Scale( ) — scale an image to given dimensions

Synopsis

$image->Scale(geometry=>geometry,
                     
width=>integer,
                      
height=>integer)

Scale( ) will change the size of an image to the given dimensions. The dimensions may be specified either as absolute pixel sizes:

$image->Scale('300x300');      # scales the image to 300 pixels by 300 pixels

or by percentages for proportional scaling:

$image->Scale('300%x300%');    # makes the image three times larger
$image->Scale('300%');         # same thing

Use the Transform( ) method to scale an image and automatically apply an intelligent sharpening filter that will give better results than Scale( ) in most cases.
