MathOptions class

Options for equation element rendering.

Every GreenNode is rendered with an MathOptions. It controls their size, color, font, etc.

MathOptions is immutable. Each modification returns a new instance of MathOptions.

Methods

copyWith({MathStyle? style, Color? color, MathSize? sizeUnderTextStyle, FontOptions? textFontOptions, FontOptions? mathFontOptions}) → MathOptions
Utility method copyWith
havingBaseSize() → MathOptions
Returns MathOptions with size reset to MathSize.normalsize
havingCrampedStyle() → MathOptions
Returns MathOptions with their styles set to cramped (e.g. textCramped)
havingSize(MathSize size) → MathOptions
Returns MathOptions with their user-declared size set to given size
havingStyle(MathStyle style) → MathOptions
Returns MathOptions with given MathStyle
havingStyleUnderBaseSize(MathStyle? style) → MathOptions
Returns MathOptions with size reset to MathSize.normalsize and given style. If style is not given, then the current style will be increased to at least MathStyle.text
merge(OptionsDiff partialOptions) → MathOptions
Merge an OptionsDiff into current MathOptions
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.

withColor(Color color) → MathOptions
Returns MathOptions with given text color
withMathFont(FontOptions font) → MathOptions
Returns MathOptions with given math font
withTextFont(PartialFontOptions font) → MathOptions
Returns MathOptions with current text-mode font options merged with given font differences
