How can you create neon lines in gimp?

Answer 1

I assume you are trying to create a solid bar or rounded line that has a glowing neon effect, though this simple strategy can be applied to virtually any one-color design.

To begin, open a blank document. Create a new layer filled with transparency. Draw your desired line. You can use any sort of one-color image, but I prefer to draw the lines with the paintbrush. It's simple and effective.

Once you have achieved your desired outline, use the menus at the top and select "Filters". Select "Alpha to Logo" in the drop-down menu and then select one called "Neon".

A dialogue box will appear. Simply fill in your desired glow and background colors and click OK.

Voila. This will render your neon line.

I hope this has helped you. =]
