Dwg not properly converted to PNG using Aspose.CAD (C#)

Aspose.CAD Product Family

Hi.
After using Aspose.CAD, I want to buy.
I downloaded Aspose.CAD and converted dwg file to image.
The image file is converted as shown below.

conic_pyramid_raster_image_out.png (22.5 KB)

What is solution?

The source is shown below.
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog ofd = new OpenFileDialog(); // 파일 탐색기 창 객체 생성

        // 파일 탐색기 Open
        if (ofd.ShowDialog() == DialogResult.OK)
        {
            // The path to the documents directory.
            // string MyDir = RunExamples.GetDataDir_ConvertingCAD();
            // string sourceFilePath = MyDir + "conic_pyramid.dxf";

            string MyDir = @"D:\dwg파일\toImage\";
            string sourceFilePath = ofd.FileName;

            using (Aspose.CAD.Image image = Aspose.CAD.Image.Load(sourceFilePath))
            {

                // Create an instance of CadRasterizationOptions
                Aspose.CAD.ImageOptions.CadRasterizationOptions rasterizationOptions = new Aspose.CAD.ImageOptions.CadRasterizationOptions();

                // Set page width & height
                rasterizationOptions.PageWidth = 1200;
                rasterizationOptions.PageHeight = 1200;
                rasterizationOptions.AutomaticLayoutsScaling = true;
                rasterizationOptions.NoScaling = false;
                // color
                rasterizationOptions.BackgroundColor = Aspose.CAD.Color.Beige;
                rasterizationOptions.DrawType = Aspose.CAD.FileFormats.Cad.CadDrawTypeMode.UseDrawColor;
                rasterizationOptions.DrawColor = Aspose.CAD.Color.Blue;
                // Aspose.CAD.CharacterSet.Hangeul

                // Create an instance of PngOptions for the resultant image
                Aspose.CAD.ImageOptionsBase options = new Aspose.CAD.ImageOptions.PngOptions();

                // Set rasterization options
                options.VectorRasterizationOptions = rasterizationOptions;
                MyDir = MyDir + "conic_pyramid_raster_image_out.png";

                // Save resultant image
                image.Save(MyDir, options);
            }
        }
    }

Thank you.

@softzion,

Can you please share source file that you are using on your end so that i may test that with code and help you out.

Hi.

Look at the attachment.AsposeProject.zip (9.6 MB)

There is also a dwg file in the AsposeProject\AsposeProject\bin\Debug folder.

Thank you.

@softzion,

I have worked with the file shared by you and have been able to observe the issue specified. An issue with ID CADNET-779 has been created in our issue tracking system to further investigate and resolve the issue. This thread has been linked with the issue so that you may be notified once the issue will be fixed.

The issues you have found earlier (filed as CADJAVA-467) have been fixed in this update.

@softzion,

We have tried other options to make text better (rasterizationOptions.Quality.Text, rasterizationOptions.Quality.TextThicknessNormalization) but no success. The only way to improve it is to increase canvas size. In the attached project it is

rasterizationOptions.PageWidth = image.Width + 2000;
rasterizationOptions.PageHeight = image.Height + 2000;

and setting bigger values

rasterizationOptions.PageWidth = image.Width + 3000;
rasterizationOptions.PageHeight = image.Height + 3000;

makes text readable.
