59 <p>AcquireAuthenticCacheView() acquires an authentic view into the pixel cache. It always succeeds but may return a warning or informational exception.</p>
86 <p>AcquireVirtualCacheView() acquires a virtual view into the pixel cache, using the VirtualPixelMethod that is defined within the given image itself. It always succeeds but may return a warning or informational exception.</p>
157 <p>GetCacheViewAuthenticPixels() gets pixels from the in-memory or disk pixel cache as defined by the geometry parameters. A pointer to the pixels is returned if the pixels are transferred, otherwise a NULL is returned.</p>
345 <p>GetCacheViewVirtualPixels() gets virtual pixels from the in-memory or disk pixel cache as defined by the geometry parameters. A pointer to the pixels is returned if the pixels are transferred, otherwise a NULL is returned.</p>
377 <p>GetOneCacheViewAuthenticPixel() returns a single pixel at the specified (x,y) location. The image background color is returned if an error occurs.</p>

526 <p>QueueCacheViewAuthenticPixels() queues authentic pixels from the in-memory or disk pixel cache as defined by the geometry parameters. A pointer to the pixels is returned if the pixels are transferred, otherwise a NULL is returned.</p>
589 <p>SetCacheViewVirtualPixelMethod() sets the virtual pixel method associated with the specified cache view.</p>
610 <dd>the virtual pixel method. </dd>
616 <p>SyncCacheViewAuthenticPixels() saves the cache view pixels to the in-memory or disk cache. It returns MagickTrue if the pixel region is flushed, otherwise MagickFalse.</p>
