Declaration

procedure SaveSnapshot(Stream: TStream; SaveCache: Boolean = True; Compressed: Boolean = False; SaveParams: Boolean = False);
Description
Saves the image, cache data, text and dimensions of all frames to the specified stream or file.
This can be used to create caching mechanism, like Windows .db files, to load quickly an entire directory of images.
| Value | Description |
