GEGL Glossary
-------------
[[connection]]
connection::
A link/pipe routing image flow between operations within the graph
goes from an output xref:pad[pad] to an input xref:pad[pad], in
graph glossary this might also be referred to as an edge.
[[DAG]]
DAG::
Directed Acyclic Graph, see xref:graph[graph].
[[graph]]
graph::
A composition of xref:node[nodes], the graph is a xref:DAG[DAG].
[[node]]
node::
The nodes are connected in the xref:graph[graph]. A node has an
associated operation or can be constructed graph.
[[operation]]
operation::
The processing primitive of GEGL, is where the actual image
processing takes place. Operations are plug-ins and provide the
actual functionality of GEGL.
[[pad]]
pad::
The part of a xref:node[node] that exchanges image content. The
place where image "pipes" are used to connect the various operations
in the composition.
[[input_pad]]
input pad::
consumes image data, might also be seen as an image parameter to the
operation.
[[output_pad]]
output pad::
a place where data can be requested, multiple input pads can reference
the same output xref:pad[pad].
[[sampler]]
sampler::
A resampling strategy used for transformations and warps.
[[property]]
property::
Properties control the behaviour of operations. Through the use of
GParamSpecs properties they are self documenting via introspection.
