    • writeCssText

      public void writeCssText(SimpleWriter wri) throws IOException
      Description copied from interface: CSSValue
      Serialize this value to a SimpleWriter.
      Specified by:
      writeCssText in interface CSSValue
      Overrides:
      writeCssText in class ColorValue
      Parameters:
      wri - the SimpleWriter.
      Throws:

    • getComponent

      public PrimitiveValue getComponent(int index)
      Description copied from class: ColorValue
      Get the color component at index.

      This method allows to access the color components like if they were indexed. It is convenient to perform common tasks at the components (like when computing values).

      Specified by:
      getComponent in class ColorValue
      Parameters:
      index - the index. Index 0 is always the alpha channel.
      Returns:
      the color component, or null if the index is incorrect.

    • setComponent

      public void setComponent(int index, StyleValue component)
      Description copied from class: TypedValue
      If this value has components, set the component at index.

      This method allows to access the components regardless of them being formally indexed or not. It is convenient to perform common tasks at the components (like when computing values).

      Overrides:
      setComponent in class ColorValue
      Parameters:
      index - the index. For colors, index 0 is always the alpha channel. Setting a component at an index that does not exist has no effect.
      component - the new component. Cannot be a KEYWORD nor a SHORTHAND. For colors, must be a primitive value (that is, either TYPED or a PROXY).

    • toRGBColor

      public RGBAColor toRGBColor() throws DOMException
      Description copied from interface: CSSTypedValue
      If this value represents a color, get it or transform to a RGB color.

      If the color does not map into the sRGB gamut, it is clamped.

      Specified by:
      toRGBColor in interface CSSTypedValue
      Returns:
      the RGBA color.
      Throws:
      DOMException - INVALID_ACCESS_ERR: if this value can't return a RGB color value (either is not a COLOR or not a typed value).
      NOT_SUPPORTED_ERR: if the conversion needs device color space information to be performed accurately.

    • toRGBColor

      public RGBAColor toRGBColor(boolean clamp) throws DOMException
      Description copied from interface: CSSColorValue
      Get the RGB(A) color representation of this value.

      The returned value is implicitly in the sRGB color space, unless stated otherwise.

      Specified by:
      toRGBColor in interface CSSColorValue
      Parameters:
      clamp - true if the converted value has to be clamped when it does not fall into the sRGB color gamut.
      Returns:
      the RGBA color value.
      Throws:
      DOMException - INVALID_ACCESS_ERR: if this value can't return a RGB color value (either is not a COLOR, not a typed value, or clamp is false and the color does not map into the -implicit- sRGB color space).
      NOT_SUPPORTED_ERR: if the conversion needs device color space information to be performed accurately.

    • toLABColorValue

      public LABColorValue toLABColorValue() throws DOMException

      toLABColorValue in class ColorValue
      Returns:
      the converted LABColorValue.
      Throws:
      DOMException - INVALID_STATE_ERR if the components cannot be converted.

    • toLCHColorValue

      public LCHColorValue toLCHColorValue() throws DOMException
