Describe the feature and motivation Every now and then i want to convert single pixel values. that includes channels, depth, colorspace, scaling and container type (e.g.: VecN and Scalar). at the moment that is not possible with opencv using a single function. i would like to have such...

I noticed a change since Pillow 7.2.0 when I try to convert a PIL RGBA image into an OpenCV image without alpha channel. Since version 7.2.0, my PIL image is rendered as an opaque square when I convert it. To illustrate my issue, here is a simple script: import PIL import cv2 impor...
. In case of multi-channel arrays, the function processes each channel . independently. When the output is not 8-bit, the operation can be . emulated by calling the Mat::convertTo method (or by using matrix . expressions) and then by calculating an absolute value of the result. ...
