Class VTarget

java.lang.Object

app.photofox.vipsffm.VTarget

public class VTarget
extends Object

Represents a VipsTarget, boxed to avoid exposing its raw MemorySegment

Method Summary

Modifier and Type	Method	Description
final boolean	equals(Object o)
VBlob	getBlob()	Only valid for memory-backed targets (eg via newToMemory(Arena)) Returns the contents of the backing VBlob
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 VipsTarget 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 VTarget	newToDescriptor(Arena arena, int descriptor)	Create a new target pointed at a file descriptor This target can be used with (for example) VImage.writeToTarget(VTarget, String, VipsOption...)
static VTarget	newToFile(Arena arena, String filename)	Create a new target pointed at an output file This target can be used with (for example) VImage.writeToTarget(VTarget, String, VipsOption...)
static VTarget	newToMemory(Arena arena)	Create a new memory-backed VipsTarget This target can be used with (for example) VImage.writeToTarget(VTarget, String, VipsOption...) After writing to this target, you can also retrieve the backing VBlob with getBlob()
