Color class - less library

Constructors

Color(String rgb, [dynamic alpha = 1, String originalForm]): The end goal here, is to parse the arguments into an integer triplet, such as 128, 255, 0 [...]
Color.fromKeyword(String keyword): factory
Color.fromList(dynamic rgb, [dynamic alpha = 1, String originalForm]): rgb is a List 128, 255, 0 or 62.2, 125.5, 67 The decimal arguments came from color operations [...]

Methods

accept(VisitorBase visitor) → void: inherited
addVisibilityBlock() → void: inherited
blocksVisibility() → bool: Returns true if this node represents root of was imported by reference
inherited
compare(Node xx) → int: Returns -1, 0 for different, equal
override
copyVisibilityInfo(VisibilityInfo info) → void: This node get the visibility from info
inherited
ensureInvisibility() → void: Turns off node visibility - if called node will NOT be shown in output regardless of whether it comes from import by reference or not
inherited
ensureVisibility() → void: Turns on node visibility, that is, if called node will be shown in output regardless of whether it comes from import by reference or not
inherited
eval(Contexts env) → Node: override
fileInfo() → FileInfo: returns fileInfo from this node or their parent
inherited
fround(Contexts context, num value, [int precision]) → num: Adjust the precision of value according to context.numPrecision. 8 By default. [...]
inherited
genCSS(Contexts context, Output output) → void: override
genTree(Contexts env, Output output, [String prefix = '']) → void: Writes in output the tree, for debug
inherited
genTreeField(Contexts env, Output output, String fieldName, dynamic fieldValue) → void: Build the subtree for a fieldName, fieldValue
inherited
genTreeTitle(Contexts env, Output output, String prefix, String type, String value) → void: Build the node tree title
inherited
getIndex() → int: returns index from this node or their parent
inherited
isCharset() → bool: Directive overrides it
inherited
isRulesetLike() → bool: inherited
isVisible() → bool: return values: false - the node must not be visible true - the node must be visible null - the node has the same visibility as its parent
inherited
luma() → double: Calculates the luma (perceptual brightness) of a color object Value between 0 for darkest and 1 for lightest.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed. [...]
inherited
operate(Contexts context, String op, Color other) → Color: Operations have to be done per-channel, if not, channels will spill onto each other. Once we have our result, in the form of an integer triplet, we create a new Color node to hold the result.
