I'm using the IFilter interface to read the content of files such as .docx, .pdf, etc. For those two types (and others) this already works pretty well, but I was wondering if it is possible to use this mechanism to read the meta data of a jpg file as well.
I created a test image file and added some information to its details (Title, description, ...)
Interestingly, the Windows Indexer is able to find this file using the text that I specified as title. By using the IFilter interface, however, I retrieve only an empty string for my jpeg.
I also tested the command line tool filtdump.exe from here: https://msdn.microsoft.com/en-us/library/windows/desktop/dd940434(v=vs.85).aspx#command_line, which returned the same results as my implementation.
Does anyone know how the Windows indexer is able to see the content and how I couold use the same mechanism to achieve similar results?
