XnView: MP 0.85 - 64 bit
OS: Windows 7 64bit
Sometimes Xnview reports different dpi for images than other software (Photoshop,Gimp). Bug?
To reproduce:
check the attached images.
They should both have 250 dpi, but Xnviewmp says 72-250.
Which one is wrong?

XnView MP 0.86 shows both uploaded files as 250 DPI [XnView Classic is unable to read the DPI value for kilartdev- witch DA.jpg...]
Re: 0.85: wrong dpi?
One of the files has conflicting DPI info and is missing the (mandatory) JFIF APP0 marker segment:
- kilartdev- witch AS.jpg
- APP0 (JFIF) → Xdensity & Ydensity: 250
- APP1 (EXIF) → IFD0 → XResolution & YResolution: 250/1 (250)
- APP1 (EXIF) → IFD1 → XResolution & YResolution: 250/1 (250)
- APP13 (Photoshop) → ResolutionInfo (hRes & vRes): 250
- kilartdev- witch DA.jpg
- APP0 (JFIF) → Xdensity & Ydensity: n/a
- APP1 (EXIF) → IFD0 → XResolution & YResolution: 2500000/10000 (250)
- APP1 (EXIF) → IFD1 → XResolution & YResolution: 72/1 (72)
- APP13 (Photoshop) → ResolutionInfo (hRes & vRes): 250
- Image → DPI: {DPI} = 250 / 72 *
- EXIF - Camera → X-Resolution: {EXIF:X-Res} = 250
- EXIF - Camera → Y-Resolution: {EXIF:Y-Res} = 250
