Aspose.Word under mono

mgdis01 · April 13, 2011, 9:57am

Hi Aspose Team,
I’m trying to resolve 2 issues with aspose.words under mono/apache. Do you have any information on this that could help me ? Thanks
1- CultureInfo, mono, mod_mono, apache and date language
template : { MERGEFIELD date @ “d MMMM yyyy”}
data : 1 column (type string), 1 row (“2011/01/01”)
When I merge my template with this data in an executable under mono, it works fine, the mergefield is replaced by “1 janvier 2011”.
Thread.CurrentThread.CurrentCulture.Name returns “fr-FR”.
The same code with an ASPNET application (mono + apache) replace the mergefield whith the date in english.
Thread.CurrentThread.CurrentCulture.Name returns string.empty.
2- pdf conversion under mono
When I try to save any .doc file as .pdf file, I’m getting this exception :
ex.Message :

Hi
Thanks for your request.

I think you can just set current culture to get the expected result. For instance see the following code:

CultureInfo currentCulture = Thread.CurrentThread.CurrentCulture;
// Set German culture for testing. 
Thread.CurrentThread.CurrentCulture = new CultureInfo("de-DE");
Document doc = new Document(@"Test001\in.doc");
doc.MailMerge.Execute(new string[] { "fieldName1" }, new object[] { 0 });
doc.Save(@"Test001\out.doc");
Thread.CurrentThread.CurrentCulture = currentCulture;

I think, the problem might occur because Aspose.Word cannot find fonts. Currently, Aspose.Words expects to find fonts in /usr/share/fonts/ttf. So please make sure that this folder contains TrueType fonts.
https://docs.aspose.com/words/net/system-requirements/
Hope this helps.
Best regards.

Hi
1- thank you for this workaround, but I’m trying to understand why I lost cultureinfo when i run an ASPNET application
2- Doc to pdf conversion works fine with an executable, but don’t work with my ASPNET application.
It seems that the environment variable DISPLAY isn’t correct in this case (System.ArgumentNullException: Could not open display (X-Server required. Check you DISPLAY environment variable))
When you did some tests on mono, did you try with an ASPNET application or you launched an executable ? Maybe I forget something on mod_mono or apache configuration, but it’s hard to find any information on this, and if you get these issues while testing, any infomation would be usefull for me .
Thanks for your help

alexey.noskov · April 15, 2011, 1:20am

Hi
Thanks for your request.

This might occur if you did not specify default culture for your ASP.NET application. In this case if a specific culture is not specified (or empty string used instead of culture name), InvariantCulture is used.
You can try specifying default culture of your ASP.NET application in web.config in globalization section:
https://learn.microsoft.com/en-US/troubleshoot/developer/webapps/aspnet/development/set-current-culture
I will configure environment with mono and apache and let you know how it goes on my side.
Best regards,

alexey.noskov · April 15, 2011, 10:21am

Hi
Just tested PDF generation in ASP.NET application run under mono in apache. Here is simple code I used for testing:

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.Writeln("Hello World!!!");
doc.Save(Response, "out.pdf", ContentDisposition.Attachment, new PdfSaveOptions());

I can successfully generate and open the generated PDF document on my side.
Best regards,

Hi
I’m testing again with latest version of Aspose.Words (9.7.00)
I’m getting this exception: Cannot find black listed licenses resource. Please report this error to Aspose.
I tried to attach my license file but license files are not allowed here. Should I send it by email ?
Any idea ?
Thanks

alexey.noskov · April 18, 2011, 5:28am

Hi
Thanks for your request. Which of Aspose.Words dlls do you use? There are dlls for .NET 1.1, 2.0 and 3.5. I used .NET 2.0 dll for testing. Which version of mono do you use? On my side I used mono 2.6.7.
The problem also can occur if you disassembled the Aspose.Words.dll and tried to change it.
Best regards,

mgdis01 · April 18, 2011, 5:42am

I used Net 2.0 dlls. I’m testing with mono 2.4.3.1.
I’ll try with mono 2.6.7
Thanks

alexey.noskov · April 18, 2011, 6:51am

Hi
Please let me know how it goes with Mono 2.6.7.
In addition, I would suggest you use the latest version of Aspose.Words (9.8.0). In the latest version of Aspose.Words we added an ability to specify folder(s) where Aspose.Words should look for fonts. This ability is very important if you use Aspose.Words under mono in Linux.
For instance, you can use the following code to specify fonts directory:

