Methods

• MaskNode (source = null, mask = null, mask_mode = null)

  Creates a GskRenderNode that will mask a given node by another. The

  • @mask_mode determines how the 'mask values' are derived from the colors of the @mask. Applying the mask consists of multiplying the 'mask value' with the alpha of the source.
  • @p source is The source node to be drawn.
  • @p mask is The node to be used as mask.
  • @p mask_mode is The mask mode to use.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asRenderNode ()

  Wraps this handle as RenderNode.

  • @r A RenderNode object.

• get_mask ()

  Retrieves the mask GskRenderNode child of the @node.

• get_mask_mode ()

  Retrieves the mask mode used by @node.

• get_source ()

  Retrieves the source GskRenderNode child of the @node.
