Aspose.Words.Viewer.DocumentRenderer causes OutOfMemory-Exception

Aspose.Words Product Family
#1

Hi!

I know your Aspose.Words.Viewer.DocumentRenderer is still in beta state and is not supported by you, but I can do no better now to quickly preview Aspose.Word-generated documents while browsing through several tenthousands docs in my application.

Unfortunately there are some documents containing images (inserted by "InsertImage") which causes the DocumentRenderer immediately to eat up all RAM it could get from the PC, make the machine nearly stopp accepting any input via keyboard or mouse. If I pack the renderer call into a separat thread and abort this thread if it takes to long to finish, it seems that I end up with a huge memory leak (several hundred of megabytes).

Have you got any idea how to prevent this fatal behaviour?

Is it OutOfMemory exception or System.ArgumentException : Parameter is not valid? The #4042 defect seems to mention the ArgumentException only. I will look at this issue in the next few days.

Well, your colleague alexey noskov reproduced the error, he said.

We do not get a message at all because our machines almost immediately stop responding because of heavily swapping and struggling with just a few MB RAM left for operation.

This feature has been in beta for a long time. I’m having a variety of issues with it, including this one. Is there any intent on improving the feature? It is a very desirable feature, and we are at a point where we will have to discontinue use of this Aspose feature from our product due to the severity of some of the issues, unless we hear that it will get some attention in the near future.

Thank you for your interest in Aspose.Worsd features. Unfortunately this feature is still in beta and I can’t provide you any estimate when this feature will be fully supported. Please see FAQ for more information.

Hi

<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

We are happy to tell you that the new Rendering Engine has replaced the “old Viewer Beta”. The Rendering Engine can print, save as images or draw onto .NET Graphics object any document page.

The Problem you have experienced with “old Viewer” does not occur with new Rendering Engine. You can download the latest version of Aspose.Words from here:

http://www.aspose.com/community/files/51/file-format-components/aspose.words/entry158153.aspx

Also new Rendering engine allows you to convert Word document to PDF directly (without using Aspose.Pdf).

Please see Aspose.Words documentation to learn more about new features.

SaveToImage method renders document pages into images:

SaveToPdf method converts the whole document or selected pages to PDF.

Best regards.
