Brush edit problem

I want to create a straight line that's two pixels wide. There's a brush that's 1px, and another that's 3px, so I created a new brush, made it a square one and selected a radius of 1.0px. If I do this, the brush appears to be 3px in width.

So I tried various values. 0.7px radius still gives me a brush that is 3px wide. However, 0.6px radius gives me one that is 1px wide. I don't seem to be able to find any setting that makes it 2px wide, and neither can I understand the relationship between "radius" and the actual size of the brush. The same thing happens with higher values - anything from 0.7 up to 1.6 gives me a brush that's 3px wide, then at 1.7 it jumps to 5 pixels.

Is it impossible to have a brush that is an even number of pixels wide, and if so, why?

Better use a path and use the "stroke path" option in the paths dialog! You can enter a specific value there, and you can use different line types too (from solid to dashed and/or dotted). pretty cool...

Hope that helps ;)

No, but it may be impossible to have an even sized 'virtual' brush, which is the type you're editing.
You may need to create a 2x2 grayscale image filled with black* and save it with a 'gbr' extension to your brushes directory.(then refresh the brushes dialog)

* or is it white? one of those two.

Ah OK - many thanks for both your suggestions :)

Why not use the 1x1 with scaling set to 2?
