PhotoDemon’s Spherize tool allows you to take a rectangular image and wrap it around a virtual sphere. Several options are available: the angle (or tilt) of the sphere, horizontal or vertical offsets (to change where the wrapping begins in either direction), and just for fun, a “matching light rays” option for the blank space around the sphere.
Like other distortion tools in the program, five options are provided for dealing with off-canvas pixels (clamp, erase, ignore, reflect, wrap). A dedicated Quality option uses bilinear interpolation to further improve the quality of the final image.
Finally, like all PhotoDemon tools, a dedicated command bar allows you to save and load custom presets, randomize parameters, and reset to default values. Last-used settings are automatically saved and restored, and all changes provide a real-time preview (no click or mouse button release required).
