Constructors

BitmapFactory.Options()

Create a default Options object, which if left unchanged will give the same result from the decoder as if null were passed.

BitmapFactory.Options(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

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)
InBitmap

If set, decode methods that take the Options object will attempt to reuse this bitmap when loading content.

InDensity

The pixel density to use for the bitmap.

InDither

If dither is true, the decoder will attempt to dither the decoded image.

InInputShareable

This field works in conjuction with inPurgeable.

InJustDecodeBounds

If set to true, the decoder will return null (no bitmap), but the out... fields will still be set, allowing the caller to query the bitmap without having to allocate the memory for its pixels.

InMutable

If set, decode methods will always return a mutable Bitmap instead of an immutable one.

InPreferQualityOverSpeed

If inPreferQualityOverSpeed is set to true, the decoder will try to decode the reconstructed image to a higher quality even at the expense of the decoding speed.

InPreferredColorSpace
InPreferredConfig

If this is non-null, the decoder will try to decode into this internal configuration.

InPremultiplied
InPurgeable

If this is set to true, then the resulting bitmap will allocate its pixels such that they can be purged if the system needs to reclaim memory.

InSampleSize

If set to a value > 1, requests the decoder to subsample the original image, returning a smaller image to save memory.

InScaled

When this flag is set, if InDensity and InTargetDensity are not 0, the bitmap will be scaled to match InTargetDensity when loaded, rather than relying on the graphics system scaling it each time it is drawn to a Canvas.

InScreenDensity

The pixel density of the actual screen that is being used.

InTargetDensity

The pixel density of the destination this bitmap will be drawn to.

InTempStorage

Temp storage to use for decoding.

JniIdentityHashCode (Inherited from Object)
JniPeerMembers
MCancel

Flag to indicate that cancel has been called on this object.

OutColorSpace
OutConfig
OutHeight

The resulting height of the bitmap, set independent of the state of inJustDecodeBounds.

OutMimeType

If known, this string is set to the mimetype of the decoded image.

OutWidth

The resulting width of the bitmap, set independent of the state of inJustDecodeBounds.

Methods

Clone()

Creates and returns a copy of this Object.

(Inherited from Object)
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)
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)
RequestCancelDecode()
Obsolete.

This can be called from another thread while this options object is inside a decode... call.

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.
