Bitmap.Config

Possible bitmap configurations. A bitmap configuration describes how pixels are stored. This affects the quality (color depth) as well as the ability to display transparent/translucent colors.

Summary

Enum Values
Bitmap.Config	ALPHA_8	Each pixel is stored as a single translucency (alpha) channel.
Bitmap.Config	ARGB_4444	This field was deprecated in API level 13. Because of the poor quality of this configuration, it is advised to use `ARGB_8888` instead.
Bitmap.Config	ARGB_8888	Each pixel is stored on 4 bytes.
Bitmap.Config	RGB_565	Each pixel is stored on 2 bytes and only the RGB channels are encoded: red is stored with 5 bits of precision (32 possible values), green is stored with 6 bits of precision (64 possible values) and blue is stored with 5 bits of precision.

Inherited Methods

From class java.lang.Enum

final Object	clone() `Enum` objects are singletons, they may not be cloned.
final int	compareTo(Bitmap.Config o) Compares this object to the specified enum object to determine their relative order.
final boolean	equals(Object other) Compares this object with the specified object and indicates if they are equal.
final void	finalize() Enum types may not have finalizers.
final Class<Bitmap.Config>	getDeclaringClass() Returns the enum constant's declaring class.
final int	hashCode() Returns an integer hash code for this object.
final String	name() Returns the name of this enum constant.
final int	ordinal() Returns the position of the enum constant in the declaration.
String	toString() Returns a string containing a concise, human-readable description of this object.
static <T extends Enum<T>> T	valueOf(Class<T> enumType, String name) Returns the constant with the specified name of the specified enum type.

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	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.
final void	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.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Enum Values

public static final Bitmap.Config ALPHA_8

Added in API level 1

Each pixel is stored as a single translucency (alpha) channel. This is very useful to efficiently store masks for instance. No color information is stored. With this configuration, each pixel requires 1 byte of memory.

public static final Bitmap.Config ARGB_4444

Added in API level 1

This field was deprecated in API level 13.
Because of the poor quality of this configuration, it is advised to use ARGB_8888 instead.

Each pixel is stored on 2 bytes. The three RGB color channels and the alpha channel (translucency) are stored with a 4 bits precision (16 possible values.) This configuration is mostly useful if the application needs to store translucency information but also needs to save memory. It is recommended to use ARGB_8888 instead of this configuration. Note: as of KITKAT, any bitmap created with this configuration will be created using ARGB_8888 instead.

public static final Bitmap.Config ARGB_8888

Added in API level 1

Each pixel is stored on 4 bytes. Each channel (RGB and alpha for translucency) is stored with 8 bits of precision (256 possible values.) This configuration is very flexible and offers the best quality. It should be used whenever possible.

public static final Bitmap.Config RGB_565

Added in API level 1

Each pixel is stored on 2 bytes and only the RGB channels are encoded: red is stored with 5 bits of precision (32 possible values), green is stored with 6 bits of precision (64 possible values) and blue is stored with 5 bits of precision. This configuration can produce slight visual artifacts depending on the configuration of the source. For instance, without dithering, the result might show a greenish tint. To get better results dithering should be applied. This configuration may be useful when using opaque bitmaps that do not require high color fidelity.
