Alpha (opacity) is applying for previous strokes about sketch.js

[Lewiscowles1986]

is alpha increasing, or are you noticing that when 30% of colour x is applied to 30% colour x it makes 60% opacity (thats how it works, it's not a bug if this is the complaint and would require modifcation to work your way by clearing the area to 0% opacity, then drawing in the required opacity). If I have misunderstood please feel free to ignore

I want to draw a stroke with some opacity consistently. will you please explain how to modify that functionality. thanks.

srinu I just did you need to firstly write / wipe area to transparent, then apply your colour, this will stop opacity building up and keep it constant, but it is a change request not an issue...
