2.6 Manipulating Layers
As already discussed, layers are the most important image components
for image manipulation. They are the basic raw materials you want to
work with and combine. In most every GIMP project, layers need to be
moved, resized, positioned, transformed, cut, pasted, and so on.
These types of layer operations are discussed in this section.
2.6.1 Positioning Layers
One of the most basic layer operations is positioning. Compositing
from a set of raw image materials requires that the various
components, each on a separate layer, be appropriately positioned.
This section describes several techniques for layer positioning.
