I have an image (see attachment) which contains a clippingpath with multiple subPaths. One path (Cyan area) ist completely embedded in the area (Magenta) of another. The area of the inner path is not cropped, when I create a mask from the paths, but the other one (Yellow) is.  PathForTest.tif (1,856kb) downloaded 15 time(s).
This one from the tutorial works as expected Code:
using (var reader = ImageReader.Create(@"input.tif"))
using (var bitmap = reader.Frames[0].GetBitmap())
using (var maskBitmap = new Bitmap(bitmap.Width, bitmap.Height, PixelFormat.Format8bppGrayscale, System.Drawing.Color.Black))
using (var graphics = maskBitmap.GetAdvancedGraphics())
{
var grPath = Aurigma.GraphicsMill.AdvancedDrawing.Path.Create(reader.ClippingPaths[0], reader.Width, reader.Height);
graphics.FillPath(new SolidBrush(new GrayscaleColor(255)), grPath);
bitmap.Channels.SetAlpha(maskBitmap);
bitmap.Save(System.IO.Path.GetTempPath() + "result.tif");
}
This is mine and it does not: Code:using (var reader = ImageReader.Create(@"input.tif"))
using (var maskGen = new ImageGenerator(new GraphicsContainer(reader), PixelFormat.Format8bppGrayscale, RgbColor.Black))
using (var graphics = maskGen.GraphicsContainer.GetGraphics())
using (var bitmap = new Bitmap())
{
var graphicsPath = reader.ClippingPaths[0].CreateGraphicsPath(reader.Width, reader.Height);
graphics.FillPath(new SolidBrush(new GrayscaleColor(255)), Aurigma.GraphicsMill.AdvancedDrawing.Path.Create(graphicsPath));
using (var setAlpha = new SetAlpha(maskGen))
{
(reader + setAlpha + bitmap).Run();
bitmap.Save(System.IO.Path.GetTempPath() + "result.tif");
}
}
I can't see the difference. I already tracked it down to the creation of the mask, which is wrong in the way that the blue area is not marked to crop. What do I have to do to correct this issue?

Please try this code: Code:using (var reader = ImageReader.Create("../../../PathForTest.tif"))
using (var maskGen = new ImageGenerator(reader.Width, reader.Height, PixelFormat.Format8bppGrayscale, RgbColor.Black))
using (var drawer = new Drawer())
using (var bitmap = new Bitmap())
{
var graphicsPath = Aurigma.GraphicsMill.AdvancedDrawing.Path.Create(reader.ClippingPaths[0], reader.Width, reader.Height);
drawer.Draw += (sender, e) =>
{
e.Graphics.FillPath(new SolidBrush(new GrayscaleColor(255)), graphicsPath);
};
using (var setAlpha = new SetAlpha(maskGen + drawer))
{
(reader + setAlpha + bitmap).Run();
bitmap.Save("../../../result.tif");
}
}
