Aspose.CAD for .NET是一個獨立的AutoCAD處理API。它提供將DWG，DWF和DXF文件轉換為高質量PDF和光柵圖像的功能。開發人員可以從AutoCAD文件中選擇和轉換特定的布局和圖層，并輕松跟蹤整個文件轉換過程。

近期Aspose.CAD for .Net更新至最新版v20.3，新增了三個非常實用的新功能——為DWG和DXF實現自動代碼頁檢測、支持DWFX文件、中斷或在保存上設置超時，接下來，我們通過示例來了解新增功能！

新增與改善

完整更新細則請參考：【Aspose.CAD for .NET v20.3更新說明】

CADNET-810-為DWG和DXF實現自動代碼頁檢測

using (CadImage cadImage = (CadImage)Image.Load(
    GetFileFromDesktop("file.dwg"),
    new LoadOptions()
    {
        SpecifiedEncoding = CodePages.Japanese,
        SpecifiedMifEncoding = MifCodePages.Japanese,
        RecoverMalformedCifMif = false
    }))
{
    //do export or something else with cadImage
}

CADNET-593-支持DWFX文件

using (Image cadDrawing = Image.Load("example-580-W.dwfx"))
{
    var rasterizationOptions = new CadRasterizationOptions();
 
    rasterizationOptions.PageWidth = cadDrawing.Size.Width;
    rasterizationOptions.PageHeight = cadDrawing.Size.Height;
 
    PdfOptions CADf = new PdfOptions();
    CADf.VectorRasterizationOptions = rasterizationOptions;
 
    cadDrawing.Save("example-580-W_custom.pdf", CADf);
}

CADNET-818-如何中斷或在保存上設置超時

 using (Image cadDrawing = Image.Load("huge-drawing.dwg"))
{
    var rasterizationOptions = new CadRasterizationOptions();
 
    rasterizationOptions.PageWidth = cadDrawing.Size.Width;
    rasterizationOptions.PageHeight = cadDrawing.Size.Height;
 
    using (var its = new InterruptionTokenSource())
    {
        PdfOptions CADf = new PdfOptions();
        CADf.VectorRasterizationOptions = rasterizationOptions;
        CADf.InterruptionToken = its.Token;
 
        var exportTask = Task.Factory.StartNew(() =>
        {
            cadDrawing.Save("example-580-W_custom.pdf", CADf);
        });
 
        Thread.Sleep(10000);
        its.Interrupt();
 
        exportTask.Wait();
    }
}
