Properties

Class

Returns the unique instance of Class that represents this object's class.

(Inherited from Object)
Handle

The handle to the underlying Android instance.

(Inherited from Object)
Height

Returns the original image's height

IsRecycled

Returns true if this region decoder has been recycled.

JniIdentityHashCode (Inherited from Object)
JniPeerMembers
PeerReference (Inherited from Object)
ThresholdClass

(Inherited from Object)
Width

Returns the original image's width

Methods

Clone()

Creates and returns a copy of this Object.

(Inherited from Object)
DecodeRegion(Rect, BitmapFactory+Options)

Decodes a rectangle region in the image specified by rect.

Dispose() (Inherited from Object)
Dispose(Boolean) (Inherited from Object)
Equals(Object)

Compares this instance with the specified object and indicates if they are equal.

(Inherited from Object)
GetHashCode()

Returns an integer hash code for this object.

(Inherited from Object)
JavaFinalize()

Invoked when the garbage collector has detected that this instance is no longer reachable.

(Inherited from Object)
NewInstance(Byte[], Int32, Int32, Boolean)

Create a BitmapRegionDecoder from the specified byte array.

NewInstance(FileDescriptor, Boolean)

Create a BitmapRegionDecoder from the file descriptor.

NewInstance(Stream, Boolean)

Create a BitmapRegionDecoder from an input stream.

NewInstance(String, Boolean)

Create a BitmapRegionDecoder from a file path.

Notify()

Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.

(Inherited from Object)
NotifyAll()

Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.

(Inherited from Object)
Recycle()

Frees up the memory associated with this region decoder, and mark the region decoder as "dead", meaning it will throw an exception if decodeRegion(), getWidth() or getHeight() is called.

SetHandle(IntPtr, JniHandleOwnership)

Sets the Handle property.

(Inherited from Object)
ToArray<T>() (Inherited from Object)
ToString()

Returns a string containing a concise, human-readable description of this object.

(Inherited from Object)
UnregisterFromRuntime() (Inherited from Object)
Wait()

Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.

(Inherited from Object)
Wait(Int64)

Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.

(Inherited from Object)
Wait(Int64, Int32)

Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
