Sometimes there is a need to turn a completed artwork back to a line drawing state to edit it again.
It is convenient to use “History retrieval function” in such case.
The “History retrieval function” allows you to save the past state of an artwork as an IPV file while playing the time-lapse video of it.
Select the ① Play button of an artwork to play the time-lapse video.
Tap the ①︙ button at the point you want to save at and select ② “Save Artwork at This Point”.
An IPV file at the selected time of playback will be saved.
IPV files are saved in My Gallery and can be edited.
