[GUI] How to apply tint to an image?


Recommended Posts

Hi everyone, I have gui assets from my previous Unity project - mostly greyscale textures. That's because we've been using tint color on ui elements to make it easier to adjust color palette project-wide, and also to create color transitions on ui elements.

Is there any way to replicate that behaviour in Babylon? The only thing I've figured out so far is to use the css hue filter, but I can't get even that to work.

Here's a playground (the texture is not really suitable, but I just want to achieve a proof of concept)

Hello and welcome!!

The GUI is rendered using HTML canvas 2d operations and thus we can use composite operations (https://stackoverflow.com/questions/2688961/how-do-i-tint-an-image-with-html5-canvas)


You could probably replace control._draw but if you are interested I could add a new observable (like control.onBeforeDrawObservable) so you could change the current canvas context
