The stroke is cut off or cropped if filter (e.g. blur) applied
Summary:
The outline of an object made of strokes is cut off at the geometry (middle or vertex) of the stroke instead of at the thickness of the stroke. Converting stroke to path (so it doesn't have a stroke, but uses fills instead) fixes this as the filter region is relative to the geometric bounding box (see fixed file).
Steps to reproduce:
- open Inkscape
- Choose "Draw freehand lines"
- Draw a 4-sided object with wavy edges, drawing the four edges separately, making sure the corner is red before starting or ending a line, so they continue where the last line left off.
- Click a color to set the fill
- Set stroke style thick such as 4 mm
- Add a small blur
Note in stable releases (1.0.1 and earlier), it is easy to accidentally add a blur when scrolling (as has occurred here, see #4197 (closed))
What happened?
The edges are cut off as the automatic filter region does not take stroke-width into account.
What should have happened?
Filter region should account for the stroke-width, so the entire thickness of the stroke is displayed.
