Greyify

An contao extension that provides a small class to greyscale images with PHP or inserttag

How to use:

inserttag

    Default:
    {{greyify::imagePath/UUID?width=x&height=x&mode=x}}  // returns an image tag with figure container
    
    SRC:
    {{greyify::src::imagePath/UUID?width=x&height=x&mode=x}}  // returns only the file path
    
    TAG:
    {{greyify::tag::imagePath/UUID?width=x&height=x&mode=x}}  // returns an image tag
    
    FIGURE:
    {{greyify::figure::imagePath/UUID?width=x&height=x&mode=x}}  // returns an image tag with figure container
    

php

    $image = Greyify::convert(imagePath/UUID?width=x&height=x&mode=x);  // returns only the path of the image

    $image = Greyify::getHTML(imagePath/UUID?width=x&height=x&mode=x);  // returns an image tag

    $image = Greyify::getHTML(imagePath/UUID?width=x&height=x&mode=x, true);  // returns an image tag with figure container

For the getHTML method there is as third parameter the "alt" value available The parameters width/height/mode are optional for both inserttag and php
