Advanced Output Options allow you to change some of AutoCollage's operational parameters.

The Advanced Output Options section is located on the AutoCollage Options Output tab.
To bring up the Advanced Output Options section:
The Top-ranked image slider allows you to choose how much larger to make the interesting region in the highest ranked image, relative to other selected images. The Second ranked image slider does the same for the second ranked image.
The Image Overlap slider allows you to specify the minimum overlap factor for adjacent images before boundary generation and blending. A smaller number means that some adjacent images may have abrupt transitions. A larger number tells AutoCollage to ensure adjacent images overlap enough to allow interesting boundaries and blends.
To set each of these options, select the slider and drag it to the desired value. A tooltip will tell you what value you've chosen.
If at any time you're unhappy with the values you chose, simply click on the Reset button to restore the default Advanced Output Option settings.
