Dimensions

Inheritance: java.lang.Object

public class Dimensions

Represents the linear dimensions (width and height) of one raster rectangular image in arbitrary unit. Immutable struct.

Constructors

Constructor Description
Dimensions(int width, int height) Creates a new instance from specified width and height

Methods

Method Description
getWidth() Returns width of the image
getHeight() Returns height of the image
isSquare() Determines whether specified ‘Dimensions’ represents square, i.e.
getArea() Returns an area (Width x Height)
isEmpty() Determines whether this “Dimensions” instance is empty and default, i.e.
getAspectRatio() Aspect ratio of this dimensions as width/height
proportionallyResizeForNewWidth(int targetWidth) Creates and returns new “Dimensions” instance, which is proportionally resized from current, based on specified width
proportionallyResizeForNewHeight(int targetHeight) Creates and returns new “Dimensions” instance, which is proportionally resized from current, based on specified height
equals(Dimensions other) Determines whether this instance is equal with specified “Dimensions” instance
equals(Object obj) Determines whether this instance is equal with specified uncasted object, which presumably is another “Dimensions” instance
hashCode() Returns a hashcode for this instance, which cannot be changed during its lifetime
op_Equality(Dimensions first, Dimensions second) Checks whether two “Dimensions” values are equal, i.e.
op_Inequality(Dimensions first, Dimensions second) Checks whether two “Dimensions” values are not equal, i.e.
toString() Returns a string representation of this “Dimensions”
deepClone() Returns a full copy of this instance
getEmpty() Returns an empty Dimensions instance
fromSize(Dimension size) Generates and returns a new instance from specified System.Drawing.Size instance

Dimensions(int width, int height)

public Dimensions(int width, int height)

Creates a new instance from specified width and height

Parameters:

Parameter Type Description
width int Width of image
height int Height of image

getWidth()

public final int getWidth()

Returns width of the image

Returns: int

getHeight()

public final int getHeight()

Returns height of the image

Returns: int

isSquare()

public final boolean isSquare()

Determines whether specified ‘Dimensions’ represents square, i.e. if width is equal to height

Returns: boolean

getArea()

public final long getArea()

Returns an area (Width x Height)

Returns: long

isEmpty()

public final boolean isEmpty()

Determines whether this “Dimensions” instance is empty and default, i.e. it doesn’t store correct width and height

Returns: boolean

getAspectRatio()

public final Ratio getAspectRatio()

Aspect ratio of this dimensions as width/height

Returns: Ratio

proportionallyResizeForNewWidth(int targetWidth)

public final Dimensions proportionallyResizeForNewWidth(int targetWidth)

Creates and returns new “Dimensions” instance, which is proportionally resized from current, based on specified width

Parameters:

Parameter Type Description
targetWidth int New target width, that will be present in resultant Dimension

Returns: Dimensions - New “Dimensions” instance with specified target width and proportionally resized height

proportionallyResizeForNewHeight(int targetHeight)

public final Dimensions proportionallyResizeForNewHeight(int targetHeight)

Creates and returns new “Dimensions” instance, which is proportionally resized from current, based on specified height

Returns: Dimensions - New “Dimensions” instance with specified target height and proportionally resized width

equals(Dimensions other)

public final boolean equals(Dimensions other)

Determines whether this instance is equal with specified “Dimensions” instance

Parameters:

Parameter Type Description
other Dimensions Other “Dimensions” instance to check on equality

Returns: boolean - True if are equal, false if are not equal

equals(Object obj)

public boolean equals(Object obj)

Determines whether this instance is equal with specified uncasted object, which presumably is another “Dimensions” instance

Parameters:

Parameter Type Description
obj java.lang.Object Other object, that is presumably of “Dimensions” type, that should be checked on equality with this
