 | | Viewers are expected, however, to composite every foreground layer against a fresh copy of the background, when the framing mode given in the FRAM chunk is 3, and to composite the first foreground layer of each subframe against a fresh copy of the background, when the framing mode is 4. |
 | | When the FRAM parameters are changed, the new parameters affect the subframe that is about to be defined, not the one that is being terminated by the FRAM chunk. |
 | | Also, decoding a FRAM chunk, when the current framing mode requires a background layer (framing mode is 3 or 4) and none of the above have already caused the background layer to be inserted since the previous FRAM chunk. |
