Controls
Presets
To select a preset, pick one from the Presets window.
Center
Center location of the kaleidoscoped image.
Z Dist
Scales the distance of the entire result in or out from the Center. Increase to zoom out, decrease to zoom in.
Rotate
Rotates the kaleidoscope's reflection pattern about the Center by this many counterclockwise degrees.
Stretch X & Y
Scales the horizontal or vertical size of the result.
Inside Shift Y
Shifts the image up by this amount before it is reflected. This causes the resulting pattern of images to radiate outward from the center.
Angle Repeats
The number of copies of the image to wrap around. This should be an even integer to avoid a seam where the first copy connects to the last.
Kaleido Amount
Adjusts the overall amount of distortion applied to the image. Set this to 0 to leave the image unchanged or to 1 for a normal kaleidoscope pattern.
Filter
If enabled, the image is resampled using pixel averaging. This removes aliasing and gives a higher quality result, although it may not be necessary if your image is smooth with no sharp edges or high frequencies.
Crop Input
These 4 parameters, Crop Top, Crop Bottom, Crop Left, and Crop Right, allow selecting a rectangular subsection of the image to be processed. If the Wrap parameters are set to "No" the exposed borders will be transparent. If the Wrap is "Tile" or "Reflect", the image is wrapped on the new cropped borders to fill the frame. This can make it easier to avoid artifacts due to distorting an image with bad edges.
Show Center
Enables/disables the on-screen control for adjusting the Center parameter.
