I came across this map and would like to replicate the textured styling found along the borders. I'm starting with a multipart polygon but my process has perhaps too many steps. I'm using QGIS 2.8.2.
- Processing algorithm: Convert original polygon to lines
- Processing algorithm: Fixed distance buffer
- Clip buffer using the original multipart polygon
- Style the clipped buffer with Line Pattern Fill, adjusting transparency, line width, etc.
Here is my output:
Any ideas on how to achieve this effect in fewer steps? I sense I'm overlooking an option like color burst, but where you can use a line pattern as a fill. Or, perhaps there's a way to do an inverted or negative buffer, which would save me the clipping step.
Update: Buffers with negative values create smaller versions of the original multipart polygons, not a sort of boundary area. (Note: I'm using Vector/Geoprocessing/Create Buffer.)
I think the buffer layer itself does need to be clipped too, presuming you have outermost boundaries to consider.
