Vista JPG display issue? | The Coffeehouse

Hey I was looking through my DeviantArt collection and I observed this strange thing. Two JPG files I have ('Avarice' and 'Envy' by Blackeri) shows up with a width horribly smaller than its actual width in Windows Photo Gallery and in the thumbnail view.

Internet Explorer, Irfan View and the .NET 2.0 method Bitmap.FromFile(..) show it properly... it shows up nearly as a line (barely 10-12 pixels thick) in the thumbnail view and in Windows Photo Gallery..

I am uploading 'Envy' to here (ImageShack link). Can you 'save target as' and see it whether it shows up distorted on your Vista machines too?

Thanks.

EDIT:
I forgot to mention that it works perfectly on XP.
And here is a link to Blackeri's DeviantART profile.

Something is definately wrong with envyee9.jpg. The thumbnail preview in the explorer window is about 2 px wide and when I open it with the photo viewer it's certainly not the original file. Even when you view it in it's original size it just shows green vertical stripes.

If you open and save it in Paint the image is back to normal.

Weird.

Nice image though. Smiley

Same here on Windows Vista RTM...

How do we decide whether this is a bug in Vista or a problem with the file itself?

The file DOES open in paint, IrfanView, Internet Explorer, .NET 2.0 and a bunch of other programs without issues.

yeah, nice picture. I got the same results. In Explorer and photo gallery it shows up as a green vertical line. In the photo gallery, if I zoom it in, its like its smushed vertically. I've got Vista RC2 (5744)

Maybe the bug is within the application that saved the picture?

Human after all

Vista has a new system for codecs does it not? could be a slight bug with the JPG codec stability?

If I'd have to guess I'd say that Vista was getting confused by the conflicting info within the file.

Take a look at the file properties in Windows (I only have XP at hand), the summary page tells me that while it is a 667x1000 image... it is 72dpi horizontally and only 1dpi vertically.

Try resaving the file in another app or verifying the output of the app you are saving it from originally as having that sort of dpi conflict *can* cause issues depending on how the loader of the image handles it.

Aaahh.. I see it now... well found, dahat!

Hmm... Vista tries to respect the dpi values... interesting.. Cool

Same behaviour on my rc2. But when I press "start slide show" it is ok.

It's not just Vista, IIRC the .NET Framework works just the same way unless you tell it to handle things otherwise.

Wheres my head at?

Yesturday I found that this image displays very oddly in Vista.

It seems reducing its size and displaying it with a large white border.
It behaves like this in IE7, Photo Gallery, and as album art in WMP11.
Interestingly it displays at the correct size momentarily as it is being downloaded in IE.

That image displays the same way on XP... it appears to actually have the large white border around it.

I have the same issue on many photos, but I remember that I'd seen those picture fine before some time, bcz it shows thumnail ok for a moment and then become a bar.
