public final class PrinterResolution extends ResolutionSyntax implements DocAttribute, PrintRequestAttribute, PrintJobAttribute
Class PrinterResolution is a printing attribute class that specifies an exact resolution supported by a printer or to be used for a print job. This attribute assumes that printers have a small set of device resolutions at which they can operate rather than a continuum.
PrinterResolution is used in multiple ways:
IPP Compatibility: The information needed to construct an IPP "printer-resolution"
attribute can be obtained by calling methods on the PrinterResolution object. The category name returned by getName()
gives the IPP attribute name.
DPCM, DPI
public PrinterResolution(int crossFeedResolution, int feedResolution, int units)
Construct a new printer resolution attribute from the given items.
crossFeedResolution
- Cross feed direction resolution.feedResolution
- Feed direction resolution.units
- Unit conversion factor, e.g. ResolutionSyntax.DPI
or ResolutionSyntax.DPCM
.IllegalArgumentException
- (unchecked exception) Thrown if crossFeedResolution < 1
or feedResolution < 1
or units < 1
.public boolean equals(Object object)
Returns whether this printer resolution 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 PrinterResolution. object
's cross feed direction resolution. object
's feed direction resolution. equals
in class ResolutionSyntax
object
- Object to compare to.object
is equivalent to this printer resolution attribute, false otherwise.Object.hashCode()
, HashMap
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 PrinterResolution, the category is class PrinterResolution itself.
getCategory
in interface Attribute
java.lang.Class
.public final String getName()
Get the name of the category of which this attribute value is an instance.
For class PrinterResolution, the category name is "printer-resolution"
