Mosaic Shapes. The user selects a number of colours plus a background colour and opacity. The selected colours are ordered by local brightness, i.e. the brightness of each shape that the software selcts, and the base photo is analysed into an equivalent number of segments, each forming an equal proportion of the whole base image. Shape colours are then chosen by their equivalent position in the brightness order. As ever, it is to see the effects.
Shapes may be stars, polygons, or text. The polygons can be rectangles in which case the software aligns them horizontally to give a tile effect.
