Interfaces

public interface operator (==)

Returns whether images are equal.

  • public pure elemental function dm_image_equals(image1, image2) result(equals)

    Returns .true. if given images are equal.

    Arguments

    The first image.
    type(image_type), intent(in) :: image2

    The second image.

    Return Value logical


Derived Types

type, public ::  image_type

Image type.

Components

Type Visibility Attributes Name Initial
character(len=IMAGE_ID_LEN), public :: id = ' '

Image id (UUIDv4).
character(len=NODE_ID_LEN), public :: node_id = ' '

Node id.
character(len=SENSOR_ID_LEN), public :: sensor_id = ' '

Functions

public pure elemental function dm_image_equals(image1, image2) result(equals)

Returns .true. if given images are equal.

Arguments

Type IntentOptional Attributes Name
