Resolution

class Resolution
kotlin.Any
   ↳ android.print.PrintAttributes.Resolution

This class specifies a supported resolution in DPI (dots per inch). Resolution defines how many points with different color can be placed on one inch in horizontal or vertical direction of the target media. For example, a printer with 600 DPI can produce higher quality images the one with 300 DPI resolution.

Summary

Public constructors
Resolution(id: String, label: String, horizontalDpi: Int, verticalDpi: Int)

Public methods
Boolean
equals(other: Any?)

Indicates whether some other object is "equal to" this one.

Int

Gets the horizontal resolution in DPI (dots per inch).

String

Gets the unique resolution id.

Resolution

Added in API level 19
Resolution(
    id: String,
    label: String,
    horizontalDpi: Int,
    verticalDpi: Int)

Creates a new instance.

Parameters
id String: The unique resolution id. It is unique amongst other resolutions supported by the printer. This value cannot be null.
label String: The localized human readable label. This value cannot be null.
horizontalDpi Int: The horizontal resolution in DPI (dots per inch). Value is 1 or greater
verticalDpi Int: The vertical resolution in DPI (dots per inch). Value is 1 or greater
Exceptions
java.lang.IllegalArgumentException If the id is empty or the label is empty or the horizontalDpi is less than or equal to zero or the verticalDpi is less than or equal to zero.

Public methods

equals

Added in API level 19
fun equals(other: Any?): Boolean

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
obj This value may be null.
Return
Boolean true if this object is the same as the obj argument; false otherwise.

getHorizontalDpi

Added in API level 19
fun getHorizontalDpi(): Int

Gets the horizontal resolution in DPI (dots per inch).

Return
Int The horizontal resolution. Value is 1 or greater

getId

Added in API level 19
fun getId(): String

Gets the unique resolution id. It is unique amongst other resolutions supported by the printer.

This id is defined by the client that generated the resolution instance and should not be interpreted by other parties.

Return
String The unique resolution id. This value cannot be null.

getLabel

Added in API level 19
fun getLabel(): String

Gets the resolution human readable label.

Return
String The human readable label. This value cannot be null.

getVerticalDpi

Added in API level 19
fun getVerticalDpi(): Int

Gets the vertical resolution in DPI (dots per inch).

Return
Int The vertical resolution. Value is 1 or greater

hashCode

Added in API level 19
fun hashCode(): Int
Return
Int a hash code value for this object.

toString

Added in API level 19
fun toString(): String
Return
String a string representation of the object.
