Description
|
The number of bits per sample is not correctly transcoded between standard and native image metadata. The bits field representation for a number of bits N in JPEG 2000 is
B = (isSigned ? 0x80 : 0x00) | ((N - 1)&0x7f)

Evaluation
|
Native -> Standard
Wrong mask being used to derive bit count from JPEG 2000 field: 0x80 instead of 0x7f.
Standard-> Native
Values used straightaway without proper conversion.
