      • processBitmap

        protected android.graphics.Bitmap processBitmap​(java.lang.Object data)
        从类复制的说明: EaseImageWorker
        Subclasses should override this to define any processing or work that must happen to produce the final bitmap. This will be executed in a background thread and be long running. For example, you could resize a large bitmap here, or pull down an image from the network.
        指定者:
        processBitmap 在类中 EaseImageWorker
        参数:
        data - The data to identify which image to process, as provided by EaseImageWorker.loadImage(Object, ImageView)
        返回:
        The processed bitmap

      • calculateInSampleSize

        public static int calculateInSampleSize​(android.graphics.BitmapFactory.Options options,
                                        int reqWidth,

        Calculate an inSampleSize for use in a BitmapFactory.Options object when decoding bitmaps using the decode* methods from BitmapFactory. This implementation calculates the closest inSampleSize that is a power of 2 and will result in the final decoded bitmap having a width and height equal to or larger than the requested width and height.
        参数:
        options - An options object with out* params already populated (run through a decode* method with inJustDecodeBounds==true
        reqWidth - The requested width of the resulting bitmap
        reqHeight - The requested height of the resulting bitmap
        返回:
        The value to be used for inSampleSize
