cv2.error: OpenCV(3.4.17) :-1: error: (-5:Bad argument) in function ‘imwrite’

Overload resolution failed:

  • Can’t parse ‘params’. Sequence item with index 3 has a wrong type
  • Can’t parse ‘params’. Sequence item with index 3 has a wrong type

This is the wrong statement

cv2.imwrite(outputName+’.jpg’,polar_image,[int(cv2.IMWRITE_JPEG_QUALITY), 100]+[int(cv2.IMWRITE_JPEG_OPTIMIZE), True])

i try to fix it in this way

params = [cv2.IMWRITE_JPEG_QUALITY, 100, cv2.IMWRITE_JPEG_OPTIMIZE, 1]
cv2.imwrite(outputName+’.jpg’,polar_image, params)

here the new error

Can anyone help me, thanks

it doesn’t like the True because that’s a bool and it expects a list of int.

give it 1 instead.

thanks bro i got it :grinning: :grinning:
