ExpandNumericType alias ExpandNumericType(T, uint additionalBits) = ResizeNumericType!(T, valueBits!T + additionalBits): Expand to a built-in numeric type of the same kind (signed integer / unsigned integer / floating-point) with at least additionalBits more bits of precision.
L16 alias L16 = DefColor!(ushort, "l"): Undocumented in source.
L32f alias L32f = DefColor!(float, "l"): Undocumented in source.
L8 alias L8 = DefColor!(ubyte, "l"): Undocumented in source.
RGB alias RGB = DefColor!(ubyte, "r", "g", "b"): Undocumented in source.
RGBA alias RGBA = DefColor!(ubyte, "r", "g", "b", "a"): Undocumented in source.
RGBA16 alias RGBA16 = DefColor!(ushort, "r", "g", "b", "a"): Undocumented in source.
RGBAf alias RGBAf = DefColor!(float, "r", "g", "b", "a"): Undocumented in source.
RGBf alias RGBf = DefColor!(float, "r", "g", "b"): Undocumented in source.

blendColor RGB blendColor(RGB fg, RGB bg, ubyte alpha): Undocumented in source. Be warned that the author may not have intended to support it.
blendColor L16 blendColor(L16 fg, L16 bg, ushort alpha): Undocumented in source. Be warned that the author may not have intended to support it.
blendColor RGBA blendColor(RGBA fg, RGBA bg, ubyte alpha): Undocumented in source. Be warned that the author may not have intended to support it.
blendColorPremul RGBA blendColorPremul(RGBA fg, RGBA bg, ubyte alpha): Blend two colors, where fg is a premultiplied color by its own alpha. We consider fg to be already scaled by (alpha/255) Return: (255-alpha)
itpl T itpl(T low, T high, U r, U rLow, U rHigh): Undocumented in source. Be warned that the author may not have intended to support it.
sign byte sign(T x): Undocumented in source. Be warned that the author may not have intended to support it.
sort2 void sort2(T x, T y): Undocumented in source. Be warned that the author may not have intended to support it.
sqr auto sqr(T x): Undocumented in source. Be warned that the author may not have intended to support it.

FieldList mixintemplate FieldList(Fields...): Like std.typecons.Tuple, but a template mixin. Unlike std.typecons.Tuple, names may not be omitted - but repeating types may be.

structFields string[] structFields [@property getter]: Evaluates to array of strings with name for each field.

DefColor struct DefColor(FieldTuple...): Instantiates to a color type. FieldTuple is the color specifier, as parsed by the FieldList template from ae.utils.meta. 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

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 homogenous colors.
ExpandIntegerType template ExpandIntegerType(T, size_t bits): Wrapper around ExpandNumericType to only expand numeric types.
GenFieldList template GenFieldList(T, Fields...): Undocumented in source.
ResizeNumericType template ResizeNumericType(T, uint bits): Expand to a built-in numeric type of the same kind (signed integer / unsigned integer / floating-point) with at least the indicated number of bits of precision.
SignedBitsType template SignedBitsType(uint bits): Undocumented in source.
UnsignedBitsType template UnsignedBitsType(uint bits): Unsigned integer type big enough to fit N bits of precision.
valueBits template valueBits(T): Return the number of bits used to store the value part, i.e. T.sizeof*8 for integer parts and the mantissa size for floating-point types.
