Distorted Images in aspose version 21.3.0

Hello, I was working with ASPOSE CAD version Image generation in ASPOSE 21.2.0 and the images that I was generating from a DXF hiding a layer was as follows:
capture1.PNG (37.6 KB)
capture2.PNG (25.5 KB)

But I updated to the latest version 21.3.0 and it generates distorted images.
capture3.PNG (25.1 KB)
capture4.PNG (20.9 KB)

The dxf file is: plan.zip (1.6 MB)

My code is:
using (var cadImage = (CadImage) Aspose.CAD.Image.Load(customPlanStream))
{
var rasterOptions = new CadRasterizationOptions
{
PageWidth = 2600F * 3, //cadImage.Width
PageHeight = 2100F * 3, //cadImage.Height
AutomaticLayoutsScaling = true,
ExportAllLayoutContent = true,
DrawType = CadDrawTypeMode.UseObjectColor,
Margins = new Margins() { Top = 0, Bottom = 0 },
Quality = new RasterizationQuality
{
Arc = RasterizationQualityValue.High,
Hatch = RasterizationQualityValue.High,
Text = RasterizationQualityValue.High,
TextThicknessNormalization = true
},
Layouts = new string[] { layout },
Layers = cadImage.Layers.GetLayersNames().Where(l => !l.Equals(“PROSPEKT-EINFÄRBUNG”)).ToArray()
};
var imageOptions = new JpegOptions
{
VectorRasterizationOptions = rasterOptions,
ColorType = JpegCompressionColorMode.Grayscale,
};
var output = new MemoryStream();
cadImage.Save(output, imageOptions);
output.Position = 0;
return output;
}

Thanks for your help!

Hi @mudassir.fayyaz,
Sure, the process is the following:

  • Read a DXF file (The path is displayed in the console)
  • Extract Layouts.
  • Extract the dimensions in the plan.
  • Set dimension values for generate a custom plan with custom dimensions.
  • Generate images from the custom dxf by layouts
  • Export a PDF with the images (The path is displayed in the console).

The file weighs 10MB aprox. so the page recommends use an external link:

Enter and click in download.

Result: plan.pdf (2.2 MB)

As a reminder, the successful result is in the screenshots attached in the main question.
