Tessera v1.0.14

Tessera is a standalone Windows app for preparing pixel art and icons.
It began as a way to correct uneven grids and inconsistent pixel sizes in AI-generated pixel art.

Change size and colors independently or together, align grids, reduce cells to single pixels and keep result histories. Create multi-size ICO files, or remove a solid background in its own workspace and save a full-size transparent PNG. Choose any library source or saved result from the From editor thumbnail panel. Background removal works globally or from connected image edges, with adjustable tolerance.

Convert supported Aseprite animations in batches to PNG sprite sheets with JSON frame timings. All processing runs locally.

What's new:

• Convert multilayer RGBA Aseprite animations: visible image layers are composited in order, hidden layers and groups stay hidden, and linked cels resolve within their own layer.
• Preserve color when compositing translucent pixels. Visible layers require Normal blending, full layer/cel opacity and zero cel z-index; unsupported modes still report an error.
• Use the shared Tessera.WpfStyles theme and bundled fonts throughout the desktop interface.
• Restore checkerboard, dark and light preview backgrounds behind transparent images.

Users of v1.0.11 or later can install this release through the app's update button. The image library stays in place.

Updating from v1.0.10 or earlier: download this release manually once to enable future in-app updates.

The CLI includes resize, colors, aseprite, align, reduce-grid, ico and remove-background commands for scripted workflows. Use reduce-grid (also available as compact-grid) to turn uniform aligned cells into individual pixels.

Download Tessera.exe or Tessera-win-x64.zip for the desktop app, or Tessera-cli-win-x64.zip for the CLI. No .NET installation is required. SHA256SUMS.txt contains the download checksums.

Previously named Pixelizator. The library is now stored at %LOCALAPPDATA%\Tessera\Library. On first launch, the old Pixelizator library is copied into it and retained as a backup. The application interface currently uses Russian labels.
