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

Mode
  Radial

    Maps the image in a sphere around the center. This is the default. See the example above.

  Horizontal

    Stretches the image horizontally around an imaginary sphere.

  Vertical

    Stretches the image vertically around an imaginary sphere.

Angle of view

  Camera angle of view (0 - 180°)

Curvature

  The Spherical cap angle, as a fraction of the complement angle of view. The result is less domed as the curvature decreases from 1 to 0.

Amount

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

Resampling method

  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.
