BGR alias BGR = Color!(ubyte, "b", "g", "r"): Definitions for common color types.
BGRA alias BGRA = Color!(ubyte, "b", "g", "r", "a"): Definitions for common color types.
BGRX alias BGRX = Color!(ubyte, "b", "g", "r", "x"): Definitions for common color types.
ExpandChannelType alias ExpandChannelType(COLOR, int BYTES) = ChangeChannelType!(COLOR, ExpandNumericType!(ChannelType!COLOR, BYTES * 8)): Resolves to a Color instance with its ChannelType expanded by BYTES bytes.
ExpandChannelTypeSigned alias ExpandChannelTypeSigned(COLOR, int BYTES) = ChangeChannelType!(COLOR, Signed!(ExpandNumericType!(ChannelType!COLOR, BYTES * 8))): Resolves to a Color instance with its ChannelType expanded by BYTES bytes and made signed.
L16 alias L16 = Color!(ushort, "l"): Definitions for common color types.
L8 alias L8 = Color!(ubyte, "l"): Definitions for common color types.
LA alias LA = Color!(ubyte, "l", "a"): Definitions for common color types.
LA16 alias LA16 = Color!(ushort, "l", "a"): Definitions for common color types.
OneBitStorageBE alias OneBitStorageBE = BitStorageUnit!(bool, 1, ubyte, true): 8 monochrome bits packed into a byte, in the usual big-endian order.
OneBitStorageLE alias OneBitStorageLE = BitStorageUnit!(bool, 1, ubyte, false): As above, but in little-endian order.
PlainStorageUnit alias PlainStorageUnit(Color) = Color[1]: Color storage unit for as-is storage.
RGB alias RGB = Color!(ubyte, "r", "g", "b"): Definitions for common color types.
RGB16 alias RGB16 = Color!(ushort, "r", "g", "b"): Definitions for common color types.
RGBA alias RGBA = Color!(ubyte, "r", "g", "b", "a"): Definitions for common color types.
RGBA16 alias RGBA16 = Color!(ushort, "r", "g", "b", "a"): Definitions for common color types.
RGBX alias RGBX = Color!(ubyte, "r", "g", "b", "x"): Definitions for common color types.
RGBX16 alias RGBX16 = Color!(ushort, "r", "g", "b", "x"): Definitions for common color types.
RGBd alias RGBd = Color!(double, "r", "g", "b"): Definitions for common color types.
RGBf alias RGBf = Color!(float, "r", "g", "b"): Definitions for common color types.
S16 alias S16 = Color!(short, "l"): Definitions for common color types.
S8 alias S8 = Color!(byte, "l"): Definitions for common color types.
StorageColor alias StorageColor(StorageType) = typeof(StorageType.init[0]): Get the color value of a storage unit type.
blend deprecated alias blend = _blend: Undocumented in source.

Functions

_blend T _blend(T f, T b, T a): Undocumented in source. Be warned that the author may not have intended to support it.
solidStorageUnit StorageType solidStorageUnit(StorageColor!StorageType color): Construct a StorageType with all colors set to the indicated value.

Structs

BitStorageUnit struct BitStorageUnit(ValueType, size_t valueBits, StorageType, bool bigEndian): Color storage unit description for packed bit colors (1-bit, 2-bit, 4-bit etc.)
Color struct Color(FieldTuple...): Represents a tuple of samples, usually used to represent a single color in some color space. This helper type allows manipulating such tuples more easily, and has special behavior for common color representations (e.g. special treatment of the "a" field as an alpha channel, and construction from hex strings for R/G/B colors). FieldTuple is a field spec, as parsed by ae.utils.meta.FieldList. By convention, each field's name indicates its purpose: - x: padding - a: alpha - l: lightness (or grey, for monochrome images) - others (r, g, b, etc.): color information
Gradient struct Gradient(Value, Color): Calculate an interpolated color on a gradient with multiple points

Templates

ChangeChannelType template ChangeChannelType(COLOR, T): Resolves to a Color instance with a different ChannelType.
ChannelType template ChannelType(T): Obtains the type of each channel for homogeneous colors.
ExpandIntegerType template ExpandIntegerType(T, size_t bits): Wrapper around ExpandNumericType to only expand integer types.
TransformChannelType template TransformChannelType(COLOR, alias Transformer): Resolves to a Color instance with a different ChannelType.
channelMap template channelMap(T, alias expr = a => a)
template channelMap(alias expr): Applies a transformation per-channel. expr may be in the form of a => ..., or (a, ref b) { b = ...; } (only if T is explicitly specified).

Variables

isStorageColorLValue enum bool isStorageColorLValue(StorageType);: True when we can take the address of an individual color within a storage unit.
storageColorBits enum size_t storageColorBits(StorageType);: The number of bits that one individual color takes up.
