Add Image to PDF with changed name of image gives error when opening output pdf file

Aspose.PDF Product Family
1

I am working with Aspose .pdf for .Net with c#. When I Use the code copied from the sample code, the output file opens without problem. While adding the image to PDF file, if I change name of image using code
image.Name = “NewName”;
The output file gets created without any problem. When you try to open it under Acrobat reader, it gives error message.

Thanks for the update.

I downloaded the new package from the site given .
A file named “aspose.pdf.20.7.0.nupkg” got downloaded of size approx 1.5GB.

But the file cant be opened. Must be because the “.nupkg” is non standard file extension.

Please throw some light on this.

You can directly install the API using NuGet Package Manager in Visual Studio. In case of manually download, please rename the downloaded package and change its extension as .zip. Then you will be able to extract the DLLs.
