Enum DecodeFormat

java.lang.Object

java.lang.Enum<DecodeFormat>

com.bumptech.glide.load.DecodeFormat

All Implemented Interfaces:

Serializable, Comparable<DecodeFormat>

public enum DecodeFormat
extends Enum<DecodeFormat>

Options for setting the value of Bitmap.getConfig() for Bitmaps returned by a BitmapDecoder.

Note - In some cases it may not be possible to obey the requested setting, not all BitmapDecoders support setting formats and certain images may not be able to be loaded as certain configurations. Therefore this class represents a preference rather than a requirement.

Enum Constant Summary

Enum Constants

Enum Constant and Description
ALWAYS_ARGB_8888 Deprecated. Use the equivalent but less misleadingly named PREFER_ARGB_8888. Scheduled to be removed in Glide 4.0
PREFER_ARGB_8888 Bitmaps decoded from most image formats (other than GIFs with hidden configs), will be decoded with the ARGB_8888 config.
PREFER_RGB_565 Bitmaps decoded from image formats that support and/or use alpha (some types of PNGs, GIFs etc) should return Bitmap.Config.ARGB_8888 for Bitmap.getConfig().

Enum Constant Detail

ALWAYS_ARGB_8888

@Deprecated
public static final DecodeFormat ALWAYS_ARGB_8888

Deprecated. Use the equivalent but less misleadingly named PREFER_ARGB_8888. Scheduled to be removed in Glide 4.0

All bitmaps returned by the BitmapDecoder should return Bitmap.Config.ARGB_8888 for Bitmap.getConfig().

PREFER_ARGB_8888

public static final DecodeFormat PREFER_ARGB_8888

Bitmaps decoded from most image formats (other than GIFs with hidden configs), will be decoded with the ARGB_8888 config.

BitmapFactory does not allow us to guarantee that all returned Bitmaps will be of a requested config without resorting to expensive copying. As a result, this is a preference only. Most GIFs, for example, will still produce Bitmaps with null Bitmap.Configs.

PREFER_RGB_565

public static final DecodeFormat PREFER_RGB_565

Bitmaps decoded from image formats that support and/or use alpha (some types of PNGs, GIFs etc) should return Bitmap.Config.ARGB_8888 for Bitmap.getConfig(). Bitmaps decoded from formats that don't support or use alpha should return Bitmap.Config.RGB_565 for Bitmap.getConfig().

Field Detail

DEFAULT

public static final DecodeFormat DEFAULT

The default value for DecodeFormat.

Method Detail

values

public static DecodeFormat[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DecodeFormat c : DecodeFormat.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DecodeFormat valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
