Function Documentation

void clip_data_free

(

lives_clip_data_t *

)

free clip data - this should be called for each instance before unloading the module

lives_clip_data_t* get_clip_data	(	const char *	URI,
		lives_clip_data_t *
	)

pass in NULL clip_data for the first call, subsequent calls (if the URI, current_clip or current_palette changes) should reuse the previous value. If URI or current_clip are invalid, clip_data will be freed and NULL returned.

plugin may or may not check current_palette to see if it is valid

boolean get_frame	(	const lives_clip_data_t *	,
