Spherical Distortion
Spherical Distortion
The Spherize filter can distort an image to simulate a reflection on a curved surface.
To Apply the Spherize Filter:
- Select a paint object. Make a selection to limit the effect to an area. If you don’t make a selection, the filter affects the entire image.
- Choose Image | Filter | Other | Spherize or use the Filter menu in the Properties bar.
- Adjust the settings in the dialog box and click OK to apply the filter.
| Original paint object |
| Spherize: Amount = 5 |
| Vignette option selected |
Amount | The extent of the distortion. Type a number from 1 to 10 or drag the slider. A higher number simulates a stronger curve. |
Projection Mode | The shape of the distortion. Select Spherical/Ellipsoid to simulate reflection on a spherical surface like a globe. Select Cylindrical to simulate reflection on a cylinder, such as a can. Select Horizontal to make cylindrical distortion horizontal. Select Vertical to make cylindrical distortion vertical. Select Hyperboloid to simulate reflection on a concave hyperboloid surface. |
Vignette | Isolates the shape of a spherical distortion from the rest of the image. If the image has a visibility mask, the areas of the image that fall outside of the distorted area will be transparent. If the image does not have a visibility mask, the areas are filled with the current background color. Use this option when Spherical/Ellipsoid is selected. |
No Anti-Alias | Turns off smoothing of edges in the image. Deselect this option for a smoother effect. |
Preview | Displays the current effect before you apply the filter. |
