  | Poznámka
  These options are described in 2 – „Common Features“.

Mode

  - Radial is the default mode. See example above.

  - Horizontal: as if image was mapped on a vertical cylinder.

  - Vertical: as if image was mapped on a horizontal cylinder.

Angle of view

  Camera angle of view (0 - 180°)

Curvature

  Spherical cap angle, as a fraction of the co-angle (complement angle) of view. Result is less domed as curvature decreases (100% - 0).

Amount

  Interesting for negative values, which result in a hollow instead of a bump (from 1.000 to -1.000).

Resampling methods

  These interpolation methods are described in Cubic (sometimes called „Bicubic“): The color of each pixel is computed as the average color of the eight closest pixels in the original image. This usually gives the best result, but it naturally takes more time..

#### 5.12.4. Using Spherize filter

Drawing a selection before applying filter allows you to create another shape, such as a sphere: select Ellipse tool with the Fixed option checked; draw a circle; apply Spherize filter with the Use the selection as input selected. Invert selection and fill it with wanted background.
