My problem is, how can I thicken and darken very thin/faint lines of
scanned
images?


filters->distorts->valuepropagate, set to "more black" and about 0.23,
followed by colours->curves, and then filters->enhance->sharpen
(unsharp mask) with the lower slider about 3 times the value of the
upper one - increase until the lines go back.
