Imagick::thumbnailImage

Changes the size of an image to the given dimensions and removes any associated profiles. The goal is to produce small, low cost thumbnail images suited for display on the Web. If TRUE is given as a third parameter then columns and rows parameters are used as maximums for each side. Both sides will be scaled down until they match or are smaller than the parameter given for the side.

Note: The behavior of the parameter bestfit changed in Imagick 3.0.0. Before this version given dimensions 400x400 an image of dimensions 200x150 would be left untouched. In Imagick 3.0.0 and later the image would be scaled up to size 400x300 as this is the "best fit" for the given dimensions. If bestfit parameter is used both width and height must be given.
