如何从KingfisherManager中的restoreImage返回的图像实例中获取图像格式？

Question

是否有任何API返回Kingfisher缓存的图像的图像格式？

textWatcher = new StringUtils.NumberTextWatcherForThousand(mAmountEditText);
public void enableTextChangedListener(boolean enableFormatting){
    if (enableFormatting) {
        if (!"1".equals(mAmountEditText.getTag())) {
            mAmountEditText.addTextChangedListener(textWatcher);
            mAmountEditText.setTag("1");

}
    }
    else {
        mAmountEditText.removeTextChangedListener(textWatcher);
    }
}
