PhotoMosaic-Artifact

What PhotoMosaic-Artifact is

PhotoMosaic-Artifact is a free, open-source desktop tool for creating photographic mosaic images from a custom tile library. It supports Linux, macOS and Windows, and offers both a graphical interface and the `photomosaic-core` command-line tool. The command accepts settings for the mosaic’s rows and columns, output scale, source material folder and video sampling interval. Other listed controls include color enhancement, thumbnail filtering, tolerance and a random seed. Video files can be included as source material, with their sampling interval set in milliseconds. Source images whose aspect ratio differs from the mosaic thumbnail are cropped to match its proportions. The output image dimensions must divide evenly by the chosen row and column counts. The project describes its algorithm as a Python implementation based on eflorit’s mosaic-generator. Its listed requirements are Pillow 6.1.0 or later, numpy 1.17.0 or later, and opencv-python 4.1.0.25 or later. It exports JPEG images. The repository uses the MIT License, which allows use, copying, modification, distribution, sublicensing and sale under its terms. The releases page lists a Ver1.2 release with eight assets.

Who it suits

PhotoMosaic-Artifact suits people who want to build photo mosaics from their own image collections, with either a GUI or command-line settings. It can also suit users who want to include video material or adapt the open-source Python project.

Limits

The output image dimensions must be divisible by the selected row and column counts. Material images with a different aspect ratio from the mosaic thumbnail are cropped to fit.

Getting started

1. Open the project website on GitHub.
2. Choose the GUI or command-line tool for your workflow.
3. Install Pillow 6.1.0 or later, numpy 1.17.0 or later, and opencv-python 4.1.0.25 or later.
4. Choose your material folder and set the output rows, columns and scale.
5. If using video material, set its sampling interval in milliseconds.
6. Create a JPEG mosaic with output dimensions divisible by the selected row and column counts.

Verdict

Choose PhotoMosaic-Artifact if you want a free desktop mosaic maker with custom source material, video support and adjustable command-line settings. Look elsewhere if you need output dimensions that do not divide evenly by your chosen grid or need mismatched source images preserved without cropping.
