Extension method for checking if the bitmap is empty

[kevalpatel2106]

I think it would be great if bitmap has an extension for checking if the bitmap is empty or not based on the byte count.

if (bitmap.isEmpty()){
   // Did not read bitmap correctly.
}

Why based on byte count and not size?

I didn't use size because createBitmap doesn't allow to set the bitmap dimensions to zero. So there is no point of checking the size of the bitmap to see if the bitmap is of 0 * 0 size.
