Hi Manish,


Thanks for contacting support.

Can you please share the source HTML file so that we can test the scenario at our end. We are sorry for this inconvenience.

Hi Manish,

Thanks for sharing additional information. I have tested the scenario with Aspose.Pdf for NET 8.6.0 but I am getting an empty file instead any error. We have logged the issue in our bug tracking system as PDFNEWNET-36106 for further investigation and resolution. We will notify you via this thread as soon as it is resolved.

We are sorry for the inconvenience caused.

Best Regards,

Hi,

Lets assume you are not getting same error in logs which we are getting. Still this is your product. Could you let us know in what consitions this error would popup.

Also, please let me know following for test environment where you have tried replicating this issue:

(1) Operating System

(2) 32bits/64bits

(3) .Net framework

(4) IIS version

Regards,

Manish

Hi Manish,


Thanks for sharing the details.

In our earlier attempt, we have tried replicating the issue over Windows 7 and as per our observations, OutOfMemoryException is being generated when trying to convert HTML file to PDF format. However we will definitely consider the error which you have been facing and will try our level best to investigate the problem with that perspective. The development team will further look into the details of these problems and we will keep you posted on the status of correction. Please be patient and spare us little time.

The issues you have found earlier (filed as PDFNEWNET-36106) have been fixed in Aspose.Pdf for .NET 9.5.0.
