Problem: IrfanView crashes, if I´ll save 'panoramic image'

[optimo]

Windows XP, IrfanView 4.10

Hello together,

at first: I am very content with IrfanView, it works fanstastic and trouble-free, up to the following problem.

Please, who can give me an advice in that "headache":

The problem:
If I construct a "panoramic image" and I will save that constructed image, very often IrfanView crashes, if I click "Save".

This happens on my PC only with IrfanView!

My question:
Do I something wrong? Or is it an IrfanView-specific problem?
What´s to do?

I would be very glad, if anyone could help me.

Thank you in advance

Not enough detail. How big is this image? Are all of the images you are joining the same size, colour depth, and file format? What file format are you trying to save it in? How much RAM do you have fitted?

[optimo]

Thank you for your answer.

1.) I can´t say something about details, because, when it crashes, I don´t have exact facts of the constructed picture. The crash ends in the view of the desktop!

2.) If I interpret right your question, there is a limitation.
So I would ask vice versa: Where do I find something about the limiting factors?
That would be of cause very helpful!

If you cannot tell us the details, then we cannot reproduce the problem, and we cannot find out what the limitations are. For me, creating panorama images does not cause a crash at all. Even if the images I am joining are huge, it doesn't join them all, but it doesn't crash.

Others can only confirm the alleged bug if you can provide sufficient details of under what circumstances it happens.

Hi,

welcome here

I´ve no problem creating large panorama images:

I created an image with 2048x10624 pixels. No problem.

Please give us detailed information about your pc + image resolution.

thx,

steve

Thank you for your statements and troubles to help me.

Of cause I know that it is necessary to have facts to find out the problem.
My problem to give specific data I have explained above.
But I can assure that I have these problems - strangely in the moment it functions faultlessly. In this I see from my point of view a kind of instability.

The tenor of my question was in the first instance, if in this relation defects of the system are known.

Then - this question is still without reply - are there any limitations for the creation of "panoramic images" on the part of the system "IrfanView"?

Hi optimo,

We have understood you have that problem.

Please give us detailed information about your pc + image resolution.

Can you give information about your PC?

Laurent

[optimo]

Ok. Tell me what you want to know about my PC.
Image resolution I don´t understand, resp. I have told you the problem above; if you mean 'screen resolution': 1280 x 1024.

But my question concerning the limitations are still unanswered!

thx

Hi,

For me IrfanView uses about 4.092 K of RAM (see windows taskmanager under iview32.exe). When adding some pictures the process uses about 7.400 K.

So you can exclude RAM as a limiting factor.

But my question concerning the limitations are still unanswered!

And, vice versa, Bhikkhu's simple questions about "..the same size, colour depth, and file format?.." are still unanswered too.
But let's try to exclude more, because it's sometimes faultlessly and sometimes a crash.
Is there an auto-virusscanner running when this happens ?
Are the bitmaps involved loaded by other applications as well on that moment ?

Hello Sam_Zen,

thank you for your answer.

And, vice versa, Bhikkhu's simple questions about "..the same size, colour depth, and file format?.." are still unanswered too.

Sorry, but this is not correct: twice I already have said, that I have no data after the crashes and anything from memory is unprecise!

But let's try to exclude more, because it's sometimes faultlessly and sometimes a crash.
Is there an auto-virusscanner running when this happens ?

Yes I have a virus-scanner working

Are the bitmaps involved loaded by other applications as well on that moment ?

No

I have noticed this bug for several years across a number of IrfanView versions.

For me, it mostly happens when I add images to the Panorama dialog one at a time using the "Add..." button (vs. CTRL-clicking to select several images at once). It's hard to replicate on purpose but it happens at least half the time when I browse one by one with the "Add..." button, which is sometimes more convenient than CTRL-click.

The size of the images to be merged tends to be small (320x240 or so), so I don't think it's a function of overloading memory, etc. I have noticed the bug when using Windows XP and Vista on various PCs, and I think it's not platform-dependent.

Update: I just confirmed the bug with v4.27 using some 300x200 BMP images when I added them to the list using the "Add..." button (not the CTRL-click method).

Is the crash you experience repeatable? I see the following situation:

- You work on creating a Panorama and IrfanView crashes
- You then bring IrfanView back up and work on the same Panorama again

Does it work the second time you try it, or does it crash again?

When it crashes, could you write down the messages you get and post them here? If you're getting a Program Exception or something like that, the specifics might not be that helpful but they will definitely help confirm what is going on. I notice that you're probably not a native English speaker and so it's possible that what we read is different from what you meant. That's why the specifixcs of what happened is important. I understand your memory is imperfect (I think that was how you described it), so the next time it happens, please write down (or copy/paste if possible) what you were doing, what messages you received, and what happened when you tried the same operation again.

Cheers, Neil.
