Question: Adding transparent rgba value to penColor

Hello everyone,

I have the following problem: I would like to use a transparent pen color to highlight texts (e.g., rgba(255,0,0,0.3)). As shown in the image, the bottom two lines (with rgba color value) do not deliver the desired result. Unfortunately, I couldn't gather from the documentation whether and how I can solve the problem myself, which is why I'm asking here.

• Is there an option to prevent these dots from appearing when using transparent color (example line 2/3 from the image)?
• Is there an option to prevent the lines from becoming "thicker" when redrawing with transparent color? (example line 3 from the image)

I tried experimenting with the options:

• dotSize
• throttle
• minDistance.

But none of the changes produce a good result

Thank you in advance for your help.
