Box Fitting is a program originally developed by the genius mind of programmer / artist Jared Tarbell ported to Adobe Photoshop. The algorithm works by creating a single box and enlarging it until it either reaches the maximum size allowed or reaches the edge of another box. Ultimately, the canvas is filled with as many boxes as possible turning the image into a beautiful mosaic of randomly-sized squares.


Box Fitting creates a unique effect not possible without the use of an automated plugin. Moreover, Box Fitting yields spectacular results when used in high resolution.


Box Fitting provides flexible control over how many boxes to create, the maximum size allowed and a random seed generator. It allows the user to sample color from the image or assign a custom color with a variation threshold.


Box Fitting also features a preview and render multiplier for high resolution imaging.


Boxes: Defines the maximum number of boxes allowed. Obviously, the more boxes there are, the longer the computation. Make sure to check the preview window at 100% to ensure you have enough boxes. Keep in mind that this number will be the attempted number of boxes drawn but many are discarded if they fall outside legal boundaries.


Max Size: Defines the maximum size (in percent) allowable for each box. Each new box will be assigned a random size up to the maximum size. The preview window will display a minimum size if the zoom level is too low so it is recommended to zoom into 100% to see a true maximum size.


Seed: Changes the random generator seed.

Sample from image: Defines the box color based on image color. When deselected, the box color will be assigned a custom color with variation.

Col Var: Defines the maximum color variation when sampling from image is deselected.


Box Color: Defines the box color when sampling from image is deselected.

Line Color: Defines the box outline color.

Preview / Render Multipliers: Specifies iteration multipliers for high resolution renders.
