decodeBitmapInBackground

public static void decodeBitmapInBackground(android.content.Context context,
                                            android.net.Uri uri,
                                            android.net.Uri outputUri,
                                            int requiredWidth,
                                            int requiredHeight,
                                            BitmapLoadCallback loadCallback)

transformBitmap

public static android.graphics.Bitmap transformBitmap(android.graphics.Bitmap bitmap,
                                                      android.graphics.Matrix transformMatrix)

calculateInSampleSize

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

getExifOrientation

public static int getExifOrientation(android.content.Context context,
                                     android.net.Uri imageUri)

exifToDegrees

public static int exifToDegrees(int exifOrientation)

exifToTranslation

public static int exifToTranslation(int exifOrientation)

calculateMaxBitmapSize

public static int calculateMaxBitmapSize(android.content.Context context)

This method calculates maximum size of both width and height of bitmap. It is twice the device screen diagonal for default implementation (extra quality to zoom image). Size cannot exceed max texture size.

Returns:

- max bitmap size in pixels.

close

public static void close(java.io.Closeable c)
