Image Collection in HEIC Container / C# Interface ?

Question

As an example, I have This HEIC Sample File. It contains an Image collection in one single container.

 

I have been looking for a NET library that allows me to read Metadata, see how many images are in the container, and extract a specific image on request using a C# interface.

 

As a step, I have been looking into using SWIG with [libheif](https://github.com/strukturag/libheif) to create a DLL library with a C# interface.

 

I created a file in the Project directory named "libheif_Swig.i" containing this :

 

%module libheif

%{

#include "libheif/heif.h"

%}

%include

%include "libheif/heif.h"

 

Changed the properties of this file

 

Custom Build tools/ Command Line: c:\swigwin-4.0.0\swig -csharp -c++ -outdir C:\dump\swig\Generated libheif_Swig.i

Then just right-click libheif_Swig.i and select ‘Compile’. This will generate those files in the Generated folder.

cpp.cs

cpp_file.cs

cppPINVOKE.cs

and this file in the libheif folder

cpp_file_wrap.cxx

 

It is a very simple process that shouldnt take more than 5 min. My old PC however cant seem to handle it for some reason.

 

can someone hep compiling the SWIG interface, Create a DLL library with a C# interface or even point to a direction where there is a sulotion already made?

 

I am very thankful to all of you !
