S_FlysEyeCircles Breaks the image into circle shaped tiles and transforms the image within each shape, to create a fly's eye view effect. The Overlap options allow the circles to be combined in different ways where they overlap. The 'Inside' parameters transform the Source image before it is tiled into the pattern, and the 'Tile' parameters transform the entire fly's eye pattern. In the Sapphire Stylize effects submenu. Inputs: Source:  The clip to be processed.

Parameters:

Tile Frequency:   Default: 12,  Range: 0.1 or greater.
The frequency of the tile pattern, increase for more smaller tiles. This parameter can be adjusted using the Tile Freq Widget.

Tile Rel Height:   Default: 1,  Range: 0.01 or greater.
The relative height of the tile shapes, increase for taller tiles.

Tile Shift:   X & Y,   Default: [0 0],  Range: any.
Translates the tile pattern. This parameter can be adjusted using the Tile Shift Widget.

Circle Overlap:   Popup menu,  Default: Ave.
Determines the method used to combine the overlapping regions of the circles.

Ave:  uses a weighted average across the overlapping region for a smooth transition.

Screen:  uses a screen operation.

Max:  uses the lighter.

Min:  uses the darker.

Mult:  uses a multiply operation.

Circle Radius:   Default: 1,  Range: 0 to 1.
The radius of the circles relative to each other. If this is less than 1.0 you will get empty spaces between the circles. The color of these empty spaces will be either transparent, black, or white depending on the combine mode.

Edge Softness:   Default: 0,  Range: 0 to 1.
The softness of the edges of the circles. If this is increased, it may also be necessary to lower the Circle Radius to avoid rectangular artifacts where the soft edges overlap.

Inside Zdist:   Default: 2,  Range: 0 or greater.
Determines the zoom factor of the image inside each tile. Values greater than 1 zoom out, values less than 1 zoom in. If this is 1, Inside Rotate is 0, and Overall Zdist is 1, the result should be the same as the input image.

Inside Rotate:   Default: 0,  Range: any.
The rotation angle of the image inside each tile, in degrees.

Overall Zdist:   Default: 1,  Range: any.
Creates an overall zooming effect by making each tile look toward or away from the image center. Decrease to zoom in, increase to zoom out. When 0 all tiles should contain identical images.

Wrap:   Popup menu,  Default: Reflect.
Determines the method for accessing outside the borders of the source image.

No:  gives black beyond the borders.

Tile:  repeats a copy of the image.

Reflect:  repeats a mirrored copy. Edges are often less visible with this method.

Filter:   Check-box,  Default: on.
If enabled, the Source image is resampled using pixel averaging. This removes aliasing and gives a higher quality result especially when Inside Zdist is large. It may not be necessary if your input image is smooth or Inside Zdist is small.

Crop Input Parameters:   Default: 0,  Range: 0 or greater.
These 4 parameters, Crop Top, Crop Bottom, Crop Left, and Crop Right, allow selecting a rectangular subsection of the input 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 source 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 Tile Freq: Check-box, Default: off.
Turns on or off the screen user interface for adjusting the Tile Frequency parameter.

Show Tile Shift: Check-box, Default: off.
Turns on or off the screen user interface for adjusting the Tile Shift parameter.
