No thumbnails for a lot of files. #31

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I have thumbnail generation by sagethumbs enabled for PDF and EPS files. For 
some of them, the thumbnails are generated, but for many files no thumbnail is 
generated. 

It is not an issue with the files, as copies of the same file may occur with 
and without thumbnail.

Sometimes folders with many files have thumbnails for all of them, sometimes 
folders don't have a single thumbnail, sometimes files with and without 
thumbnails are mixed. 

Also, I observed thumbnails starting to appear file-by-file after changing the 
magnification of the thumbnails (ctrl+mousewheel), but I couldn't reproduce it 
in other folders. 

Changing the settings (maximum file size 500 MB, clearing cache, use integrated 
thumbnails, cache thumbnails, disabling context menu entry) did not change the 
behaviour. 

I am using Sagethumb 2.0.0.15 on Windows 7 Home Premium 64bit.

For PDF I suggest you using native Adobe Reader thumbnailer with fixes:

How much files in problem folders?

BTW Increasing maximum file size to such huge values is not a good idea, for 
big files thumbnail generation can be VERY slow. Especially when its PostScript 
files opened by external GhostScript library (which I can not fix).

For an unknown reason, I can no longer reproduce the problem. The only change I 
made since was reducing the maximum file size back to 20 MB, but no files 
larger than 20 MB were involved in the first place. Also, the problem occurred 
before setting the maximum size to a large number.

Windows caches thumbnails also by itself, so after changing some options actual 
changes may be not instant. Sometimes its better to clean cache and/or reboot 
Windows after changes.
