Hi,

according to the webgl reference:
http://www.khronos.org/files/webgl/webg ... rd-1_0.pdf
It says under texImage2D object:
"pixels of type ImageData".

So I tried load a Image like so:
Code :
       var canvas = document.createElement("canvas");
        canvas.width = 256;
	    canvas.height = 256;
 
	var ctx = canvas.getContext("2d");
	var myImageData = ctx.createImageData(256,256);
	myImageData.width = 256;
	myImageData.height = 256;
 
	function setPixel(imageData, x, y, r, g, b, a) {
	    index = (x + y * imageData.width) * 4;
	    imageData.data[index+0] = r;
	    imageData.data[index+1] = g;
	    imageData.data[index+2] = b;
	    imageData.data[index+3] = a;
	}
 
	for (var x = 0; x < 256; x++) {
		for (var y = 0; y < 256; y++) {
			setPixel(myImageData, x, y, 255,0,0,255);
		}
	}
 
  _gl.pixelStorei(_gl.UNPACK_FLIP_Y_WEBGL, true);
 
  _gl.bindTexture(_gl.TEXTURE_2D, ert);
	_gl.texImage2D(_gl.TEXTURE_2D, 0, _gl.RGBA, 256, 256, 0, _gl.RGBA, _gl.UNSIGNED_BYTE, myImageData.data);

I left out not necessary code for readability reasons. If I use a "normal" image object it works as expected.

What am I doing wrong here?

Best regards, S.
