nsgif_data_complete()

void fl::third_party::nsgif_data_complete

(

nsgif_t *

gif

)

Tell libnsgif that all the gif data has been provided.

Call this after calling nsgif_data_scan with the the entire GIF source data. You can call nsgif_data_scan multiple times up until this is called, and after this is called, nsgif_data_scan will return an error.

You can decode a GIF before this is called, however, it will fail to decode any truncated final frame data and will not perform loops when driven via nsgif_frame_prepare (because it doesn't know if there will be more frames supplied in future data).

Parameters

[in]

gif

The nsgif_t object.
