Paint brush requires large movement before stroke begins — Wacom Intuos M tablet

Support

Operating system: Windows
Slicer version: 5.10.0

When using the Paint effect in Segment Editor with a Wacom Intuos M tablet on Windows, the brush requires a large physical movement before it starts painting. A short movement is treated as a single click. With a mouse this doesn’t happen. Already tried: slicer.app.startDragDistance = 1, effect.setMinimumPaintPointDistance(0), effect.setDelayedPaint(False), Windows Ink off, Wacom driver settings adjusted where possible. The threshold appears to be in the C++ Paint effect and is not reachable from Python.

I use the same tablet as you and encounter this problem for manual segmentation. Would love to hear any solutions to this (other than manually removing the over-segmented area!)

There is no such property as startDragDistance and I’m not sure how you got the effect. Anyway, the correct code snippet (from this post):

paint=slicer.modules.segmenteditor.widgetRepresentation().self().editor.effectByName("Paint")
paint.delayedPaint=False
paint.minimumPaintPointDistance=3
