Class
VipsConnection
Description [src]
abstract class Vips.Connection : Vips.Object {
parent_object: VipsObject
}An abstract base class representing a source or sink of bytes.
It can be connected to a network socket, for example, or perhaps
a Node.js stream, or to an area of memory. This allows it to support
operations like JPEG loading, see for example vips_jpegload_source().
Subclass to add other input sources. Use VipsSourceCustom and
VipsTargetCustom to make a source or target with action signals.
These classes provide action signals such as:
VipsSourceCustom::readfor reading data from a custom source.VipsSourceCustom::seekfor seeking within a data stream.VipsTargetCustom::writefor writing data to a custom target.

Vips.Object::postbuild
The ::postbuild signal is emitted once just after successful object construction. Return non-zero to cause object construction to fail.

The ::postclose signal is emitted once after object close. The object pointer is still valid, but nothing else.
