- Method Detail
  - getSizeInBytes
```
 final static Integer getSizeInBytes(Bitmap bitmap)
```
  - decodeDimensions
```
 final static Pair<Integer, Integer> decodeDimensions(ByteArray bytes)
```
    Decodes only the bounds of an image and returns its width and height or null if the size can't be determined
    
    Parameters:
    
    bytes - the input byte array of the image
  - decodeDimensions
```
 final static Pair<Integer, Integer> decodeDimensions(Uri uri)
```
    Decodes the bounds of an image from its Uri and returns a pair of the dimensions
    
    Parameters:
    
    uri - the Uri of the image
  - decodeDimensions
```
 final static Pair<Integer, Integer> decodeDimensions(InputStream inputStream)
```
    Decodes the bounds of an image and returns its width and height or null if the size can't be determined
    
    Parameters:
    
    inputStream - the InputStream containing the image data
  - decodeDimensionsAndColorSpace
```
 final static ImageMetaData decodeDimensionsAndColorSpace(InputStream inputStream)
```
    Decodes the bounds of an image and returns its width and height or null if the size can't be determined. It also recovers the color space of the image, or null if it can't be determined.
    
    Parameters:
    
    inputStream - the InputStream containing the image data
  - getPixelSizeForBitmapConfig
```
 final static Integer getPixelSizeForBitmapConfig(Bitmap.Config bitmapConfig)
```
    Returns the amount of bytes used by a pixel in a specific [ ]
    
    Parameters:
    
    bitmapConfig - the android.graphics.Bitmap.Config for which the size in byte will be returned
  - getSizeInByteForBitmap
```
 final static Integer getSizeInByteForBitmap(Integer width, Integer height, Bitmap.Config bitmapConfig)
```
    Returns the size in byte of an image with specific size and [ ]
    
    Parameters:
    
    width - the width of the image
    
    height - the height of the image
    
    bitmapConfig - the android.graphics.Bitmap.Config for which the size in byte will be returned
  - setUseDecodeBufferHelper
```
 final static Unit setUseDecodeBufferHelper(Boolean useDecodeBufferHelper)
```
  - getALPHA_8_BYTES_PER_PIXEL
```
 final Integer getALPHA_8_BYTES_PER_PIXEL()
