Antialising for Strokethickness >= 2

Answered

Hello!

I’ve created a Scichart project. I have a problem using antialiasing property with FastLineRenderableSeries: it works perfect when strokethickness property is set to 1, but when I set strokethickness to value that is greater than 1, changing antialiasing property doesn’t affect renderableseries.

How can I fix this?

Thanks in advance.

Hi Vyacheslav,

Have you seen our article High Quality vs. High Speed vs. DirectX Renderer Plugins?

This talks about the three renderer plugins in SciChart and their strengths / weaknesses.

It sounds to me like you are using the HighSpeedRenderSurface, which uses integer coordinates and fixed point arithmetic. Unfortunately its impossible to correctly anti-alias when lines are thicker than one pixel and in this mode.

Fortunately both the HighQualityRenderSurface and the Direct3D10RenderSurface support antialiasing at higher stroke thicknesses.
