Generate Images from DXF file failed: Image export failed. Parameter is not valid

I need to generate images from a DXF. I use the following code to generate the images:

The Layouts is a string array: “L1A3”, “L2A3”

var menoryStreams = new List<MemoryStream>();
            customPlanStream.Position = 0;
            using (var cadImage = (CadImage) Aspose.CAD.Image.Load(customPlanStream))
                foreach (var layout in layouts)
                    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 }
                    var imageOptions = new JpegOptions
                        VectorRasterizationOptions = rasterOptions,
                        ColorType = JpegCompressionColorMode.Grayscale,

                    var output = new MemoryStream();
                    cadImage.Save(output, imageOptions);
                    output.Position = 0;
                customPlanStream.Position = 0;

                return menoryStreams;

And give me the following error:
Image export failed. Parameter is not valid
error.png (63.6 KB)

The plan is: (1.6 MB)
