Hi, im trying to create a line, but without the blurry edges.

when i use the line in vector, the blurry edges occur, but when i use a normal paint layer, there is no blurry edge.
I need there to be no blurry edge in the vector layer, because I use vector to resize my designs.

Someone asked for that on the irc channel, too, yesterday, but no, that is not possible with Krita's vector layers.

If you want to reduce the visual impact of the anti-aliasing (which is what causes the 'blurring') you can increase the dpi of your image. Try scaling it to 200% and that will reduce the apparent extent of the antialiased edges. Krita will always show you what the final rendered output will look like and this is determined by the image resolution.
