JRE 8 rt.jar - javax.* Package Source Code
JRE 8 rt.jar is the JAR file for JRE 8 RT (Runtime) libraries. JRE (Java Runtime) 8 is the runtime environment included in JDK 8. JRE 8 rt.jar libraries are divided into 6 packages:
com.* - Internal Oracle and Sun Microsystems libraries java.* - Standard Java API libraries. javax.* - Extended Java API libraries. jdk.* - JDK supporting libraries. org.* - Third party libraries. sun.* - Old libraries developed by Sun Microsystems.

This class can be used to query * the acceptable values for a supposed print job, and to request an area * within the constraints of the printable area to be used in a print job. * <p> * To query for the printable area, a client must supply a suitable context. * Without specifying at the very least the size of the media being used * no meaningful value for printable area can be obtained. * <p> * The attribute is not described in terms of the distance from the edge * of the paper, in part to emphasise that this attribute is not independent * of a particular media, but must be described within the context of a * choice of other attributes. Additionally it is usually more convenient * for a client to use the printable area. * <p> * The hardware's minimum margins is not just a property of the printer, * but may be a function of the media size, orientation, media type, and * any specified finishings. * <code>PrintService</code> provides the method to query the supported * values of an attribute in a suitable context : * See {@link javax.print.PrintService#getSupportedAttributeValues(Class,DocFlavor, AttributeSet) PrintService.getSupportedAttributeValues()} * <p> * The rectangular printable area is defined thus: * The (x,y) origin is positioned at the top-left of the paper in portrait * mode regardless of the orientation specified in the requesting context. * For example a printable area for A4 paper in portrait or landscape * orientation will have height {@literal >} width. * <p> * A printable area attribute's values are stored * internally as integers in units of micrometers (µm), where 1 micrometer * = 10<SUP>-6</SUP> meter = 1/1000 millimeter = 1/25400 inch. This permits * dimensions to be represented exactly to a precision of 1/1000 mm (= 1 * µm) or 1/100 inch (= 254 µm). If fractional inches are expressed in * negative powers of two, this permits dimensions to be represented exactly to * a precision of 1/8 inch (= 3175 µm) but not 1/16 inch (because 1/16 inch * does not equal an integral number of µm). * <p> * <B>IPP Compatibility:</B> MediaPrintableArea is not an IPP attribute. */ public final class MediaPrintableArea implements DocAttribute, PrintRequestAttribute, PrintJobAttribute { private int x, y, w, h; private int units; private static final long serialVersionUID = -1597171464050795793L; /** * Value to indicate units of inches (in).
