Modify jpg DPI info without recompress?
I have JPG images produced by a camera that malfunctioned and wrote bad
DPI info (eg. horizontal vertical), and I would like to be able to change the DPI info in the JPGs without recompressing. I would write a program to do it, but I don't know how to locate the DPI info in the JPG files. Can anyone point me to a free program that does this, or to a format description of JPG files so that I can write one myself? If I do write one, I'll be happy to make it available for free download, if anyone is interested.
