Usage

Basic usage

from pytomosaic import createMosaic

imgPath = "target.jpg"
sourceImages = "source_folder"
cropSize = 50  # Size of mosaic parts in px

# Generate mosaic with verbose progress
mosaic = createMosaic(imgPath, sourceImages, cropSize, verbose=True)
mosaic.show()

Reusing preloaded tiles for multiple images

from pytomosaic import createMosaic
from pytomosaic.tileManager import TileManager

# Preload tiles once
tiles = TileManager(cropSize=50, sourceImagesDir="source_folder", verbose=True)

# Generate multiple mosaics using the same tiles
mosaic1 = createMosaic("photo1.jpg", tiles)
mosaic2 = createMosaic("photo2.jpg", tiles)

Set verbose=False or leave empty to disable prints and progress bars.

Supported Image Extensions

VALID_EXTENSIONS = {
