DynamicPDF Rasterizer for .NET (v2) Forum

Trying to use the Rasterizer with a AWS Lambda Function and getting this error:

"Unable to load shared library 'DPDFRenderNative_x64' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libDPDFRenderNative_x64: cannot open shared object file: No such file or directory\n   at ceTe.DynamicPDF.Rasterizer.RenderNativeWin64.a(String A_0, String A_1, UInt64& A_2)\n   at ceTe.DynamicPDF.Rasterizer.PdfiumUtilityClass.a(String A_0, String A_1, UInt64& A_2)\n   at ceTe.DynamicPDF.Rasterizer.InputPdf..ctor(String filePath)\n   at ocr_lambda.Function.FunctionHandler(String input, ILambdaContext context)"

Everything works just fine localhost, even on "Mock Lambda Test Tool".

Any guess?

Hello,

Please place the native DLL (DPDFRenderNative_x64.dll or DPDFRenderNative_x86.dll) in the same folder as the .NET DLL (DynamicPDF.Rasterizer.XXXX.dll).

Thanks,

But the problem still exist。
I reference the package via nuget whith named "ceTe.DynamicPDF.Rasterizer.NET".
My project is running on centos7_x64。
All releated dlls are in the same folder

Debug mode on win10 is OK。 AnyCpu mode

Hello,

You are getting error because DynamicPDF Rasterizer does not currently support the Linux platform. We are working on this feature and plan to include it in a future version of the product.

Thanks,
ceTe Software Support Team
Ok. Please update this thread when this feature is available.

Hello,

Support for the Linux platform has been included in the latest version (v3.08) of DynamicPDF Rasterizer. You can download the latest version from NuGet (product ID : ceTe.DynamicPDF.Rasterizer.NET) or from our website here.

Please note, that the libDPDFRenderNative_XXX.so must be added to your project and must be deployed along with the DynamicPDF.Rasterizer.NETStandard20.dll for Linux builds.

Thanks,

Works like a charm! Thank you!

In order to use it with Lambda functions, on a serverless application, what kind of License should be purchased?

Hi,

Great to hear!

A developer license is needed for serverless applications. They are royalty free and are not tied to a server (physical or virtual) in any way.

Hello, I have the same problem. I'm working on a .net core project with mac OS.

Hello,

It looks like the libDPDFRenderNative_x64 file is not deployed along with the DynamicPDF.Rasterizer.NETStandard20.dll file. This could be the reason for getting error. Please try placing the respective native DLL file along with the DynamicPDF.Rasterizer.NETStandard20.dll file and see that works. You can refer to the documentation on referencing the assembly and deployment here.

Thanks,
