solved Screenshot adding a callback to a callback

[joeBImagine]

Hello Babylon community!! I have a query concerning implementing a callback in a callback for taking a screenshot of cameras.  I have this function call 

createCameraView: function (camera)
{
    let src;
    BABYLON.Tools.CreateScreenshot(engine, camera,  { width: 293, height: 150 }, function (data) { src = data; });
    return src;
},

the callback function actually saves out the image for each camera (including the hidden on's) in the scene as a base64 to the images src tag, but that saving part takes time.  The part that I am confused about is actually setting up a callback for the callback, that lets me know when the image itself is done rendering.  I am sorry I do not have a playground as most of this code is internal.  And also please forgive me if this is not enough information to understand my issue.  Cheers!

If you pass in the function you wish to run as an argument to createCameraView, then call assign it as the callback, then ditch the let, your anonymous function & the return.

I think he means like a DOM image.onload callback, so when the screenshot has been made and is visible.

Aww yes! Something similar to a DOM image.onload callback.  But mainly for when it is fully made, so that I can update my react toolbar

So img.onload is not what you need?

Come to think of it, you are right.  I tried that before, but I wasn't implementing it correctly it would seem.  

 

let img = new Image();
    img.onload = function () {
   alert("image is loaded");
}
    img.src = src;
