For an overview about Renderers, see General Information. For a list of all Renderer functions and related topics, see Renderers.
The renderer attributes are listed in the Renderer Attributes Table. They are set with the PEXChangeRendererExtAttributes function, and also can be specified when a renderer is created with a PEXCreateRendererWithExtAttributes function. The data structures associated with the renderer attributes are in Data Structures for Renderer Attributes.
You must use the "bitmask/value" interface to specify renderer attributes when using the PEXChangeRendererExtAttributes, PEXCreateRendererWithExtAttributes, or PEXGetRendererExtAttributes functions. You specify a bitmask that indicates which attributes you wish to set, change, or get. The size of the bitmask accepted by these functions is two words, as opposed to the single word masks used in older PEXlib functions. This change means that you can no longer pass the bitmask itself in these functions; you must pass a pointer to a multi-word bitmask. Note also, that the definition of the bitmask constants (the PEXRXA* symbols below) are no longer bitmasks, but are shift values. You should now use the PEXSetRendererExtAttributeMask function to set up bitmasks. You complete the "value" portion of the interface by putting the values you want to change in the PEXRendererAttributes data structure.
If a renderer attempts to read a value from a lookup table which has a resource ID of None(0), then the fallback attributes for the lookup table are used, except as noted in the individual descriptions of the lookup tables below. If a renderer attempts to read a value from a name set which has a resource ID of None, then the result is as if the name set exists but is empty. If the renderer's pipeline context attribute contains the resource ID of None, then the default values for the pipeline context are copied to the renderer's pipeline state during renderer initialization. If you wish to modify a reference to a resource to indicate that no resource is to be referenced, use the special resource identifier None.
