Wondering about XPM to DNG? Here's exactly what works, what doesn't, and why.
You can't create a genuine DNG from a finished XPM — but DNG conversion from camera RAW is real. Here's the full picture.
DNG is a RAW container built to hold the unprocessed data straight off a camera sensor. A XPM is an already-developed image — wrapping it in a DNG can't recreate the dynamic range or color depth it never kept.
Where DNG shines is converting a camera's own RAW (CR2, NEF, ARW…) into the open DNG format for archiving. That's a true conversion; turning a finished XPM into RAW is not.
DNG standardizes the proprietary RAW that cameras produce — these are the formats it replaces or wraps:
XPM (X PixMap) is the X Window color icon format, stored as editable C source — long used for application icons and cursors on Unix and Linux.
