libheif not found WSA/Android ImageSharp

[prabhav-mehra]

Thanks for this library, very helpful for what I am working on.

I am trying to load an HEIC image using ImageSharp using this library. It works on windows but when I try to load it on android (I am using WSA, haven't gotten a chance to test on actual device but I would imagine it being the same), I get libheif not found.

I have installed both 'LibHeif.Native.win-x64' and 'LibHeif.Native.linux-x64'. for some reason 'LibHeif.Native' give me errors so I had install both separately.

System.DllNotFoundException: 'libheif'

I know heic is an ios specific image type but I wanted to cover all user scenarios (i.e. if a user has saved an heic image in file system and wants to load that)

For runtimes other than linux x64/windows x64 you will need to get build of libheif for ARM runtime.
I think this is only way to get work libheif-sharp on android devices.

Are there any steps on how to incorporate the ARM build for this to work? Also little confused about the get work libheif-sharp on android devices, does this mean this library can't work android?

@hey-red when I get access to .so files 0xC0000054/libheif-sharp#9 (comment) required for android. do I have to add similar code as linux/win build src files

@hey-red I get “dll not found” on an iOS device as well. Is that expected? I would think it would be supported on iOS as that it the most common os which supports heif images

[prabhav-mehra]

@hey-red would it be possible if you could add support for android and ios in the library itself? I tried few things but I never got this working.

Since you have already the system/steps sorted with the builds for linux and windows, it would be very helpful to get it working on android and ios as well.

libheif-sharp supports android and ios but needs to be built with android and ios dlls for it to work.
