Color type and operations. Port of ae.utils.graphics.

Members

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.

structFields string[] structFields(): Evaluates to array of strings with name for each field.

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.

Color struct Color(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.
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.
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.
