Okay, if I rasterize the layer then I can select and fill it to get the look I want. But it's problematic, once rasterized I can't edit nodes, and I have to rasterize, select and fill every time I make an addition.
I'm making some custom assets for a program called Dungeondraft, it allows you to quickly make battle maps for role playing games like Dungeons and Dragons. It has an old school style with 256 dpi and no AA, hence the desire for pixelated lines. And what I'm making specifically is spiderwebs, hence the desire for nice curves.
Threshold adjustment layer might work, but I'm unable to get right effect without losing the color. If it was just black and white it would be the best option I've found so far.
I'm inserting a few images. First was done by hand with pixel tool, right look but the curves aren't nice.
Second was done with pen tool, nice curves but it's not pixelated.
Third was done with pen tool then rasterize, select and fill. I have to adjust thickness of the lines but the effect is right.
They have white backgrounds but the final product won't, and the color doesn't seem right on the uploaded images but they should still help show what I'm talking about.
I'm still hoping there's a way to get the pen tool to just output pixelated lines.
Thanks a lot for your guys' help so far!
