load method

@override void load(int x, int y, Float32List out)

Writes the texel at (x, y) of the base level into rgba, as four floats from nought to one, or four zeros outside the texture.

Implementation

@override
void load(int x, int y, Float32List out) {
  if (x < 0 || y < 0 || x >= width || y >= height) {
    out.fillRange(0, 4, 0);
    return;
  }
  final at = (y * width + x) * 4;
  for (var c = 0; c < 4; c++) {
    out[c] = unormValue(rgba[at + c]);
  }
}
