Class MediaSize

java.lang.Object

javax.print.attribute.Size2DSyntax

javax.print.attribute.standard.MediaSize

All Implemented Interfaces:: Serializable, Cloneable, Attribute

public class MediaSize extends Size2DSyntax implements Attribute

Class MediaSize is a two-dimensional size valued printing attribute class that indicates the dimensions of the medium in a portrait orientation, with the X dimension running along the bottom edge and the Y dimension running along the left edge. Thus, the Y dimension must be greater than or equal to the X dimension. Class MediaSize declares many standard media size values, organized into nested classes for ISO, JIS, North American, engineering, and other media.

MediaSize is not yet used to specify media. Its current role is as a mapping for named media (see MediaSizeName). Clients can use the mapping method MediaSize.getMediaSizeForName(MediaSizeName) to find the physical dimensions of the MediaSizeName instances enumerated in this API. This is useful for clients which need this information to format & paginate printing.

Constructor Details

MediaSize

public MediaSize(float x, float y, int units)

Construct a new media size attribute from the given floating-point values.

Parameters:: x - X dimension; y - Y dimension; units - unit conversion factor, e.g. Size2DSyntax.INCH or Size2DSyntax.MM
Throws:: IllegalArgumentException - if x < 0 or y < 0 or units < 1 or x > y

MediaSize

public MediaSize(int x, int y, int units)

Construct a new media size attribute from the given integer values.

Parameters:: x - X dimension; y - Y dimension; units - unit conversion factor, e.g. Size2DSyntax.INCH or Size2DSyntax.MM
Throws:: IllegalArgumentException - if x < 0 or y < 0 or units < 1 or x > y

MediaSize

public MediaSize(float x, float y, int units, MediaSizeName media)

Construct a new media size attribute from the given floating-point values.

Parameters:: x - X dimension; y - Y dimension; units - unit conversion factor, e.g. Size2DSyntax.INCH or Size2DSyntax.MM; media - a media name to associate with this MediaSize
Throws:: IllegalArgumentException - if x < 0 or y < 0 or units < 1 or x > y

MediaSize

Method Details

getMediaSizeName

public MediaSizeName getMediaSizeName()

Get the media name, if any, for this size.

Returns:: the name for this media size, or null if no name was associated with this size (an anonymous size)

getMediaSizeForName

public static MediaSize getMediaSizeForName(MediaSizeName media)

Get the MediaSize for the specified named media.

Parameters:: media - the name of the media for which the size is sought
Returns:: size of the media, or null if this media is not associated with any size

findMedia

public static MediaSizeName findMedia(float x, float y, int units)

The specified dimensions are used to locate a matching MediaSize instance from amongst all the standard MediaSize instances. If there is no exact match, the closest match is used.

The MediaSize is in turn used to locate the MediaSizeName object. This method may return null if the closest matching MediaSize has no corresponding Media instance.

This method is useful for clients which have only dimensions and want to find a Media which corresponds to the dimensions.

Parameters:: x - X dimension; y - Y dimension; units - unit conversion factor, e.g. Size2DSyntax.INCH or Size2DSyntax.MM
Returns:: MediaSizeName matching these dimensions, or null
Throws:: IllegalArgumentException - if x <= 0, y <= 0, or units < 1

equals

public boolean equals(Object object)

Returns whether this media size attribute is equivalent to the passed in object. To be equivalent, all of the following conditions must be true:

object is not null.
object is an instance of class MediaSize.
This media size attribute's X dimension is equal to object's X dimension.
This media size attribute's Y dimension is equal to object's Y dimension.

Overrides:

equals in class Size2DSyntax

Parameters:

object - Object to compare to

Returns:

true if object is equivalent to this media size attribute, false otherwise
