1.91.2 (xp) - small bitmap no longer displayed

[klaus2]

First - congratulations for the new version .. cool, great!

.. but since 1.91.2 a small windows bitmap (from a develop package; "acGotoSystem.bmp"; looks like an icon; w 16, h 16; bits per plane 32; bits per pixel 32) is no longer displayed at all:
- not as thumbnail, not as preview, not as image in the viewer (the display area simply stays empty)
I cannot find it depends on an option, and don't believe it's by intention
?
I can send the sample by PM, if needed.

Hello !

• I assume it's related to the new "Tansparency" options which have been changed (moved in the View menu) in 1.91.2

klaus2, what are your settings for Files smaller than (Tools » Options... » Browser » File List)?

[klaus2]

oh .. yes (clo, thanks!), i needed to click
.. View >> preview >> use alpha channel
for to get back the "old" behaviour for preview and viewer - so far ok -

... but the thumbnail display area is still empty. How to fix that?
Separate option?

[klaus2]

-> XnTriq,
as now only the thumbnail display is "missing", do you still suspect some special thing in the Tools » Options... » Browser » File List options?
(there are so many, but i cannot detect something specific for the thumbnails)

Hello Mr. Librarian !

• A 32 BPP 16×16 pixels BMP is 1078 bytes… Do you think really that klaus2 has set smaller than that ?

Hm… I didn't test that yet, I don't use that colour-depth a lot, though now the icons are processed as 32 BPP…
- I'll check it.

Try to enable 'use trasnpanret index'?

Did you rebuild the folder thumbnails?

[klaus2]

hello,

already tried
- rebuild the folder thumbnails -> no impact
- enable 'use transparent index' -> no impact

With 1.91 it was still good (don't know about 1.91.1 since i don't have it)

I see the problem on a pc with XP .. on another one with w2k i have not the problem ...

Could you send me a sample file?

[klaus2]

i sent it ..

[xnview]

Your picture has a bad channel alpha.

Please uncheck (context menu on preview) 'use alpha channel' & 'use transparent index' and rebuild the thumbnails

[klaus2]

Hello Pierre,

yes, that helps. Thanks!

So what i needed in fact after unzip 1.91.2, was only to "rebuild thumbnails", _instead of_ checking those options.

Little piece of information still missing: what does this rebuild do? I would have expected that it recreates the cache. But actually i do not use the cache. So, what is rebuilded that makes this change persistent?

Best Regards!

You must have a cache file!

[klaus2]

Hello Pierre,

although of course i have a basic cache/xnview.db file (size 9k) which's datestamp obviously is updated by the rebuild command, i don't use this cache file for thumbnail's caching (=> [Cache] IsActive=0 in the inifle).
So, it's not a kind of matter that a cache information for a specific (*) file had been refreshed.
So, for understanding only, my question what the rebuild does, in that case.

The install proccedure had been: unzip the zip file in a _new_ directory; copy the "old" ini file 1.91 - with setting cache disable, and without the new transparent options - into that dir. Now i had the problem.

However, all works fine now. Btw Xnview is a wonderful compact, lean and fast software. I like it. Great compliments!

Many thanks!

(*) the sample file might appear to have a bad alpha channel; in fact such kind of bitmap files are oftenlly used as icon files for Delphi programs (they seem to have their own proprietaire transparent bitmap formats).
All those files (never cached) are displayed now as expected, after having applied the rebuild command once.
