A default [method get_seamless_image] implementation is provided for libraries that do not provide seamless noise. This function requests a larger image from the [method get_image] method, reverses the quadrants of the image, then uses the strips of extra width to blend over the seams. Inheriting noise classes can optionally override this function to provide a more optimal algorithm. </description> <tutorials> </tutorials> <methods> <method name="get_image" qualifiers="const"> <return type="Image" /> <param index="0" name="width" type="int" /> <param index="1" name="height" type="int" /> <param index="2" name="invert" type="bool" default="false" /> <param index="3" name="in_3d_space" type="bool" default="false" /> <param index="4" name="normalize" type="bool" default="true" /> <description> Returns an [Image] containing 2D noise values.
