8 is not a valid argument count for any overload.

I'm pretty sure TexImage2DAsync is currently not functional. At least, if it is, I haven't been able to figure out how to use it. The only workaround I could find was to create and call a js function that gets the canvas and runs texImage2D.

function addTextureToCanvas(imgId) {
    canvas = document.getElementsByTagName("canvas");
    var gl = canvas[0].getContext("webgl");

    var image = document.getElementById(imgId);
    gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, gl.UNSIGNED_BYTE, image);
    //gl.generateMipmap(gl.TEXTURE_2D);
}

I hope that helps.

it is no longer relevant, but thanks to your sources.. I was able to write an image generation based on byte [] await _context.DrawImageAsync(imagePngBytes, ImageFormat.PNG, OffsetX, OffSetY, (int)maxX, (int)maxY);

  // figure out which function type it's using
  var textureObj = this.textureUsage[this.activeTexture.__uuid];
