Question: Adding transparent rgba value to penColor

[SimonPaidla]

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.

Sorry I am away from my computer for the weekend so I am unable to test this but my guess is that the issue is how signature_pad draws each line segment to the canvas. This happens for speed. you could redraw the whole canvas on move but for long signatures that would become very slow.

This is actually the same issue I ran into for #771. As of now I don't have a good solution
