Hi,

LiteralClosedDefectsTrend.Text = lGraphXML; // This is graph xml been generated
lFnDownloadGraph(lGraphXML);
void lFnDownloadGraph(string aStrXMLGraph)
        {
            try
            {
                SWFToImage.SWFToImageObject lObjswfobj = new SWFToImage.SWFToImageObject();
                lObjswfobj.InitLibrary("demo", "demo");
                lObjswfobj.InputSWFFileName = Server.MapPath("FusionCharts/") + "FCF_MSColumn3D.swf";
                string lStrNeededEtx = "jpg";
                string lStrSelectedExtn = "";

                if (lStrNeededEtx == "jpg")
                {
                    lObjswfobj.ImageOutputType = TImageOutputType.iotJPG;
                    lStrSelectedExtn = ".jpg";
                }
                else
                {
                    if (lStrNeededEtx == "gif")
                    {
                        lObjswfobj.ImageOutputType = TImageOutputType.iotGIF;
                        lStrSelectedExtn = ".gif";
                    }
                    else
                    {
                        if (lStrNeededEtx == "png")
                        {
                            lObjswfobj.ImageOutputType = TImageOutputType.iotPNG;
                            lStrSelectedExtn = ".png";
                        }
                        else
                        {
                            if (lStrNeededEtx == "bmp")
                            {
                                lObjswfobj.ImageOutputType = TImageOutputType.iotBMP;
                                lStrSelectedExtn = ".bmp";
                            }
                        }
                    }
                }
                string lStrFilenm = "FCF_StackedColumn3D" + lStrSelectedExtn;
                lObjswfobj.Execute_Begin();
                
                lObjswfobj.Execute_SetVariable("dataXML", aStrXMLGraph);
                lObjswfobj.Execute_SetVariable("chartWidth", "750");
                lObjswfobj.Execute_SetVariable("chartHeight", "600");
                lObjswfobj.ImageWidth = 600;
                lObjswfobj.ImageHeight = 500;
                lObjswfobj.Execute_GetImage();
                string lFilePath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
                lObjswfobj.SaveToFile(lFilePath + @"\" + lStrFilenm);
                lObjswfobj.Execute_End();
                //DownloadImage(lStrFilenm);
            }
            catch (Exception)
            {
                throw;
            }
        }

推荐答案

你好。我解决了你的代码。解决方案是在行lObjswfobj.Execute_GetImage（）;之前添加这个简单的行。 ：



Thread.Sleep（4000）;



在C＃中的方式是：



SWFToImageObject swfobj = new SWFToImageObject（）;

swfobj.InitLibrary（demo，demo）;

swfobj .InputSWFFileName = Server.MapPath（〜/ bin / ScrollLine2D.swf）;

swfobj.ImageOutputType = TImageOutputType.iotJPG;

swfobj.Execute_Begin（）;

swfobj.Execute_SetVariable（dataXML，aStrXMLGraph）;

swfobj.Execute_SetVariable（chartWidth，650）;

swfobj.Execute_SetVariable（ chartHeight，450）;

swfobj.ImageWidth = 650;

swfobj.ImageHeight = 450;

Thread.Sleep（4000 ）;

swfobj.Execute_GetImage（）;



如果这种方式不适合你...你应该测试添加更多毫秒。

问候

hello. I resolved your code. The solution is add this simple line before line "lObjswfobj.Execute_GetImage();" :

Thread.Sleep(4000);

In C# the way is:

SWFToImageObject swfobj = new SWFToImageObject();
swfobj.InitLibrary("demo", "demo");
swfobj.InputSWFFileName = Server.MapPath("~/bin/ScrollLine2D.swf");
swfobj.ImageOutputType = TImageOutputType.iotJPG;
swfobj.Execute_Begin();
swfobj.Execute_SetVariable("dataXML", aStrXMLGraph);
swfobj.Execute_SetVariable("chartWidth", "650");
swfobj.Execute_SetVariable("chartHeight", "450");
swfobj.ImageWidth = 650;
swfobj.ImageHeight = 450;
Thread.Sleep(4000);
swfobj.Execute_GetImage();

if this way not working for you... you should test add more milliseconds.
