1 File size (MB) =
0.294118 Image size (megapixels)

Explanation

DNG uncompressed assumes 3400000 bytes per megapixel. MP = MB x (1,000,000 / 3400000). With input 1 MB, output is 0.294117647059 MP.

For File size to Image size, the active encoding/quality profile determines the conversion constants applied to every value.

Keep the same profile in both directions to avoid mixing lookup systems that use different size mappings.

Method & Reference (Verified)

  • Method basis: profile-bound mapping; constants depend on the selected profile encoded in the route.
  • Profile reference: encoding/quality profile.
  • Consistency rule: keep the same profile in mirror direction to avoid mixing incompatible mappings.
