Bitmap.Config

public static final enum Bitmap.Config
extends Enum<Bitmap.Config>

java.lang.Object
↳	java.lang.Enum<android.graphics.Bitmap.Config>
	↳	android.graphics.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()` Throws CloneNotSupportedException.
`final int`	`compareTo(Bitmap.Config o)` Compares this enum with the specified object for order.
`final boolean`	`equals(Object other)` Returns true if the specified object is equal to this enum constant.
`final void`	`finalize()` enum classes cannot have finalize methods.
`final Class<Bitmap.Config>`	`getDeclaringClass()` Returns the Class object corresponding to this enum constant's enum type.
`final int`	`hashCode()` Returns a hash code for this enum constant.
`final String`	`name()` Returns the name of this enum constant, exactly as declared in its enum declaration.
`final int`	`ordinal()` Returns the ordinal of this enumeration constant (its position in its enum declaration, where the initial constant is assigned an ordinal of zero).
`String`	`toString()` Returns the name of this enum constant, as contained in the declaration.
`static <T extends Enum<T>> T`	`valueOf(Class<T> enumType, String name)` Returns the enum constant of the specified enum type with the specified name.

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Enum values

ALPHA_8

Added in API level 1

Bitmap.Config ALPHA_8

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.

ARGB_4444

Added in API level 1

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.

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.

ARGB_8888

Added in API level 1

Bitmap.Config ARGB_8888

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.

RGB_565

Added in API level 1

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. 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.
