Image Display
Caption
Allows customizing the caption (if any) to display during image playback. This uses the expression language.
Effect
Allows effects, like optimize, black & white, sepia, etc. Can also be controlled using the W and E keys, or the on screen dispaly during image playback.
Shrink large images to fit display
If an image is too large to fit on the screen, this will shrink it to fit on the screen.
Stretch small images to fill display
If an image is smaller than the screen, this option will stretch it so that it fills the entire screen.
Slideshow
Disable transitions on manual image changes
This option makes it so no animation is performed when switching images manually (using left / right, etc.)
Pan & zoom during slideshows
This creates an animated Ken Burn's style pan & zoom effect when showing a slideshow. This option can also be controlled using the on screen display.
Slideshow duration
Allows controlling the amount of time each image should be shown during a slideshow.
RAW Settings
RAW Decode Quality
Allows tuning the RAW decoder for speed or quality.
RAW Cache
By default, RAW images are cached after they are decoded. Then, future loads will use the cached image. This greatly improves performance.
