Drag a larger brush or disk to classify puncta en masse in 2d viewer #18

Closed karlcz closed 7 years ago

karlcz commented 7 years ago

Users would like to quickly classify multiple adjacent puncta by painting a region coarsely with the mouse. It was suggested that a 5-10 micron diameter disk might be appropriate, and that separate controls to paint positive and negative classification decisions would be useful, i.e. positive via primary/left mouse and negative via secondary/right mouse button drags. An example use case is to quickly paint over an auto-fluorescing skin region or the halo around a nuclei that otherwise looks like many synapse-scale puncta.

Oops, I just submitted an issue at the same time as receiving this. We were thinking the same thing!

I've committed an experimental feature to paint multiple segments via mouse drags.

The UX should be self-explanatory once you try dragging with primary and secondary mouse buttons. A circular region is highlighted in inverted colors beneath the mouse, and all segments in that region get set as either features or non-features depending on which button is held during the drag.

Individual non-dragging clicks still behave as before, but if your mouse is too sensitive it may be difficult to use this feature without accidentally activating the painting mode.

User testing suggested using different radii for the positive and negative paint modes, so it now uses approximately half the radius for the positive mode.
