PreloadCodecsList # get (RasterCodecs)
The current preload codecs list. The default value is FAX,CMP,TIF,PNG,BMP
.
Use this property before calling PreloadCodecs if you wish to get the current setting for the preload codecs list before changing it.
The preload codecs list contains the list of fixed and cached codecs.
The fixed codec count can be obtained from FixedPreloadCodecs.
The cached codec count can be obtained from CachedPreloadCodecs.
