How to create a motorway route brush?

[fwyplanner]

Consider road maps where motorway routes appear. Let's say the following images:

(motorway is represented by a blue-white-blue line)

(a bit more complex, motorway is represented by a black-orange-black-orange-black complex line)

Is it possible to create a brush in paint.net such that we can directly draw something like that?

Remember, the direction in which the pattern is drawn should always instantly change in synergy with the direction in which the brush tool is drawn.

Thanks.

Remember, the direction in which the pattern is drawn should always instantly change in synergy with the direction in which the brush tool is drawn.

This is not currently possible. However, as usual there are workarounds

If you were to define the path of the motorway as a cut out on an otherwise opaque layer, then it would be possible to follow the path whilst drawing on a layer underneath it.

If you were to download the custom brushes plugin, you could define yourself a large(ish) radial brush where the pattern radiates out from the centre point.

Putting it all together: the radial brush is used on the lower layer. You see the brush peeping through the cut out in the upper layer. Careful movement of the brush will change the visible pattern depending on where the centrepoint of the brush is situated in relation to the motorway path.

If I get time tonight I might post a followup image. Good luck.

This doesn't involve the use of a brush.

Use the Line/Curve tool on new layers to lay out the roadway in the center color.

Use Outline Object plugin to to add the outer colors.

Thank you for both replies.

Indeed, the Outline Object plugin is actually really great for this purpose!

Thank you, Sarkut!
