v0.28.0

Fixed

• PDF Viewport Capture / PDF Image failed with Method not found: SixLabors.ImageSharp.Image.Loadwhen another installed Grasshopper plugin bundled a newer ImageSharp. Grasshopper loads all plugin dependencies into a single context, so only one version of a library can ever be used and whichever plugin loads first wins. PDF image decoding now uses System.Drawing, so it no longer depends on which other plugins are installed.
• Image failures now report which stage failed (decode / jpeg encode / bmp encode).

Added

• PDF Quick Export and PDF Flat Geometry now accept open curves, which are stroked rather than filled. Previously any curve that was not closed was discarded without notice.
• PDF Flat Geometry accepts a single horizontal line as an element (a rule).

Changed

• Fill Color is no longer required. Supply a fill, a stroke, or both - with nothing supplied you get a 1pt black line. Existing definitions are unaffected.
• Curves that cannot be drawn now warn with a count instead of disappearing silently.
• Clearer errors when geometry has no extent in one axis.

Install

Download the zip for your platform and drop the contents into your Grasshopper Libraries folder.
On Windows, Rhino must be running the .NET Core runtime (SetDotNetRuntime → NETCore → restart).
