Gallery styles in FotoBilder can use different thumbnail settings to produce a specific effect, like using a grid of 100x100 thumbnails all centered around a large 'preview' image. For this, FotoBilder offers four crop settings:
- None (default)
In most cases, thumbnails will simply scale down to fit the thumbnail dimensions, keeping the picture's original aspect ratio
- Crop
Cropped (using the exact crop region), then scaled down to fit in the thumbnail dimensions using the crop region aspect ratio.
- Stretch
Stretched exactly to the thumbnail dimensions using the crop region.
- Zoom
Using the crop region's focus point, zoomed thumbnails will use the thumbnail's dimensions and fill the thumbnail with the proper aspect-ratio.
and two thumbnail color settings:
- Grey scale
Picture colors are set to grey scale for thumbnail image
- Negate
- The thumbnail will use the inverse of the picture's colors
In summary, with a crop region & focus point, different galleries can all share the same crop/focus data and still have very different looking thumbnails.
