"LaTeXML::Common::Color" - abstract class representating colors using various color models; extends LaTeXML::Common::Object. Exported functions "$color = Color($model,@components);" Creates a Color object using the given color model, and with the given components. The core color models are "rgb", "hsv", "cmy", "cmyk" and "gray". The components of colors using core color models are between 0 and 1 (inclusive) "Black", "White" Constant color objects representing black and white, respectively. Methods "$model = $color->model;" Return the name of the color model. "@components = $color->components;" Return the components of the color. "$other = $color->convert($tomodel);" Converts the color to another color model. "$string = $color->toString;" Returns a printed representation of the color. "$hex = $color->toHex;" Returns a string representing the color as RGB in hexadecimal (6 digits). "$other = $color->toCore();" Converts the color to one of the core colors. "$complement = $color->complement();" Returns the complement color (works for colors in "rgb", "cmy" and "gray" color models). "$new = $color->mix($other,$fraction);" Returns a new color which results from mixing a $fraction of $color with "(1-$fraction)" of color $other. "$new = $color->add($other);" Returns a new color made by adding the components of the two colors. "$new = $color->scale($m);" Returns a new color made by mulitiplying the components by $n. "$new = $color->multiply(@m);" Returns a new color made by mulitiplying the components by the corresponding component from @n.
