Reconstruction modes
You can choose one of the following reconstruction modes:
Rigid Maintains right angles in the pixel grid (as shown by the mesh) at the edges between frozen and unfrozen
areas, sometimes producing near-discontinuities at the edges. This restores the unfrozen areas so that they approx-
imate their original appearance. (To restore their original appearance, use Revert reconstruction mode.)
Stiff Acts like a weak magnetic field. At the edges between frozen and unfrozen areas, the unfrozen areas take on the
distortions of the frozen areas. As the distance from frozen areas increases, the distortions lessen.
Smooth Propagates the distortions in frozen areas throughout unfrozen areas, with smoothly continuous distor-
tions.
Loose Produces effects similar to Smooth, with even greater continuity between distortions in frozen and unfrozen
areas.
Revert Scales back distortions uniformly without any kind of smoothing.
Reconstruct tool modes
The Reconstruct tool has three modes that use the distortion at the point where you first clicked the tool (start point)
to reconstruct the area over which you use the tool. Every time you click, you set a new start point; so, if you want to
extend an effect from one start point, don’t release the mouse button until you finish using the Reconstruct tool.
Displace Reconstructs unfrozen areas to match the displacement at the start point for the reconstruction. You can
use Displace to move all or part of the preview image to a different location. If you click and gradually spiral out from
the start point, you displace or move a portion of the image to the area you brush over.
Amplitwist Reconstructs unfrozen areas to match the displacement, rotation, and overall scaling that exist at the
start point.
Affine Reconstructs unfrozen areas to match all distortions that exist at the start point, including displacement,
rotation, horizontal and vertical scaling, and skew.
Work with meshes
Using a mesh helps you see and keep track of distortions. You can choose the size and color of a mesh, and save the
mesh from one image and apply it to other images.
• To add a mesh, select Show Mesh in the View Options area of the dialog box, and choose a mesh size and mesh
color.
• To show a mesh, select Show Mesh. When Show Mesh is selected, you can show or hide the preview image. Select
Show Image in the View Options area of the dialog box to show the preview image; deselect Show Image to view
only the mesh.
• To save a distortion mesh, after distorting the preview image, click Save Mesh. Specify a name and location for the
mesh file, and click Save.
• To apply a distortion mesh, click Load Mesh, select the mesh file you want to apply, and click Open. If the image
and distortion mesh aren’t the same size, the mesh is scaled to fit the image.
Work with backdrops
You can choose to show only the active layer in the preview image, or you can show additional layers in the preview
image as a backdrop. Using the Mode options, you can position the backdrop in front of or behind the active layer
to keep track of your changes, or to line up a distortion with another distortion made in a different layer.
