Abstract:
1. A method of rendering a sequence of graphical objects where two or more different renderers are available and one of the renderers is designated as a currently-used renderer, said method comprising the steps of: receiving a current object in the sequence of graphical objects; adding the current object to a set of recently-received objects; checking whether any one of a predetermined group of patterns of objects is present in the set, each pattern having an associated indication of the suitability of the available renderers for the pattern, the suitability being dependent on a time taken to render the pattern; determining a suitable renderer from the available renderers using a pattern and associated indication identified in said checking step; switching from the currently-used renderer to the suitable renderer if the suitable renderer is different to the currently-used renderer; and rendering the current object using the determined renderer to at least one of a memory and an output device, wherein the steps are performed on a computer.
