Save a PDF under linux (Ubuntu)

Aspose.Cells Product Family

Hi Guys,

I discovered a bug under Linux (Ubuntu).
I attached a code example on this topic.
DotNetCore_Linux_Sample.zip (555.7 KB)
If the code runs under Windows everything is fine.
If it runs under Linux the following problem occurs:
If I want to save a workbook in the format “xlsx”, “tiff”, “pdf”, “svg” or “html”, i get the error “The type initializer for XXX threw an exception.”.

Since Aspose DotNet Core rules, these formats should also run under Linux.
I use Version 18.8.0
Can you take a look at this hard problem?

Thanks for your support.

@moosbart,

Thanks for your query.

You may please try the new version Aspose.Cells for .NET Core 18.8.1 and also please add reference to System.Drawing.Common and System.Text.Encoding.CodePages into your project. Share the feedback after testing with these updates.

Hi,

Thanks for the note, but unfortunately it does not work.
The result is the same even if I add the both references and the current Aspose reference to 18.8.1
See the screenshots.

@moosbart,

We were able to observe the issue but we need to look into it more. We have logged the issue in our database for investigation and for a fix. Once, we will have some news for you, we will update you in this topic.

@moosbart,

For resolving this problem, check if you have installed “libgdiplus” on linux:
apt-get install libgdiplus
cd /usr/lib
ln -s libgdiplus.so gdiplus.dll

Also you may copy the font files you needed to linux system. You can call “FontConfigs.SetFontFolder” to set the font folder, or just put it to “/usr/share/fonts” folder.

Please give it a try and share the feedback.

Hi,

thanks for the note, but unfortunately, even after the installation of the packet “libgdiplus” i have the same result. I have the package installed and linked successfully.

Much worse, if I update the version 18.8.1 to 18.9.0 i have the following error message. :frowning:

@moosbart,

.NetCore program needs to do some additional initialization, for example:
System.Text.Encoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance);
We have included “CellsHelper.InitForDotNetCore()” method in latest version, and we suggest you to call it first for all .NetCore initialization.

Hi,

Thanks for the notes. I found a solution.
The solution is:

apt-get install libgdiplus
apt-get install libc6-dev
cd / usr / lib
ln -s libgdiplus.so gdiplus.dll

Now it would be nice if the format “Tiff” would work.
Do you have any idea why that could be?
Here is a screenshot of the error message.
