Before creating a collage, AutoCollage must choose which images to use. It does this by examining each of the images it has loaded, ranking them from most interesting to least interesting, and preferring the highest ranked images for inclusion in the collage.
Ranked images can be divided into four categories:
For example, if you make a 7-image collage from a folder with 50 images, then the 3rd through 7th ranked images are included images, and the 8th through 50th ranked images are excluded images.
To review and modify image ranking, enable ranking information display and manual ranking via advanced input options. This will allow you to review and influence the ranking of images for collage creation.
The 1st and 2nd ranked images have an icon with their rank superimposed on the top of them.
Other included images are rendered normally, but may have another icon superimposed when they are zoomed. These icons are shown and explained in Changing Image Ranking.
Excluded images - those which will not be in the created collage - are rendered with diagonal lines across them.
Since the number of images included in the collage is determined by the Image Count Slider, changing this slider will affect the set of included and excluded images.
