Draw Shapes With ImageSharp

A sample application that demonstrates the core vector drawing capabilities of ImageSharp.Drawing. Each example renders shapes to an Image<Rgba32> using the DrawingCanvas API and saves the result as a PNG file in the Output/ directory.

What it demonstrates

  • Stars — Filled and outlined star polygons with varying point counts, inner/outer radii, line join styles (miter, round, bevel), and dashed outlines with different line caps.
  • Clipping — Rectangle-on-rectangle clipping using IPath.Clip().
  • Path building — Constructing complex shapes with PathBuilder, including multi-figure paths (a V overlaid with a rectangle) and an hourglass shape.
  • Curves — Ellipses via EllipsePolygon and cubic Bezier arcs via CubicBezierLineSegment.
  • Text as paths — Converting text to vector outlines using TextBuilder.GeneratePaths() with system fonts, including text laid out along a curved path.
  • Serialized glyph data — Rendering OpenSans letter shapes ('a' and 'o') from serialized coordinate data as ComplexPolygon instances.
  • Canvas API — Fill for solid backgrounds and shape rendering via ProcessWithCanvas.

Running

dotnet run --project samples/DrawShapesWithImageSharp -c Debug

Output images are written to the Output/ directory, organized into subdirectories by category: Stars/, Clipping/, Curves/, Text/, Drawing/, Letter/, and Issues/.
