获取 DWF 的页面大小和页面尺寸

添加了获取“DWF”文件的页面大小和页面尺寸的功能。

// The path to the documents directory.
string MyDir = RunExamples.GetDataDir_DWFDrawings();
string sourceFilePath = MyDir + "blocks_and_tables.dwf";
string extension = Path.GetExtension(sourceFilePath);
using (DwfImage image = (DwfImage)Aspose.CAD.Image.Load(sourceFilePath))
    {
        foreach (var page in image.Pages)
            {
                var layout = page.Name;
                System.Console.WriteLine("Layout= " + layout);
                using (FileStream fs = new FileStream(MyDir + "layout_" + layout + ".jpg", FileMode.Create))
                {
                    JpegOptions jpegOptions = new JpegOptions();
                    CadRasterizationOptions options = new CadRasterizationOptions();
                    options.Layouts = new string[] { layout };

                    double sizeExtX = page.MaxPoint.X - page.MinPoint.X;
                    double sizeExtY = page.MaxPoint.Y - page.MinPoint.Y;

                    if (page.UnitType == UnitType.Inch)
                    {
                        options.PageHeight = CommonHelper.INtoPixels(sizeExtY, CommonHelper.DPI);
                        options.PageWidth = CommonHelper.INtoPixels(sizeExtX, CommonHelper.DPI);
                    }
                    else if (page.UnitType == UnitType.Millimeter)
                    {
                        options.PageHeight = CommonHelper.MMtoPixels(sizeExtY, CommonHelper.DPI);
                        options.PageWidth = CommonHelper.MMtoPixels(sizeExtX, CommonHelper.DPI);
                    }
                    else
                    {
                        options.PageHeight = (float)sizeExtY;
                        options.PageWidth = (float)sizeExtX;
                    }
                    jpegOptions.VectorRasterizationOptions = options;

                    image.Save(fs, jpegOptions);
                }
            }
    }

默认后备字体

添加了设置默认后备字体的工具。

MTEXT 中的 DXF 到 PDF 透明度效果

据观察，在“DXF”到“PDF”的转换过程中，“MTEXT”（多文本）正在失去透明度。现在这个问题已经解决了。

以下是一个简单的 C# 代码片段，它通过 API 将特定图层从 DXF 格式转换为 PDF 格式：

string MyDir = RunExamples.GetDataDir_DXFDrawings();
string sourceFilePath = MyDir + "conic_pyramid.dxf";
using (Aspose.CAD.Image image = Aspose.CAD.Image.Load(sourceFilePath))
    {
        //  Create an instance of CadRasterizationOptions and set its various properties
        Aspose.CAD.ImageOptions.CadRasterizationOptions rasterizationOptions = new Aspose.CAD.ImageOptions.CadRasterizationOptions();
        rasterizationOptions.PageWidth = 1600;
        rasterizationOptions.PageHeight = 1600;

        // Add desired layers
        rasterizationOptions.Layers = new string[] { "LayerA" };
        // Create an instance of PdfOptions
        Aspose.CAD.ImageOptions.PdfOptions pdfOptions = new Aspose.CAD.ImageOptions.PdfOptions();
        
        // Set the VectorRasterizationOptions property
        pdfOptions.VectorRasterizationOptions = rasterizationOptions;

        MyDir = MyDir + "conic_pyramid_layer_out.pdf";
        
        //Export the DXF to PDF
        image.Save(MyDir, pdfOptions);                
    }
