https://github.com/ksubileau/color-thief-php). Unlike the original Black and White are allowed and the handling of the alpha transparency is different.

I treat alpha transparency as it would be with a white background.

### Gradients

[](#gradients)

A loose adoption of [Gradify](https://github.com/fraser-hemp/gradify). It extracts the four colors using the palette from the Colors experiment.

### Paths

[](#paths)

Traces an bitmap and creates SVG paths. Based on [ImageTracerJS](https://github.com/jankovicsandras/imagetracerjs).

### [Primitive](docs/primitive.md)

[](#primitive)

This concept tries to reproduce the original image using primitive shapes (triangle, rect, ellipse). Very few shapes and a strong blur the result is good impression of the image, already. The result is impressive, but it is expensive (cpu, memory) to create.

How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio. Uses a 2-year decay window.

**Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores.

**Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement.

**Maturity (30%)** — Project age, version count, PHP version support, and release stability.
