Bitmap getpixels

Returns a Bitmap representation of this TensorImage. Numeric casting and clamping will be applied if the stored data is not uint8. Note that, the reliable way to get pixels from an ALPHA_8 Bitmap is to use copyPixelsToBuffer. Bitmap methods such as, `setPixels()` and `getPixels` do not work. Important: it's only a reference. DO NOT MODIFY.
