Very interesting find, Mixer! I was just wondering if the following update might be the solution, …
MSKB ([url=https://support.microsoft.com/kb/2836502]Certain JPEG images cannot be displayed after you install update 2670838 on a Windows 7 SP1 or Windows Server 2008 R2 SP1-based computer[/url]) wrote:Assume that you install update 2670838 on a computer that is running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1. When you use an application to open a JPEG image, the application cannot decode the JPEG image. Therefore, the JPEG image is not displayed.

This issue occurs when the JPEG image is a non-progressive compressed JPEG image whose components span multiple scans.
… but XnView is using IJG's library for compressing and decoding JPEGs.

  Based on the analysis of compression characteristics and EXIF metadata:

  ASSESSMENT: Class 4 - Uncertain if processed or original
              While the EXIF fields indicate original, no compression signatures 
              in the current database were found matching this make/model

  Appears to be new signature for known camera.

Re: Effect Corrupts Jpeg File

Post by Brother Gabriel-Marie »

If it is then I don't know how I could find out.

Problem is that it doesn't happen with *every* jpeg. Only some of them.
The ones in our example were sent me via email from a person using Outlook. Those images were attached to the email, not embedded, and they were never zipped.
I can corrupt any of the photos that were sent to me in that batch.
It doesn't seem to be an issue with that directory, either, because other photos in the same directory and even same XnView instance that not from that batch do not corrupt.

Funny thing is that I can view the "corrupted" file just fine in other viewers.
Using Imagine again, I can see that the xif properties are all still in place.

The only thing I can think of is a cache problem of some sort.

In details mode the image still displays only the hex values in the preview panel.
I removed the cache for that directory but it didn't help.
I disabled caching in Options > Browser > Thumnails > Cache and navigated out and back to that directory, but it didn't help.

Ah! I found something, though!
I have been using a hex editor called XVI32
XVI32 will not open that file either! But it will open the original just fine.

Now, using Universal Viewer as a Hex Editor, however, I CAN open both files.
AND I see something interesting...

The original file's first line of hex is:
FF D8 FF E1 9A 92 45 78 69 66
ÿØÿáš’Exif

But the corrupt file's first line of hex is:
FF D8 FF E0 00 10 4A 46 49 46
ÿØÿà JFIF

What's that JFIF doing there?

I am guessing that XnView wrote some signature incorrectly.

Sounds like a bullshit, hex editors are indifferent towards file content because they display it byte-by-byte. What xvi32 can't open, is file containing characters from foreign codepage in its name.

That's what I'm assuming, but I don't know for sure.
In Br. Gabriel-Marie's configuration, XnView's browser is extracting the embedded EXIF thumbnail.

There are reports that files sent with Outlook get corrupted, but the sample you've provided seems perfectly fine.

I think you're on to something here. DSCN1971 Copy.JPG is missing the APP0 marker.

This is because both specify that their particular application segment (APP0 for JFIF, APP1 for Exif) must be the first in the image file. In practice, many programs and digital cameras produce files with both application segments included. This will not affect the image decoding for most decoders, but poorly designed JFIF or Exif parsers may not recognise the file properly.

Code: Select all

FF D8 FF E0 ...
In this example, immediately following the SOI marker is the APP1 (FF E1) marker that describes Exif information (i.e. shutter speed, aperture, and camera model). The APP0 marker is nowhere to be found! Applications and services such as Apple's ColorSync and iView MultiMedia Pro depend on JPEG files conforming to the JFIF specification for certain functions, such as embedding ICC Color Profiles.

Several new cameras are producing images missing the APP0 marker, and they all read OK in XnView. However, it does appear that XnView's file parser is not very robust when it comes to ignoring errors. While it does do a good job of reading Exif despite error, apparently it will skip the embedded thumb. So, I think it needs to be able to continue reading and not ignore good data, even if some is not. Obviously, this should only be possible if the file does not contain fatal errors.

Anyway, XnTriq had it right about my image, noting that it had a nonfatal error: Illegal number format 32 for tag 010f. The camera indeed must have a firmware bug that writes the number format as 32 instead of 2 (looks transposed in hex - 0x20 instead of 0x02). Therefore, it causes the Make tag (0x010f) to not be read. If this byte is corrected in a hex editor, then all is well again, and the embedded thumbnail shows. Still, it is hard to believe that this one seemingly unimportant byte in the whole file could halt XnView from scanning for the embedded thumb! :shock: :?

