Constructors

BitmapFactory.Options() 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) BitmapFactory.Options(IntPtr, JniHandleOwnership)

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

Properties

Class Class

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

(Inherited from Object)
Handle Handle

The handle to the underlying Android instance.

(Inherited from Object)
IJavaObjectEx.IsProxy IJavaObjectEx.IsProxy Inherited from Object
IJavaObjectEx.KeyHandle IJavaObjectEx.KeyHandle Inherited from Object
IJavaObjectEx.NeedsActivation IJavaObjectEx.NeedsActivation Inherited from Object
IJavaPeerable.JniManagedPeerState IJavaPeerable.JniManagedPeerState Inherited from Object
InBitmap InBitmap

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

InDensity InDensity

The pixel density to use for the bitmap.

InDither InDither

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

InInputShareable InInputShareable

This field works in conjuction with inPurgeable.

InJustDecodeBounds 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 InMutable

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

InPreferQualityOverSpeed 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 InPreferredColorSpace
InPreferredConfig InPreferredConfig

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

InPremultiplied InPremultiplied
InPurgeable 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 InSampleSize

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

InScaled 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 InScreenDensity

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

InTargetDensity InTargetDensity

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

InTempStorage InTempStorage

Temp storage to use for decoding.

JniIdentityHashCode JniIdentityHashCode Inherited from Object
JniPeerMembers JniPeerMembers
MCancel MCancel

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

OutColorSpace OutColorSpace
OutConfig OutConfig
OutHeight OutHeight

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

OutMimeType OutMimeType

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

OutWidth OutWidth

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