How i can open PNG w alpha channel, if he is white

Question

I have a lot images like this: Screenshot from ImageMagick

When I open it image in cv2, PIL I see only white canvas without any alpha channel

I started looking for the difference between these files, and those who open correctly and in ImageMagick saw this line Alpha: srgba(255,255,255,0) #FFFFFF00 screenshot

Valid files have Alpha: srgba(0,0,0,0) #00000000

UPD. The question is closed. Files must be opened with the flag IMREAD_UNCHANGED

Answer 1

I should have written like this

cv2.imread('file.png', cv2.IMREAD_UNCHANGED)