// Aspose.Words will look for fonts in the specified directory and all subdirectories.
FontSettings.SetFontsFolder("/usr/share/fonts", true);
Document doc = new Document("/home/alexey/Projects/in.doc");
doc.Save("/home/alexey/Projects/out.pdf");

You can download the latest version from here:
https://releases.aspose.com/words/net
Best regards,

mgdis01 · April 18, 2011, 7:44am

Thank you for your quick replies.
I’ve updated mono and aspose dlls :
mono 2.6.7 (+mod_mono/apache)
Aspose.Words.dll 9.8.0
Aspose.Cells.dll 5.3.2
Aspose.Slides.dll 5.1.0
Aspose.pdf.dll 5.1.0
The same .lic file is used for each test.
Test #1 : .doc creation with Aspose.Words

Hi
Thank you for additional information. Could you please provide me a code and test documents you are using for testing Aspose.Words? I will check them on my side and provide you more information.
Best regards,

mgdis01 · April 18, 2011, 7:54am

additional information :
Same tests (same dlls, licence file, aspnet application, template and data) on IIS serveur : tests are ok

mgdis01 · April 18, 2011, 8:23am

It is hard to provide a short code.
- load .doc templat
- MailMerge.Execute(my data)
- some documentvisitor and other process
- => Save as IN.doc => I attached this file
- call document.UpdateFields()
=> error
So I suppose you could reproduce my error with loading IN.doc and calling document.UpdateFields() direcly ?
(For test #3, I have to post on Aspose.Slides forum too, or someone from the Slides Aspose team will come here ?)

alexey.noskov · April 18, 2011, 9:46am

Hi
Thank you for additioanl information. Unfortunately, I still cannot reproduce the problem on my side. I used the following code for testing:

using System;
using System.Web;
using System.Web.UI;
using Aspose.Words;
using Aspose.Words.Saving;
using Aspose.Words.Fonts;
namespace testaspnet
{
    public partial class Default : System.Web.UI.Page
    {
        public virtual void button1Clicked(object sender, EventArgs args)
        {
            License lic = new License();
            lic.SetLicense(Server.MapPath("Aspose.Words.lic"));
            // Aspose.Words will look for fonts in the specified directory and all subdirectories.
            FontSettings.SetFontsFolder("/usr/share/fonts", true);
            Document doc = new Document(Server.MapPath("in.doc"));
            doc.UpdateFields();
            doc.Save(Response, "out.pdf", ContentDisposition.Attachment, new PdfSaveOptions());
        }
    }
}

Regarding Aspose.Slides, it would be better if you ask your question in Aspose.Slides forum.
Best regards,

mgdis01 · April 19, 2011, 2:01am

Hi Alexey
“CodePage 1251 not supported” issue has been resolved by installing “mono-locale-extras” package, wich contains I18.Other dll.
There are still one issue on ppt creation (I’ll post on Aspose.Slides forum) and on doc to pdf conversion (I’ll make other tests, and try to give you enough information to reproduce on your side).
Thanks for your help

mgdis01 · April 19, 2011, 3:09am

“Cannot find black listed licenses resource” issue occurs on Aspose.pdf license loading. I’ll post on Aspose.pdf forum for this.

alexey.noskov · April 19, 2011, 3:31am

Hi
It is perfect that you managed to resolve the problem with Aspose.Words. Please feel free to ask in case of any issues, we will be glad to help you.
Hope my colleagues from Aspose.Slides and Aspose.Pdf team will be able to help you to resolve the problems.
Best regards,

mgdis01 · April 19, 2011, 3:42am

Alexey,
I did some tests on doc to pdf conversion using Aspose.Words on mono server, it seems that it works fine now.
Thanks

adam.skelton · April 19, 2011, 10:01pm

Hi there,
It’s great that it’s working as expected now. If you have any further queries, please feel free to ask.
Thanks,
