Class
VipsObject
Description
abstract class Vips.Object : GObject.Object {
parent_instance: GObject,
constructed: gboolean,
static_object: gboolean,
argument_table: VipsArgumentTable*,
nickname: char*,
description: char*,
preclose: gboolean,
close: gboolean,
postclose: gboolean,
local_memory: size_t
}Constructors
vips_object_new
G_object_new() the object, set any arguments with set, call
vips_object_build() and return the complete object.
vips_object_new_from_string
Functions
vips_object_get_property
vips_object_map
Call a function for all alive objects.
Stop when fn returns non-NULL and return that value.
vips_object_print_all
vips_object_print_summary_class
vips_object_sanity_all
vips_object_set_property
vips_object_summary_class
Generate a human-readable summary for a class.
Instance methods
vips_object_argument_needsstring
vips_object_build
vips_object_dump
Dump everything that vips knows about an object to a string.
vips_object_get_args
Get all %GParamSpec names and VipsArgumentFlags for an object.
vips_object_get_argument
Look up the three things you need to work with a vips argument.
vips_object_get_argument_to_string
vips_object_get_description
Fetch the object description. Useful for language bindings.
vips_object_local_array
Make an array of NULL VipsObject pointers. When parent closes, every
non-NULL pointer in the array will be unreffed and the array will be
freed. Handy for creating a set of temporary images for a function.
vips_object_local_cb
vips_object_preclose
vips_object_print_dump
vips_object_print_name
vips_object_print_summary
vips_object_rewind
vips_object_sanity
vips_object_set
Set a list of vips object arguments. For example:
vips_object_set_argument_from_string
vips_object_set_from_string
Set object arguments from a string. The string can be something like “a=12”, or “a = 12, b = 13”, or “fred”. The string can optionally be enclosed in brackets.
vips_object_set_required
vips_object_set_static
vips_object_set_valist
See vips_object_set().
vips_object_summary
Generate a human-readable summary for an object.
vips_object_to_string
The inverse of vips_object_new_from_string(): turn object into eg. “VipsInterpolateSnohalo1(blur=.333333)”.
vips_object_unref_outputs
Unref all assigned output objects. Useful for language bindings.
Properties

Vips.Object:nickname
Signals
Vips.Object::close
The ::close signal is emitted once during object close. The object is dying and may not work.
Vips.Object::postbuild
The ::postbuild signal is emitted once just after successful object construction. Return non-zero to cause object construction to fail.
Vips.Object::postclose
The ::postclose signal is emitted once after object close. The object pointer is still valid, but nothing else.
Vips.Object::preclose
The ::preclose signal is emitted once just before object close starts. The oject is still alive.
Signals inherited from GObject (1)
GObject.Object::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
