header information is missing from image, after writing using opencv

Question

I am doing complement of an image using open-cv python, while writing the image, open-cv is not writing the header information in the complemented image. my image data are in TIFF format.

i am doing like this...

import cv2 img = cv2.imread("image.tiff", -1) for i in xrange(0, len(img)): for j in xrange(0, len(i)): img[i][j] = 65535-img[i][j] cv2.imwrite("complemented.tif", img)

opencv supports tiff, docs.opencv.org/modules/highgui/doc/… — user3272600

What header info would you like to see? Do you have information in the original image that you want preserved? — Stefan van der Walt

As described in this link, Each TIFF file begins with a image file header which points to one or more image file directories, which contain the image data and image information., header information is required for multi-image TIFF.

Multi-image TIFF is not supported in OpenCV as @Haris mentioned in the comments.

Since, multi-image TIFF is not supported, it is most likely that header information is not read using imread and thus cannot be written using imwrite.

Then what are the other options ??. I want to do the complement a .tif image file.
