Yeah, all depends if the lines are on a transparent layer. From a similar post a couple of days ago https://i.imgur.com/39kVCLB.mp4

Quote: All the green lines are in one layer, except for a few which are in another layer (I also want to change these ones)...snip...I only want to change the pixels that make up the lines.

For the 'other layer' Again providing it is lines on a transparent layer, make a selection of what needs changing, then as above.
