Informations about the package geopattern
GeoPattern
This is a PHP port of jasonlong/geo_pattern.
Generate beautiful tiling SVG patterns from a string. The string is converted into a SHA and a color and pattern are determined based on the values in the hash. The color is determined by shifting the hue and saturation from a default (or passed in) base color. One of 16 patterns is used (or you can specify one) and the sizing of the pattern elements is also determined by the hash values.
You can use the generated pattern as the background-image
for a container. Using the base64
representation of the pattern still results in SVG rendering, so it looks great on retina displays.
See the GitHub Guides site as an example of what this library can do. (GitHub Guides uses the original ruby version).
Installation
Run this command in your root project:
Installation (without composer)
Download or clone the src
directory from GitHub.
Rename the src
folder to GeoPattern
and put it somewhere your app can access it from.
Add this line to your code:
require_once('path/to/folder/geopattern_loader.php');
You can then follow the usage instructions below.
Usage
Make a new pattern:
$geopattern = new \RedeyeVentures\GeoPattern\GeoPattern();
$geopattern->setString('Mastering Markdown');
To specify a base background color (with a hue and saturation that adjusts depending on the string):
$geopattern->setBaseColor('#ffcc00');
To use a specific background color (w/o any hue or saturation adjustments):
$geopattern->setColor('#ffcc00');
To use a specific pattern generator:
$geopattern->setGenerator('sine_waves');
Get the SVG string:
$svg = $geopattern->toSVG();
Get the Base64 encoded string:
$base64 = $geopattern->toBase64();
Get a data URI:
$dataURI = $geopattern->toDataURI(); #data:image/svg+xml;base64,...
Get a data URL:
$dataURL = $geopattern->toDataURL(); #url("data:image/svg+xml;base64,...")
You can use the data URL string to set the background:
<div style="background-image: {$dataURL)"></div>
The setString
, setBaseColor
, setGenerator
methods are chainable.
You can also pass an array to the GeoPattern constructor containing the string
, baseColor
, color
, and/or generator
values.
If the GeoPattern object is cast as a string, it will provide the SVG string.
