Description
Loads a thumbnail specified by the AFileName parameter and with specified dimensions from a file.
The AFitWidth parameter specifies the width of the thumbnail.
The AFitHeight parameter specifies the height of the thumbnail.
UseEmbedded indicates the use of an existing thumbnail. If UseEmbedded is True and AFileName has a thumbnail, then the existing thumbnail of the file is used. In this case, AFitWidth and AFitHeight are ignored. If no thumbnail is found, then one is generated with the specified size. If UseEmbedded is False, a thumbnail is generated with the specified size.
Note: Before loading from file, call a TBitmap constructor if the bitmap is not initialized by other components. If the file is not found or it does not exist, the new TBitmap will be empty.