A JPEG file may very well contain no resolution information at all and still be compliant with the JPEG standard.
As already said, a second place where resolutions can be found is the optional APP1/EXIF segment. Strictly speaking, JFIF and EXIF are supposed to be mutually exclusive, because both standards wants their segment to be the first one. But in practice, you often find both segments, one of them necessarily in the "wrong" place.
Thirdly, the optional APP13/Photoshop IRB (Image Resource Block) segment has provision for storing resolutions.

Of course, life becomes interesting when two or more of those sources are present and disagree...

Or when a rational values found in IRB (or EXIF) segment has a null denominator... Or a null numerator...

Or when some software try to out-smart the standards : Photoshop used to (still does ?) authoritatively declares 72 dpi for JPEG devoid of any resolution information. Ditto when it deemed the resolution to be too low (<10 dpi IIRC). It also forces the X and Y resolutions to be the same...

[quote="Microsoft Knowledge Base (PRB: "Invalid File Format" from ImgEdit Reading Sony Mavica JPG)"]The Sony Mavica camera generates .JPG files without the required "JFIF" string in the header. The JPEG standard states that an APP0 marker and "JFIF" string (together with the leading SOI marker), make up the header that identifies them as "standard" JPEG/JFIF files. Some applications just recognize the leading "FFD8" SOI marker and don't look for the "JFIF" stamp, thus allowing them to open a wider variety of JPEG files.

I'll keep digging for clues. In the meantime, could you please change the following settings in XnView…
  1. Activate Ignore read errors (Tools » Options... » Read/Write » General)
  2. Deactivate Use Embedded thumbnail (Tools » Options... » Thumbnails » Appearance)
… and report back if this makes a difference?

Wow, you've done a lot of research! That's impressive!

I actually was already trying Ignore Read Errors.

I set both options to no avail.

Also, I have worked with other photos sent via Outlook and had no problems.

No, the full filename and path are quite plain. I was surprised that xvi32 couldn't open the file, too. I'm still surprised. Maybe it's something other than just JFIF/APPO bits that are out of whack. I don't know how to tell anything further.

OK, it seems as though XnView is confused by the fact that the original JPEG (Nikon Coolpix L10) has actually two JPEGs embedded in it: An EXIF thumbnail (160×120) and an additional preview (320×240) :shock:
This has been independently confirmed by JPEGsnoop as well as Jeffrey Friedl's Exif Viewer.

We've seen this before with Sony's DSC-W730 and models from other manufacturers:

This image is 1200×1600 pixels (approximately 2 MP). It is quite heavily compressed, usually to 300..400 kB, which gives a compression ratio of 1:15..1:20.

That "preview image" is 1600×1200 pixels. This means that when you view it on the monitor (320×240 pixels) in a 5× magnification, it shows already all information available. Higher magnifications add just enlargement, without any more detail. They also amplify all compression losses and artifacts, and the "preview image" is quite heavily compressed.

Can you reproduce the bug with (any of) the following photos, Br. Gabriel-Marie?

Re: Effect Corrupts Jpeg File

Okay, I tried it a couple of times.
But I was able to work with all three files.
So I tried all over again and now I am corrupting them.

But I found a rhythmn to it.

When the file corrupts it seems to have something to do with this:
I am opening the file for viewing by double-clicking the jpeg's file icon in Windows Explorer. I can corrupt all three files this way.
But if I already have XnView open and I open the files from XnView's file browser then they do not corrupt. Although I was corrupting the other jpegs (the ones I sent) this way.
But with just these files, they only corrupt if I open them into XnView from Explorer.

However, this round, when I work the effect and then autosave them, I see the hex in the preview panel but the files don't actually corrupt. If I move off the file and back on then the hex is gone.

What's happening with these photos is no the same as what happened to my other ones.
If you all want to test yourselves with my setup, we can work up a TeamViewer session, if you like.

Thanks!

Here's another observation which might help Pierre find out what's going on: With your configuration, the overlay icon isn't displayed although Use Embedded thumbnail is activated. It seems as if XnView has either trouble finding the embedded thumbnail or it can't decide which one (Composite:ThumbnailImage vs. Composite:PreviewImage) to use.
