Using Image Effects290
Use the Image Warp effect to warp your image.
Your computer must have a math
coprocessor to use the Image Warp
effect.
To warp an image:
1 Select a layer or area of the canvas.
If you want to apply the effect to
the entire image, make sure there
are no selections.
2 Choose Effects menu > Surface
Control > Image Warp.
3 In the Image Warp dialog box,
choose one of the following warp
methods:
• Linear pulls the selected area as
if you were pulling from the top
of a cone.
• Cubic pulls a flat surface out-
wards.
• Sphere pulls a surface as if it
were a lens.
4 Adjust the Size slider.
This slider controls the size of the
area affected by dragging the
cursor. The higher the number, the
smaller the affected area.
5 In the preview window, drag to
distort the image.
A circle displays as you drag,
indicating the area affected.
6 When you are satisfied with the
settings, click OK to apply the
effect.
Quick Warp
The Quick Warp command lets you
create some basic distortions, like
stretch or bulge. These distortions are
useful for preparing images for
reflection maps when applying surface
texture. For more information about
surface texture and reflection maps,
refer to “Working with Reflection
Maps” on page 284.
There are five types of distortions you
can create using Quick Warp:
• Sphere warps the image
spherically, like a reflection on a
polished silver ball. Use the Power
and Angle Factor sliders to
intensify and twist the effect.

• Bump warps the center of the
image toward you, making it
appear convex. Use the Angle
Factor slider to twist the effect.
