Detailed Description

A generic source object. These supply a stream of bytes that loaders can use to fetch image files, see VImage::new_from_source().

Methods let you can connect a source up to memory, a file or a file descriptor. Use vips::VSourceCustom to implement custom sources using GObject signals.

Constructor & Destructor Documentation

VSource()

VSource::VSource ( VipsSource *  input, VSteal  steal = STEAL  )

inlineexplicit

Wrap a VSource around an underlying VipsSource object.
