Hello!
I have an image and I need a black image with same dimensions as the first one. The second image needs to be all black. Please, is it possible to create a black image specifying its dimensions or to paint the image I have with black color?
Thanks for the help!

Thank you! I tried to use this function, but it didn`t work. I think I put the wrong value to modify everything to black.
