Printing labels over images

How-to
1

Description

There is a full screen with multiple images
(About 50 image files)

I would like to upload a separate label over that image
LABEL will be called from lv_task.

When this happens, reset the full screen buffer to output LABEL.
(Opening and closing image files is repeated indefinitely)
The program is heavy

Is there a way to update the LABEL value while keeping the screen composed of images as the background?

All images and LABEL are created with lv_scr_act()

Ex) lv_label_create (lv_scr_act (), NULL)
lv_img_create (lv_scr_act (), NULL)

This is an infinite loop of open and close files.

If you have plenty of RAM you can render the images into an screen sized lv_canvas object.

This way updating the labels is fast, as the canvas already stores the rendered images.
