Name

geometry — shortcut for specifying width and height

Synopsis

$image->Set(geometry=>string)
$image->Get('geometry')

The geometry attribute is a convenience name that allows you to specify the width and height, or a region of an image with an offset in a single string. For example:

geometry=>'640x800'

is equivalent to:

width=>640, height=>800

To refer to a 20 × 20 region of pixels starting at coordinate (100, 150), use:

geometry=>'20x20+100+150'
