[Solved/Fixed] Lister tolerant image/file format detection

This is because TC analysizes the Header of the file and sees that its NOT an JPEG

I would think so too - but then I don't understand that the ImgView plugin comes up with an error message:

---------------------------
error
---------------------------
Crash in plugin ImgView.wlx:

External exception EEDFADE
---------------------------
OK Annuller
---------------------------

Followed by a message that is generated by TC itself (if I press Escape, not Enter):

---------------------------
Total Commander
---------------------------
Cannot change Visible in OnShow or OnHide.
Please report this error to the Author,
with a description of what you were doing when this error occured!
Continue execution?
---------------------------
Ja Nej
---------------------------

And if "TC analysizes the Header of the file", how come that some people here (Lefteous and Horst.Epp) can see the file in SGViewer

I think Lister should not analyse any file headers.
Once I asked Chisler to add EMZ/WMZ formats support.
This is an ususlly gzipped emf/wmf file with cutted original extension (name.emz/name, name is emf file).
These files creates MS Word when saving file with pics as HTML and in Word's HTML saving options enabled VML.
Well, so Christian said that this cannot be implemented because of Lister cannot recoginze format of file if it has no extension.
I think this is valid for files with any extension too.
For your case maybe this can help:

Code: Select all

[Lister]
IviewAdditionalTypes=*.jpg

If not - I think there is a bug in Lister.

I think Lister should not analyse any file headers.

Agree. This may be OK, if maybe another viewer could show the file, but not, if it's the last chance to show or not show the file (like in the case of IV/XNV).

For your case maybe this can help:

Code: Select all

[Lister]
IviewAdditionalTypes=*.jpg

Good idea, thanks. This works, when the file is renamed to *.jpg_ (and IviewAdditionalTypes is set accordingly).
Unfortunately the picture is only displayed with file name *.jpg_ - NOT with *.jpg (even with IviewAdditionalTypes=*.jpg).

If not - I think there is a bug in Lister.

Agree. Other workarounds are still welcome until there is a solution.

2Lefteous:

Using the the Lister plug-in SGViewer your test image is displayed fine.

Now I found out, why SGViewer wasn't displaying the file on my system: without ijl15.dll it doesn't display it, after activating the use of this library the file is also displayed by SGViewer.
This is a good workaround, as long as the file is still not passed to XNView/IrfanView.

If not - I think there is a bug in Lister.

Agree. Other workarounds are still welcome until there is a solution.

Yes I'm using this library together with SGViewer.

Sorry, I didn't wrote a link to report here.

This is not a bug, but Ghisler will try to solve the problem.

... why SGViewer wasn't displaying the file on my system: without ijl15.dll it doesn't display it...

Thanks for that info - now it also works in my SGViewer

Fixed in TC 7.01: using this workaround now the problematic files can also be displayed in Xn/IrfanView :

Code: Select all

[Lister]
IviewAdditionalTypes=*.jpg_ *.jpg
