Convert images to grayscale on Wordpress with an automatic user upload conversion feature

Hey there!

I am currently in the process of developing a Wordpress website for a client. This site is using the Fancy Product Designer along with WooCommerce to sell custom engraved memory stones. These stones are black, with laser-etched engravings that create stunning grayscale text and imagery.

The client specifically wants all images uploaded to the Designer to be displayed in grayscale. This is to ensure customers do not have unrealistic expectations about receiving a color print, which the client cannot provide.

While the Fancy Product Designer has been helpful in solving many issues, we are facing a challenge due to the fact that individual elements within the designer cannot be accessed through CSS. This is because they are drawn on an HTML5 CANVAS element via the plugin's JQuery. Our initial attempt at applying a grayscale CSS overlay to the entire CANVAS element resulted in obstructing the red error messages built into the Designer.

My belief is that the key to addressing this issue lies in finding a suitable plugin or method capable of automatically converting user uploads to grayscale before integrating them as elements onto the CANVAS.

I would greatly appreciate any assistance you can offer. Thank you!

It turns out that the Fancy Product Designer relies on Fabric.js to manage its <canvas> elements. Surprisingly, only a few lines of code were needed:

var d = $("div.outermost"); //The outermost <div> containing the <canvas>.
var canvas = new fabric.Canvas('id');
var filter = new fabric.Image.filters.Grayscale();
d.on('elementAdded', function(evt, element){
    element.filters.push(filter);
    element.applyFilters(canvas.renderAll.bind(canvas));
});

With this simple setup, a grayscale filter was applied to every element added to the canvas without the need for complicated plugins or processes. For more information about the Fabric.js canvas method, click here.
