ColorType

enum ColorType : Enum<ColorType>

Describes how pixel bits encode color. A pixel may be an alpha mask, a grayscale, RGB, or ARGB.

Properties

val bytesPerPixel: Int

Returns the number of bytes required to store a pixel, including unused padding. Returns zero for .UNKNOWN.

val entries: EnumEntries<ColorType>

Returns a representation of an immutable list of all enum entries, in the order they're declared.

val isAlwaysOpaque: Boolean

Returns true if ColorType always decodes alpha to 1.0, making the pixel fully opaque. If true, ColorType does not reserve bits to encode alpha.

val name: String

val ordinal: Int

val shiftPerPixel: Int

validateAlphaType

fun validateAlphaType(alphaType: ColorAlphaType): ColorAlphaType?

Returns a valid ColorAlphaType for colorType. If there is more than one valid canonical ColorAlphaType, set to alphaType, if valid.

fun valueOf(value: String): ColorType

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.)

fun values(): Array<ColorType>

Returns an array containing the constants of this enum type, in the order they're declared.
