I know that some RAW formats store a small resolution JPEG image for quick preview that is different from a thumbnail. I manage to extract that using third party software such as ExifTool, how is it possible to extract that using LibRaw? Also in the changelog I see that you have added an option for GPS data extraction, but when I try that i.e.
open the file and read the data from imgdata.other.gpsdata it always returns nothing. Is there anything else I should do for after open_file(fileName) to load the needed information?
And the same question for xmpData.
Thank you in advance,
