Contains configuration items related to the Impress application. Contains a list of implementation names for each canvas service. Tried in order of appearance List of implementation names. List of implementations that are hardware-accelerated. List of implementations that do anti-aliasing. Contains config entries for the DirectX-based implementation of the XCanvas interface. Sequence of 8 integers per device/driver combination, that uniquely mark them as not being compatible with the DirectX9 canvas implementation. If you have trouble with your graphic adapter, and want to add it to the blacklisting, set BlacklistCurrentDevice below to false. After running the Impress slideshow once, your card identification has been added to the list. 0 Indicates whether the current DirectX device ids should get blacklisted. When true, a running DXCanvas will write a DeviceBlacklist entry, and refuse to run on that device subsequently. false If present, limits the size of the textures that get requested from the DX runtime. If not present, textures of the maximal size that is advertised by the driver are used. This value has absolutely nothing to do with the size of primitives that can be rendered, both concepts are independent from each other. The underlying reason for this config item is the fact that several card/driver combinations expose bugs, when running them with their maximum texture size. 2048 List of preferred implementation names, for each given canvas service. When true, force canvas factory to use the last entry of the respective preferred services lists. This entry should represent a safe, works-always implementation, ready to serve as a fallback. false When true, suggest canvas factory to use a canvas service listed in the AcceleratedImplementations lists. true When true, suggest canvas factory to use a canvas service listed in the AntialiasingImplementations lists. true
