Watermarks

[Lucas Lima]

Hello, I am trying to implement a method on a dotnet core webservice to add a watermark in a PDF.

The example method in documentation returns an error:

error NU1102: Unable to find package Syncfusion.Compression.Portable with version (>= 19.2.0.62)

error NU1102: - Found 1 version(s) in nuget.org [ Nearest version: 15.2120.0.46 ]

Best regards,

Lucas Lima

Hi Lucas,  

Thank you for contacting Syncfusion support.  

  

The reported error might be due to a mismatched product version of Syncfusion assemblies. So, we request you to refer to the same product version of Syncfusion assemblies to resolve this issue. Please refer to the below link,

Note: If you are adding multiple Syncfusion assemblies to your project, it is dependent assemblies must be of the same assembly version, if they are different then this error will occur. For instance, if you use “Syncfusion.Compression.Base.dll” of version(19.2.0.62), then all other Syncfusion assemblies in the project should be of the same version. 

We have attached the sample for adding the watermark text in a PDF document for your reference, please find the sample and output document from below,
