AndreaMosaic

AndreaMosaic is software designed to generate photo mosaics from a collection of images. It uses advanced algorithms to combine many small images into a composition that reveals a main picture when viewed from a distance.

• Base image selection. The program lets you load a main image that serves as a guide for the mosaic. This image is analyzed to determine the distribution of colors and shapes needed to recreate it using images from your collection.
• Image library. AndreaMosaic works with a library of secondary images used as tiles to build the mosaic. These images can be imported in batches and organized into categories.
• Color matching. The software compares the colors of the secondary images with those of the base image, selecting the best match for each section of the mosaic. It includes options to prioritize hue, saturation, or brightness.
• Density control. It lets you define the number of secondary images used per row and column, which affects the level of detail in the final result.
• Real-time preview. It shows an approximate representation of the mosaic during setup, allowing you to adjust parameters before generating the final version.
• Layout optimization. It includes algorithms that distribute the secondary images evenly, avoiding frequent repetition of the same image in nearby areas.
• High-resolution export. It generates output files in common formats such as JPEG, PNG, or TIFF, with the option to specify exact dimensions and compression quality.
• Grayscale mode. It offers the option to convert the mosaic to black and white, preserving the tonal range by using secondary images of different intensities.
• Tile size adjustment. It lets you configure the dimensions of the secondary images in the mosaic, either uniformly or with controlled variations for artistic effects.
• Image filtering. It provides tools to exclude secondary images that do not meet certain criteria for size, aspect ratio, or content, improving the visual consistency of the result.
• Color profile support. It works with different color spaces, including sRGB and Adobe RGB, to ensure color fidelity on specific output devices.
• Batch processing. It can generate multiple mosaics at once by applying the same settings to different base images.

AndreaMosaic was developed by Andrea Denzler and first released in 2005. Over the years it has received updates that improved its algorithms and expanded its rendering capabilities. The latest stable version offers faster processing and makes better use of modern hardware.
