Rebuild Thumbnails¶
The digiKam Maintenance Options to Rebuild Thumbnails¶
digiKam automatically generates and maintains thumbnails, but the Rebuild Thumbnail tool might be required if you have worked on your images with other applications or if you have changed the thumbnail size.
From , the option Use Large Thumbnail Size for High Screen Resolution can be turned on to render Icon-View with a large thumbnail size suitable for use on a 4K monitor. By default this option is turned off and the maximum thumbnail size is limited to 256x256 pixels.
When this option is enabled, thumbnail size can be extended to 512x512 pixels. This option will increase the size of the thumbnail database and will use more system memory. digiKam needs to be restarted for this option to take effect, and this Rebuild Thumbnails tool needs to be run over all collections.

重要
digiKam stores thumbnails in the database using the wavelet-compressed PGF format, but large collections can still generate huge thumbnail databases. Take care to use a sufficiently large storage media with a large amount of available space to store the database.

The Scan options from speed up the process in the first case or if you just added pictures to your collection.
While the rebuild thumbnails process is underway, a progress indicator is displayed in the bottom right corner of the main window.
