In WPF, you could override the OnDraw to create a custom geometry to render as the 'wet' ink, although it increases latency quite a bit since you're not using the geometry provided and already calculated. I'm wondering if it is possible to achieve something similar in UWP. Suppose I wanted my pen to stroke to be jagged and zig-zagy. The 'dry' ink would be simple to implement with custom drying and all, but is there any way for my 'wet' ink to achieve this effect as well?
Win2D has capabilities to render ink, you could use CanvasControl to render ink strokes with InkCanvas.
The CanvasControl has a Draw event, you could collect the 'wet' ink strokes and render it in this event.
There’s an official Win2D sample called ‘InkExample’, if you want, you could check it.
