5.12.1. Overview

This filter creates a kind of bubble whose size is that of the image or selection, as if the content was wrapped around a sphere.

5.12.3. Options

Figure 17.80. “Spherize” filter options

Presets, “Input Type”, Clipping, Blending Options, Preview, Merge filter, Split view

	Note
	These options are described in Section 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 Interpolation.

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.
