stroking path with 1 pixel width brush is semiopaque

I selected a 1 pixel thick brush to stroke the drawn path onto an image. When I stroked the path, the color of the stroke appears semi transparent. Is there a way to make it appear completely solid. Thanks

Thanks but Cloning does not explain why the drawn stroke does not appear solid, it appears semitransparent also I am not trying to remove a feature.

You could turn off antialiasing (extension of the stroke dialog under "line style") or use the pencil as "paint tool" there with a 1 pixel brush, these two methods look equivalent to me. You might have noticed that you have full color pixels where the path goes straight across a pixel, but less when the pixel is only touchedm this is due to the antialiasing that's on by default.

This will give a fully colored, 1-pixel line: -------------------------
| x-|---|---|---|---|-x |
-------------------------

This will give a 50% colored, 2-pixel line: -------------------------
| | | | | | |
--x-------------------x--
| | | | | | |
-------------------------

I hope this helped a bit to understand the problem.

Hi,

Add that 50% pixel intensity does not have to match 50% light intensity (gamma), and the problem becomes more obvious.

Thanks, antialiasing was the problem. Appreciate the explanation.
