  • Constructor Details

    • SVGFeTurbulenceElementBridge

      public SVGFeTurbulenceElementBridge()
      Constructs a new bridge for the <feTurbulence> element.
  • Method Details

    • getLocalName

      public String getLocalName()
      Returns 'feTurbulence'.
    • createFilter

      public Filter createFilter(BridgeContext ctx, Element filterElement, Element filteredElement, GraphicsNode filteredNode, Filter inputFilter, Rectangle2D filterRegion, Map filterMap)
      Creates a Filter primitive according to the specified parameters.
      Parameters:
      ctx - the bridge context to use
      filterElement - the element that defines a filter
      filteredElement - the element that references the filter
      filteredNode - the graphics node to filter
      inputFilter - the Filter that represents the current filter input if the filter chain.
      filterRegion - the filter area defined for the filter chain the new node will be part of.
      filterMap - a map where the mediator can map a name to the Filter it creates. Other FilterBridges can then access a filter node from the filterMap if they know its name.
    • convertBaseFrenquency

      protected static float[] convertBaseFrenquency(Element e, BridgeContext ctx)
      Converts the 'baseFrequency' attribute of the specified feTurbulence element.
      Parameters:
      e - the feTurbulence element
      ctx - the BridgeContext to use for error information
    • convertStitchTiles

      protected static boolean convertStitchTiles(Element e, BridgeContext ctx)
      Converts the 'stitchTiles' attribute of the specified feTurbulence element.
      Parameters:
      e - the feTurbulence element
      ctx - the BridgeContext to use for error information
      Returns:
      true if stitchTiles attribute is 'stitch', false otherwise
    • convertType

      protected static boolean convertType(Element e, BridgeContext ctx)
      Converts the 'type' attribute of the specified feTurbulence element.
      Parameters:
      e - the feTurbulence element
      ctx - the BridgeContext to use for error information
      Returns:
      true if type attribute value is 'fractalNoise', false otherwise
