使用VisioAutomation.vdx 导出 visio的vdx文件 博客分类： C# .NET接口+对接调试 visiovdxVisioAutomation绘制visio

因为项目需要，开始学习并使用VisioAutomation.vdx,实现代码绘制visio图像。

要求完成一个小的应用程序，提供webservice接口，接收json数据，绘制不同类型的visio图。
因为需要在正式项目中使用涉及visio版权问题，所以服务端是不能安装office visio。寻找了很多资料后决定只能使用VisioAutomation.vdx，绘制vdx文件是比较方便的做法。

架构设计：
封装为 WEB服务，基于REST风格
+ 部署在IIS中
+ 执行POST请求，提交JSON数据源，输出vdx
+ 封装客户端驱动，JAVA语言， JS语言

需要绘制模具，vss文件。
axDrawingControl1.Document.Application.Documents.OpenEx("Basic_U.vss",(short)Visio.VisOpenSaveArgs.visOpenDocked);

代码,初始方法：
  string output_filename = @"F:\\hhpp1.vdx";

            // First load a starter VDX (a.k.a "the template") - we will build a new VDX from this one
            //var template_dom = System.Xml.Linq.XDocument.Load("F:\\model.vdx");
            var template_dom = System.Xml.Linq.XDocument.Parse(VA.VDX.Elements.Drawing.DefaultTemplateXML);

            // Clean up the template - remove the existing pages
            VA.VDX.VDXWriter.CleanUpTemplate(template_dom);

            // Create a new Drawing based on the template
            var doc = new VA.VDX.Elements.Drawing(template_dom);

             GetPage01_Simple_Fill_Format(doc);

            var w1 = new VA.VDX.Elements.DocumentWindow();
            w1.ShowGrid = false;
            w1.ShowGuides = false;
            w1.ShowConnectionPoints = false;
            w1.ShowPageBreaks = false;
            w1.Page = 0;
           
            doc.Windows.Add(w1);

            // now create a writer object
            var vdx_writer = new VA.VDX.VDXWriter();
           
            // merge the template with the new in-memory drawing and save it to the output fie
            vdx_writer.CreateVDX(doc, template_dom, output_filename);

绘图方法：
private VA.VDX.Elements.Page GetPage01_Simple_Fill_Format(VA.VDX.Elements.Drawing doc)
        {
            var page = new VA.VDX.Elements.Page(8, 4);
            doc.Pages.Add(page);
          
            // find the id of the master for rounded rectangles
            int rounded_rect_id = doc.GetMasterMetaData("Rounded REctAngle").ID;

            // using that ID draw a rounded rectangle at pinpos(4,3)
            var shape1 = new VA.VDX.Elements.Shape(rounded_rect_id, 4, 3);
            page.Shapes.Add(shape1);

            // using that ID draw a rounded rectangle at pinpos(2,2) with size (2.5,2)
            var shape2 = new VA.VDX.Elements.Shape(rounded_rect_id, 2, 2, 2.5, 2);
            page.Shapes.Add(shape2);

            // set the fill properties of the second shape
            shape2.Fill = new VA.VDX.Sections.Fill();
            shape2.Fill.ForegroundColor.Result = 0xff0000;
            shape2.Fill.BackgroundColor.Result = 0x55ff00;
            shape2.Fill.ForegroundTransparency.Result = 0.1;
            shape2.Fill.BackgroundTransparency.Result = 0.9;
            shape2.Fill.Pattern.Result = 40;

            shape1.Line = new VA.VDX.Elements.Line();
            shape1.Line.Weight.Result = 1.0;

            shape1.XForm.Angle.Result = System.Math.PI/4;

            return page;
        }
