My set up is gmic 2.0.0 (a very old version I compiled myself) and a dual core old computer.
I would like to get help with 2 questions I got, please.
parallel is present the output is like ‘split’? Just like if
gmic splits the image and sends the pieces to each core and once finished they are just “glued” together.
How to stop it from “putting” a “line” in the middle of the picture?
Basically is with any filter, if I select the processing to be done with 2 cores at the same time. It does takes half the time to get a result, compared with a single core but is not the same.
This is the image I’m processing with a single core.
If two cores are used, a “line” (or the “boundary of each slice”) is shown in the middle of the picture (check mouth and nose).
