CMYK encoded jpegs are technically within spec ( https://www.itu.int/rec/T-REC-T.872-201206-I/en) but are exceedingly uncommon and support is pretty sporatic. Typically a JPEG contains RGB data encoded as YCbCr. If your application strictly requires CMYK data, you probably want to consider another file format.

I found an online site that works but would like to do it on my machine. Searching has only found how to do it for tiff files. -- Dennis Payne dulsi@identicalsoftware.com https://social.freegamedev.net/channel/dulsi _______________________________________________ WLUG mailing list -- wlug@lists.wlug.org To unsubscribe send an email to wlug-leave@lists.wlug.org Create Account: https://wlug.mailman3.com/accounts/signup/ Change Settings: https://wlug.mailman3.com/postorius/lists/wlug.lists.wlug.org/ Web Forum/Archive: https://wlug.mailman3.com/hyperkitty/list/wlug@lists.wlug.org/message/JH76OH...
