Closed Python: Slider

[alchemist_19]

Paano po mag add ng slider or bar slide para ma adjust yung value ng alpha ng dalawang images?
Code:

import cv2
import numpy as np

#Two Images: Lena & Design
lena = cv2.imread("C:/Image Processing/lena/lena.jpg")
design= cv2.imread("C:/Image Processing/lena/birthday.jpg")

#Two images are Same size
design = cv2.resize(design, lena.shape[1::-1])

#Value ng Alpha
dist = cv2.addWeighted(lena, 0.7, design,0.3, 0)

cv2.imshow("Blended Image", dist)
cv2.waitKey(0)
cv2.destroyAllWindows()

OUTPUT:
