Clipping PathsDrawingPipelineTGA

Reads image in JPEG format, converts clipping path to alpha channel and saves to TARGA 32 format.

Code Snippet

using (var reader = ImageReader.Create("Apple.jpg"))
using (var alpha = new Bitmap(reader.Width, reader.Height, PixelFormat.Format8bppGrayscale, RgbColor.Black))
using (var writer = ImageWriter.Create("ConvertClippingPathToTga.tga"))
{
    using (var graphics = alpha.GetGraphics())
    {
        var path = reader.ClippingPaths[0];
        using (var graphicsPath = Path.Create(path, alpha.Width, alpha.Height))
        {
            graphics.FillPath(new SolidBrush(RgbColor.White), graphicsPath);
        }
    }

    using (var setAlpha = new Aurigma.GraphicsMill.Transforms.SetAlpha(alpha))
    {
        Pipeline.Run(reader + setAlpha + writer);
    }
}
