Trying to work with images and the Image cache...

With the cdART Manager script there are times that images need to be updated, the Image cache in XBMC makes this difficult. I don't think there is a clear way to visually update the image.

Except for the following ways....
  1. Wait for 24hrs(or there abouts I think)
  2. Over write the thumbnail and force a Reload of the skin.

The second option is what I think the Logo Downloader does(not 100% sure) But this works fine for the skin but does nasty things to my script. Using the builtin command XBMC.ReloadSkin() (xbmc.executebuiltin( 'XBMC.ReloadSkin()' )) causes the addon's skin to deinitialize(and also the main skin) then try to re-initialize. This does not work.. XBMC seems to build the path to the addon's skin incorrectly and does not load the addons skin but kicks back to the MyPrograms.xml file, with the addon still running(but no way to shut it down(besides the obvious restart XBMC) )

The Line:
Code:
ERROR: LoadXML: Unable to load skin file /usr/share/xbmc/addons/skin.confluence/720p/home/xbmc/.xbmc/addons/script.cdartmanager/resources/skins/Default/720p/script-cdartmanager.xml

is the error due to the incorrect path(or the addon's skin path added to the skin path)

It would be nice to have a way to trigger a refresh of the image cache as well with out having to refresh the skin(if that is possible)

The xml loading issue looks like a bug, yeah. Please post on trac with a solid way to reproduce.

For refreshing images in the imagecache, the problem is that current nothing exposes the imagecache at all - i.e. it's entirely automatic.

What sort of image updating are you doing (and why), so I can get a handle on what we need to expose.
Always read the XBMC online-manual, FAQ and search the forum before posting.

For my script, cdART Manager, the user can download different types of artwork(cdART, cover Art, Artist Fanart, clearLOGOs) from the website fanart.tv. The script displays the local artwork(whenever possible). Sometimes there is local artwork that has an updated artwork on the site, if the user downloads this new image, the script saves it to the exact same file name as the old artwork. I know this image will eventually be refreshed into the imagecache, it would be nice to request an update so the image is proper. I don't know how difficult it would be to, the script to pass a command something like 'xbmc.updateimageCache( path to image)'

I had this problem too... Anyone found out if this is a bug or if there is any workaround?

Thanks

We are now using the same method as logo-downloader:
1. remove the cached file and replace it with new one
2. XBMC.ReloadSkin()

I was thinking of maybe directly removing the entry from the cache6.db so when the image is loaded it will be refresh or doesn't this work that way?
The solution Giftie offers would be much better if possible.
