如何将autocad文件转换为清晰的pdf文件？

Question

我正在做一个将autocad文件.dwg转换成PDF的asp.net项目。

我使用以下代码来完成此操作：

using (var image = Aspose.CAD.Image.Load(filePath))
{
    // create an instance of CadRasterizationOptions & set resultant page size

    var rasterizationOptions = new Aspose.CAD.ImageOptions.CadRasterizationOptions()
    {
        PageSize = new Aspose.CAD.SizeF(image.Size.Width, image.Size.Height),
    };

    // save resultant PDF
    image.Save("****" + "***", new Aspose.CAD.ImageOptions.PdfOptions() { VectorRasterizationOptions = rasterizationOptions });
}

我得到的pdf如下：

我想要的建筑是在pdf文件的中心和足够大，以便于用户使用。我怎样才能修正这个视图并使其清晰呢？

Answer 1

我已经观察到了您分享的示例代码。你能分享一下你在导出PDF中遇到的问题吗？您可以分享源DWG文件与预期的输出PDF。此外，在上图中，当您在应用程序中设置Aspose.CAD的许可证时，左上角的水印将被移除。

我在Aspose担任支持开发人员/布道者。

非常感谢

我建议你尝试使用下面的示例代码来设置渲染文件的打印区域。

        var cadImage =(CadImage) Aspose.CAD.Image.Load("filePath");

        CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
        rasterizationOptions.Layouts = new string[] { "Model" };
        rasterizationOptions.NoScaling = true;

        // note: preserving some empty borders around part of image is the responsibility of customer
        // top left point of region to draw
        Point topLeft = new Point(6156, 7053);
        double width = 3108;
        double height = 2489;

        CadVportTableObject newView = new CadVportTableObject();
        newView.Name = new CadStringParameter();
        newView.Name.Init("*Active");
        newView.CenterPoint.X = topLeft.X + width / 2f;
        newView.CenterPoint.Y = topLeft.Y - height / 2f;
        newView.ViewHeight.Value = height;
        newView.ViewAspectRatio.Value = width / height;

        for (int i = 0; i < cadImage.ViewPorts.Count; i++)
        {
            CadVportTableObject currentView = (CadVportTableObject)(cadImage.ViewPorts[i]);
            if (cadImage.ViewPorts.Count == 1 || string.Equals(currentView.Name.Value.ToLowerInvariant(), "*active"))
            {
                cadImage.ViewPorts[i] = newView;
                break;
            }
        }


        cadImage.Save("Saved.pdf", new Aspose.CAD.ImageOptions.PdfOptions() { VectorRasterizationOptions = rasterizationOptions });
