PDF Export not supporting RTL or Arabic

[patterngen]

Dear Sir,

I have examined  ej2-Grid PDF export.

For English data, it works perfectly.

With the Grid "enableRT:true", the produced PDF document is 

still showing the columns in LTR (and not RTL) fashion.

However , there is a more serious problem which is:

    When some of the cells data is Arabic, the PDF document is

     not produced at all;  the error (in Dev Console):

Uncaught (in promise) Error: ArgumentOutOfRangeException:index, The character is not supported by the font.

Hi Patterngen, 

Thanks for contacting Syncfusion support. 

Query1: When some of the cells data is Arabic, the PDF document is not produced at all 

We have analyzed your requirement and we have already considered “Support for true type font in PDF library” as a feature request and logged a report for the same. This feature will be available in our Essential Studio Volume 2, 2018 release.

We have considered “Support for drawing RTL text in PDF” as a feature request and logged a report for the same. This feature will be available in any of our upcoming releases.

Thanks much  Mr.  R.Dhivya. 

Wow!  Good news for developers in the middle east.

I am also testing ASP.Net Report Viewer API  in a cross-origin setting

and having some problems ... more info. later.

Hi Patterngen, 

We have tested the reported issue by specifying the EnableCors (cross-origin) for the ReportViewer WebAPI controller as shown in shared code example and its working properly at our end. So, can you please share the error detail or issue reproducible screenshot to validate the mentioned problem at our end.  

 

WebAPI: 

    [EnableCors(origins: "*", headers: "*", methods: "*")] 

    public class AssetSummaryController : ApiController, IReportController 

    { 

        [System.Web.Http.ActionName("GetResource")] 

        [AcceptVerbs("GET")] 

        public object GetResource(string key, string resourceType, bool isPrinting) 

        { 

            //Returns the report resource for the requested key. 

            return ReportHelper.GetResource(key, resourceType, isPrinting); 

        } 

 

        public void OnInitReportOptions(ReportViewerOptions reportOptions) 

        { 

            reportOptions.ReportModel.ReportServerCredential = new System.Net.NetworkCredential("ssrs", "RDLReport1"); 

            reportOptions.ReportModel.DataSourceCredentials.Add(new DataSourceCredentials("AdventureWorks", "ssrs1", "RDLReport1")); 

        } 

 

        public void OnReportLoaded(ReportViewerOptions reportOptions) 

        { 

             

        } 

 

        [HttpPost] 

        public object PostReportAction(Dictionary<string, object> jsonData) 

        { 

            //Processes the report request and returns the result. 

            return ReportHelper.ProcessReport(jsonData, this); 

        } 

 

        public string GetText() 

        { 

            return "WebAPI working"; 

        } 

    } 

 

Please refer to the below forum documentation for more information, 

http://enable-cors.org/server_aspnet.html

Yes it is working using the info. you outlined and adding a reference to  AspNet.WebApi.Cors.

Thank you much for speedy reply.

Dears,

Still facing issues with Arabic content in pdf export, I used a true type font `Arial` by converting it to base64 format then I gave it to the pdfExportProperties and it worked on Arabic content in the grid, but when I add a header for the PDF it fails when the header text contain Arabic text, the following error occurs in the console:

Error: ArgumentOutOfRangeException:index, The character is not supported by the font.

And if I add the font to the style of the Text content in the header explicitly the following error occurs:

```

TypeError: Cannot read property 'textDirection' of undefined

Dears,

The issue is with the order of the columns in the exported PDF.. it's shown on the UI as RTL so the exported should be the same.

I checked your sample and the issue of Right-to-Left is still existing, the first column from the right in the grid is shown as the first column from the left in the PDF.

Regards.

[Pavithra Subramaniyam]

Hi mahmod, 

 

Thanks for your update.  

 

We have checked the feasible ways to achieve PDF export in RTL direction but there is no  support for ordering the column based on the RTL in our PDF library.

Pavithra S.

Dears,

Is RTL support issue resolved in pdf ?

[Thiyagu Subramani]

Hi mahmod,  

Thanks for your update. 

No, we currently do not provide support for PDF export to RTL because it is out of scope in our PDF library. 

Please get back to us, if you need any further assistance. 

  

Regards,  

Thiyagu S
