WebGLRenderingContext.texImage2D doesn't allow passing ImageBitmap as a parameter

[Fox32]

I would like to pass a ImageBitmapfor the border_OR_canvas_OR_image_OR_pixels_OR_video parameter of WebGLRenderingContext.texImage2D. However, internaly texImage2D checks for the type of the parameter and only allows ImageData, ImageElement, CanvasElementor VideoElement and throws an argument error otherwise.

For now I was able hack something together with dart:js that works, however it would be easier if I could just pass the parameter. I'm not sure if it's the easiest way to achieve it, but if anyone has a better idea, I would be happy about a response:

      final glEx = new JsObject.fromBrowserObject(context);

      glEx['o'].callMethod('texImage2D', [_textureTarget, 0, pixelFormat, pixelFormat, pixelDataType, new JsObject.fromBrowserObject(element)['o']]);

According to the IDL the valid forms are

    [RaisesException] void texImage2D(
        GLenum target, GLint level, GLenum internalformat,
        GLsizei width, GLsizei height, GLint border,
        GLenum format, GLenum type, ArrayBufferView? pixels);
    [RaisesException] void texImage2D(
        GLenum target, GLint level, GLenum internalformat,
        GLenum format, GLenum type, ImageData? pixels);
    [RaisesException] void texImage2D(
        GLenum target, GLint level, GLenum internalformat,
        GLenum format, GLenum type, HTMLImageElement image);
    [RaisesException] void texImage2D(
        GLenum target, GLint level, GLenum internalformat,
        GLenum format, GLenum type, HTMLCanvasElement canvas);
    [RaisesException] void texImage2D(
        GLenum target, GLint level, GLenum internalformat,
        GLenum format, GLenum type, HTMLVideoElement video);

So it doesn't seem like ImageBitmap ought to be allowed, unless there's some automatic conversion going on. Since the other parameters vary, without an IDL definition we don't know what they're supposed to be. I'd think about the best we could do is provide a completely dynamic pass-through version and hope the arguments get accepted in JS, but that's roughly what you're doing.

ImageBitmap was added to TexImageSource in the latest WebGL 1.0 IDL.

This seems to be fixed about a year long ago.

Imagebitmap is now supported.
