Mosaic Magnifique is an open source photomosaic generator with a graphical interface, available as a pre-built Windows app. Its grid preview overlays cell boundaries on the main image, and grid editing lets users add or reduce detail in selected areas or exclude them. Image matching offers RGB Euclidean, CIE76, and CIEDE2000 formulas. Users can create custom cell shapes from an image and adjust spacing, offsets, flipping, and alternate spacing. Repeat controls set a range for finding reused images and add a value to difference calculations for repeats in that range. Colour Visualisation compares colours in the image library with the main image and identifies colours that could improve the library for that image. Users can adjust the photomosaic background colour, including its alpha value. The app can use CUDA on a CUDA-capable GPU; its maker says this makes CIEDE2000 results much faster. The releases page provides a datapack with an Image Library and sample main images. The current build is Windows-only, and CUDA support is currently limited to Windows.
Who it is for
Mosaic Magnifique suits Windows users who want a graphical tool for building photomosaics and adjusting image matching, cell shapes, and detail. Its controls also suit users managing repeated image tiles or improving an image library for a particular main image.
