S_TileScramble Breaks the image into rectangular tiles and shifts the image within each tile to create an effect like a wall of small randomly oriented mirrors reflecting the source image. The amount and direction of shifting are controllable. In the Sapphire Stylize effects submenu. Inputs: Source:  The input clip to be warped. Mask:  Optional.   If provided, the amplitude of warping is scaled by the values of this input clip. Gray values internally scale the warping amplitude rather than simply cross-fading between the effect and the original source to allow more continuous results at the mask edges and more detailed control over the warping amounts. This input can be affected using the Blur Mask, Invert Mask, or Mask Use parameters.

Parameters:

Amount:   Default: 0.1,  Range: any.
How much scrambling to apply to each tile. Zero gives the original image.

Amount Rel X:   Default: 1,  Range: 0 or greater.
Relative scramble amount in X. Set to zero to get only vertical scrambling.

Amount Rel Y:   Default: 1,  Range: 0 or greater.
Relative scramble amount in Y. Set to zero to get only horizontal scrambling.

Tiles:   Default: 10,  Range: 1 or greater.
How many tiles across the image. Increase for many tiny tiles; decrease for a few large ones.

Tile Rel Width:   Default: 1,  Range: 0.01 or greater.
Scales the height of each tile.

Tile Rel Height:   Default: 1,  Range: 0.01 or greater.
Scales the width of each tile.

Tile Shift:   X & Y,   Default: [0 0],  Range: any.
shifts the edges of the tiles in X and Y. This doesn't shift the contents of the tiles, just the boundaries. Animate for an interesting effect. This parameter can be adjusted using the Tile Shift Widget.

Rotate Warp Dir:   Default: 0,  Range: any.
Rotates the warping direction by this many degrees. Animate to rotate the tiles around for an interesting effect.

Z Dist:   Default: 1,  Range: 0.01 or greater.
Scales the distance of the image in each tile in or out from its center. Increase to zoom out, decrease to zoom in.

Seed:   Default: 0.123,  Range: 0 or greater.
Used to initialize the random number generator. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.

Wrap:   Popup menu,  Default: No.
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: off.
If enabled, the image is filtered when it is resampled smaller. This gives a better quality result when Z Dist is greater than 1. Has no effect when Z Dist is 1 or less.

Blur Mask:   Default: 0,  Range: 0 or greater.
Blurs the Mask input by this amount before using. This can provide a smoother transition between the masked and unmasked areas. It has no effect unless the Mask input is provided.

Invert Mask:   Check-box,  Default: off.
If on, inverts the mask input so the effect is applied to areas where the Mask is black instead of white. This has no effect unless the Mask input is provided.

Mask Use:   Popup menu,  Default: Luma.
Determines how the Mask input channels are used to make a monochrome mask.

Luma:  the luminance of the RGB channels is used.

Alpha:  only the Alpha channel is used.

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