imwrite supports writing multi-page tiffs by checking whether InputArray is a MatVector
|
std::vector<Mat> img_vec; |
|
if (_img.isMatVector() || _img.isUMatVector()) |
|
_img.getMatVector(img_vec); |
However, on python it can never be done as the binding generator does not try creating vector_Mat for InputArray - just Mat and UMat.
Steps to reproduce
import cv2
img = cv2.imread("doc/opencv-logo.png")
cv2.imwrite("multi.tiff", [img, img, img])Issue submission checklist
