Examples

Create Graphics Path from Path Resources in TIFF image.

using (var image = (TiffImage)Image.Load("Bottle.tif"))
{
    // Create the GraphicsPath using PathResources from TIFF image
    var graphicsPath = PathResourceConverter.ToGraphicsPath(image.ActiveFrame.PathResources.ToArray(), image.ActiveFrame.Size);
    var graphics = new Graphics(image);

    // Draw red line and save the image
    graphics.DrawPath(new Pen(Color.Red, 10), graphicsPath);
    image.Save("BottleWithRedBorder.tif");
}

Create Path Resources using Graphics Path.

static void Main(string[] args)
{
    using (var image = (TiffImage)Image.Load("Bottle.tif"))
    {
        // Create rectangular Figure for GraphicsPath
        var figure = new Figure();
        figure.AddShape(CreateBezierShape(100f, 100f, 500f, 100f, 500f, 1000f, 100f, 1000f));

        // Create GraphicsPath using our Figure
        var graphicsPath = new GraphicsPath();
        graphicsPath.AddFigure(figure);

        // Set PathResources using GraphicsPath
        var pathResouze = PathResourceConverter.FromGraphicsPath(graphicsPath, image.Size);
        image.ActiveFrame.PathResources = new List<PathResource>(pathResouze);

        // Save the image
        image.Save("BottleWithRectanglePath.tif");
    }
}

            yield return new PointF(coordinates[coordinateIndex], coordinates[coordinateIndex + 1]);
