Working with Reference Layers
Reference layers get their image content from an external source — either a pixel-
based layer in the current document or a separate file. They provide a low-resolution
representation of the original image that you can quickly manipulate in ways that
would otherwise require more time. Working with a reference layer allows you to
transform (resize, rotate, or slant) a layer onscreen by dragging its handles. You can
adjust various options. Transformations are immediately displayed in the document
window. When you finish applying transformations, you commit the reference layer
back to a standard layer. Corel Painter examines the source image to restore the
original resolution.
You cannot edit the image data in a reference layer. If you try to paint on or apply
effects to a reference layer, Corel Painter prompts you to commit it back to a
pixel-based layer.
You can create a reference layer by basing it on an existing layer or by placing an
image. For more information about placing images, see to “Placing Files” on page 19.
To create a reference layer
1 Select a layer.
2 Choose Effects menu > Orientation > Free Transform.
The layer’s icon on the Layers palette changes to an eight-handled square , and
an eight-handled box marks the boundary of the layer’s contents in the document
window.

To Do the following
Resize a reference layer in one direction Drag a side handle to resize the layer in one

two directions at once. If you want to
maintain the layer proportions, hold down
Shift as you drag. The pointer changes when
you position it over a corner handle .
