Enum Class VipsBlendMode

java.lang.Object
java.lang.Enum<VipsBlendMode>
app.photofox.vipsffm.enums.VipsBlendMode
All Implemented Interfaces:
VEnum, VNamedEnum, Serializable, Comparable<VipsBlendMode>, Constable
public enum VipsBlendMode extends Enum<VipsBlendMode> implements VNamedEnum

The various Porter-Duff and PDF blend modes. See VImage.composite(java.lang.foreign.Arena, java.util.List<app.photofox.vipsffm.VImage>, java.util.List<java.lang.Integer>, app.photofox.vipsffm.VipsOption...), for example.

The Cairo docs have a nice explanation of all the blend modes.

The non-separable modes are not implemented.

  • Enum Constant Details

    • BLEND_MODE_CLEAR

      public static final VipsBlendMode BLEND_MODE_CLEAR
      where the second object is drawn, the first is removed

    • BLEND_MODE_SOURCE

      public static final VipsBlendMode BLEND_MODE_SOURCE
      the second object is drawn as if nothing were below

    • BLEND_MODE_OVER

      public static final VipsBlendMode BLEND_MODE_OVER
      the image shows what you would expect if you held two semi-transparent slides on top of each other

    • BLEND_MODE_IN

      public static final VipsBlendMode BLEND_MODE_IN
      the first object is removed completely, the second is only drawn where the first was

    • BLEND_MODE_OUT

      public static final VipsBlendMode BLEND_MODE_OUT
      the second is drawn only where the first isn't

    • BLEND_MODE_ATOP

      public static final VipsBlendMode BLEND_MODE_ATOP
      this leaves the first object mostly intact, but mixes both objects in the overlapping area

    • BLEND_MODE_DEST

      public static final VipsBlendMode BLEND_MODE_DEST
      leaves the first object untouched, the second is discarded completely

    • BLEND_MODE_DEST_OVER

      public static final VipsBlendMode BLEND_MODE_DEST_OVER
      like OVER, but swaps the arguments

    • BLEND_MODE_DEST_IN

      public static final VipsBlendMode BLEND_MODE_DEST_IN
      like IN, but swaps the arguments

    • BLEND_MODE_DEST_OUT

      public static final VipsBlendMode BLEND_MODE_DEST_OUT
      like OUT, but swaps the arguments

    • BLEND_MODE_DEST_ATOP

      public static final VipsBlendMode BLEND_MODE_DEST_ATOP
      like ATOP, but swaps the arguments

    • BLEND_MODE_XOR

      public static final VipsBlendMode BLEND_MODE_XOR
      something like a difference operator

    • BLEND_MODE_ADD

      public static final VipsBlendMode BLEND_MODE_ADD
      a bit like adding the two images

    • BLEND_MODE_SATURATE

      public static final VipsBlendMode BLEND_MODE_SATURATE
      a bit like the darker of the two

      public static final VipsBlendMode BLEND_MODE_MULTIPLY
      at least as dark as the darker of the two inputs

    • BLEND_MODE_SCREEN

      public static final VipsBlendMode BLEND_MODE_SCREEN
      at least as light as the lighter of the inputs

    • BLEND_MODE_OVERLAY

      public static final VipsBlendMode BLEND_MODE_OVERLAY
      multiplies or screens colors, depending on the lightness

    • BLEND_MODE_DARKEN

      public static final VipsBlendMode BLEND_MODE_DARKEN
      the darker of each component

    • BLEND_MODE_LIGHTEN

      public static final VipsBlendMode BLEND_MODE_LIGHTEN
      the lighter of each component

    • BLEND_MODE_COLOUR_DODGE

      public static final VipsBlendMode BLEND_MODE_COLOUR_DODGE
      brighten first by a factor second

    • BLEND_MODE_COLOUR_BURN

      public static final VipsBlendMode BLEND_MODE_COLOUR_BURN
      darken first by a factor of second

    • BLEND_MODE_HARD_LIGHT

      public static final VipsBlendMode BLEND_MODE_HARD_LIGHT
      multiply or screen, depending on lightness

    • BLEND_MODE_SOFT_LIGHT

      public static final VipsBlendMode BLEND_MODE_SOFT_LIGHT
      darken or lighten, depending on lightness

    • BLEND_MODE_DIFFERENCE

      public static final VipsBlendMode BLEND_MODE_DIFFERENCE
      difference of the two

    • BLEND_MODE_EXCLUSION

      public static final VipsBlendMode BLEND_MODE_EXCLUSION
      somewhat like DIFFERENCE, but lower-contrast

    • BLEND_MODE_LAST

      public static final VipsBlendMode BLEND_MODE_LAST

  • Field Details

  • Method Details

    • values

      public static VipsBlendMode[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static VipsBlendMode valueOf(String name)
