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.

  • 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:
      1. object is not null.
      2. object is an instance of class MediaSize.
      3. This media size attribute's X dimension is equal to object's X dimension.
      4. 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

    • getCategory

      public final Class<? extends Attribute> getCategory()
      Get the printing attribute class which is to be used as the "category" for this printing attribute value.

      For class MediaSize and any vendor-defined subclasses, the category is class MediaSize itself.

      Specified by:
      getCategory in interface Attribute
      Returns:
      printing attribute class (category), an instance of class java.lang.Class

    • getName

      public final String getName()
      Get the name of the category of which this attribute value is an instance.

      For class MediaSize and any vendor-defined subclasses, the category name is "media-size".

      Specified by:
      getName in interface Attribute
      Returns:
      attribute category name
