Ok I know what you are doing. Gmic input has various options. You are on active layer(default) that gives the black image.

Change it to Active and Below as this https://i.imgur.com/qtIEFWF.jpg

Hi. 
I've just tried. It works. But the result is not satisfactory. 
I remember that 3 years ago I did this, probably with another plugin, it was awesome
but I've
really forgot what it is and unable to find out from my older entries. 
Would you recommend a few of other plugins for me to see if I will
remember which one I used??
