Sorry ... I don't either
. Just kidding!
I meant that you'd need to create something like this in VB.Net/C# - there are ways to then have it interoperate with lisp.
I've done some more googling, it seems there is an OpenSource one:
SImage. Basically it's a DLL which you'll need to register using a windows command-line (CMD console):
regsrv32 SImageUtil.dll
Thereafter you can use
(vlax-get-or-create-object "SImageUtil.Image")
To obtain a link to this utility. Then the normal vlax-get/put/invoke methods should work.
I haven't tested it myself, but from the
documentation it does have a GetExif & DumpExif method.
