I checked manim's method. I tried using Zoomed Scene.
from manimlib.imports import *
class test(ZoomedScene):
CONFIG = {
"zoom_factor": 0.3,
"zoomed_display_height": 1,
"zoomed_display_width": 6,
"image_frame_stroke_width": 20,
"zoomed_camera_config": {
"default_frame_stroke_width": 3,
},
}
def construct(self):
dot = Dot().shift(UL * 2)
image = ImageMobject(np.uint8([[0, 100, 30, 200], [255, 0, 5, 33]]))
image.set_height(7)
frame_text = TextMobject("Frame", color = PURPLE).scale(1.4)
zoomed_camera_text = TextMobject("Zoomed camera", color = RED).scale(1.4)
self.add(image, dot)
zoomed_camera = self.zoomed_camera
zoomed_display = self.zoomed_display
frame = zoomed_camera.frame
zoomed_display_frame = zoomed_display.display_frame
frame.move_to(dot)
frame.set_color(PURPLE)
zoomed_display_frame.set_color(RED)
zoomed_display.shift(DOWN)
zd_rect = BackgroundRectangle(zoomed_display, fill_opacity = 0, buff = MED_SMALL_BUFF)
self.add_foreground_mobject(zd_rect)
unfold_camera = UpdateFromFunc(zd_rect, lambda rect: rect.replace(zoomed_display))
frame_text.next_to(frame, DOWN)
self.play(ShowCreation(frame), FadeInFrom(frame_text, direction = DOWN))
self.activate_zooming()
self.play(self.get_zoomed_display_pop_out_animation(), unfold_camera)
zoomed_camera_text.next_to(zoomed_display_frame, DOWN)
self.play(FadeInFrom(zoomed_camera_text, direction = DOWN))
scale_factor = [0.5, 1.5, 0]
self.play(frame.scale, scale_factor, zoomed_display.scale, scale_factor, FadeOut(zoomed_camera_text), FadeOut(frame_text))
self.wait()
self.play(ScaleInPlace(zoomed_display, 2))
self.wait()
self.play(frame.shift, 2.5 * DOWN)
self.wait()
self.play(self.get_zoomed_display_pop_out_animation(), unfold_camera, rate_func = lambda t: smooth(1 - t))
self.play(Uncreate(zoomed_display_frame), FadeOut(frame))
self.wait()
