void SEQ_transform_handle_xlimits	(	Sequence *	seq,

Use to impose limits when dragging/extending - so impossible situations don't happen. Cant use the SEQ_LEFTSEL and SEQ_LEFTSEL directly because the strip may be in a meta-strip.

◆ SEQ_transform_offset_after_frame()

void SEQ_transform_offset_after_frame	(	Scene *	scene,

Move strips and markers (if not locked) that start after timeline_frame by delta frames

Parameters

scene	Scene in which strips are located
seqbase	ListBase in which strips are located
delta	offset in frames to be applied
timeline_frame	frame on timeline from where strips are moved
