Class VSource

java.lang.Object

app.photofox.vipsffm.VSource

public final class VSource
extends Object

Represents a VipsSource, boxed to avoid exposing its raw MemorySegment

Method Summary

Modifier and Type	Method	Description
boolean	equals(Object o)
MemorySegment	getUnsafeAddress()	Deprecated, for removal: This API element is subject to removal in a future version. See getUnsafeStructAddress()
MemorySegment	getUnsafeStructAddress()	Gets the raw MemorySegment (C pointer) for this VipsSource struct The memory address' lifetime is bound to the scope of the arena that created it Usage of the memory address is strongly discouraged, but it is available if some functionality is missing, and you need to use it with VipsHelper
int	hashCode()
static VSource	newFromBlob(Arena arena, VBlob blob)	Create a new VSource from a VBlob, usually received from a Vips operation
static VSource	newFromBytes(Arena arena, byte[] bytes)	Create a new VSource directly from some bytes Note that this makes a full copy of the data, which is inefficient - prefer VImage.newFromFile(Arena, String, VipsOption...) and friends
static VSource	newFromDescriptor(Arena arena, int descriptor)	Create a new VSource from a file descriptor
static VSource	newFromFile(Arena arena, String filename)	Create a new VSource from a file path
static VSource	newFromOptions(Arena arena, String options)
