Delphi 10.2 and LeadTools SDK - How to access LeadTools SDK

What is the best way to access LeadTools SDK from Delphi 10.2? Do I have to import the C#DLL or is it better to use the .NET assemblies? I see there is a .NET Runtime Library for Delphi that one can install but not sure if I should do that.

What I want to achieve eventually is an application that polls a folder for new PDF files containing invoices. OCR those files and return the data to a data table. That must include the headers, footers and the detailed lines. Not sure what is involved in that.

Thanks in advance

Hello,

Apologies, but we don't have VCL components for Delphi 10.2 Tokyo. We recommend using our CDLL libraries for new development. If you wish to use capabilities not available in Delphi, it'll be necessary to do so using one of the supported platforms. We have a chart showing which LEADTOOLS technologies are available on specific platforms.

Thanks Nick

I know you don't have VCL components for Delphi. That's why I asked what would be easiest to get going with the SDK. The C#DLL or .NET libraries? You answered CDLL. Now I want to know how to get started in Delphi? Which DLL's must be imported. There are 100's of them in the \LEADTOOLS 20\Bin\CDLL\Win32 folder.

Please see our online documentation on "Files to be Included with your Application" for which libraries you need to reference in your project.

You should be able to use LEADTOOLS with most versions of Delphi via the Win32 and x64 DLLs, which have declarations and definitions in the USES folder. Note we don't have any quick-start guides or tutorials for Delphi but some examples are available in the installation folder.
