edwrodrig\image

Library to create optimized images and thumbnails for web, and compare images.

My use cases

Make a area contained thumbnail.
Create a area cover thumbnail.
Load SVG files transparently.
Optimize for web to meet the PageSpeed Insights suggestions about optimizing images.
Create small preview thumbnails of about <1Kb suitable for database columns.
Compare images to detect duplicates.
Enhance document images (diagrams, text, lineart)

My infrastructure is targeted to Ubuntu 16.04 machines with last php7.4 installed from ppa:ondrej/php

Documentation

The source code is documented using phpDocumentor style, so it should pop up nicely if you're using IDEs like PhpStorm or similar.

Testing

The test are built using PhpUnit. It generates images and compare the signature with expected ones. Maybe some test fails due metadata of some generated images, but at the moment I haven't any reported issue.

About language

I'm not a native english writer, so there may be a lot of grammar and orthographical errors on text, I'm just trying my best. But feel free to correct my language, any contribution is welcome and for me they are a learning instance.
