Title: manipulate exif data only, without an image
Post by: dk on February 18, 2024, 07:31:03 AM
Hello,

How would I use ExifTool perl API to manipulate the jfif data I read from jpeg by other tools?
The data I use later with libjpeg.j_write_extras ( those that start with Exif\x0\x0 ) but I couldn't find how to use ExifTool to operate and create these raw strings - not jpeg file itself

Thank you!

This isn't really part of the public interface.  I think it would be easiest to package this as an EXV file and pass this to WriteInfo().
