Sprite Sheet Composer

Sprite Sheet Composer is a desktop 2D illustration and animation sheet layout
studio for combining individual PNG and WebP character frames into organized
image sheets, previewing flipbook motion, and exporting frame coordinate files.
An independent Linux desktop alternative to traditional 2D animation sheet
editors for arranging frame grids, checking motion timing, and generating
coordinate metadata for creative projects.

Key Features:
- Automatic Frame Sheet Layout: Import PNG and WebP artwork frames, crop
transparent outer margins cleanly, add configurable inner spacing and border
padding for clean rendering, and arrange frames into power-of-two or compact
rectangular image sheets.
- Flipbook Animation Player: Preview frame sequences from 1 to 60 FPS with
Loop, Ping-Pong, and Single-Play modes, onion-skin overlay, pixel-art zoom,
and an interactive frame boundary viewer.
- Multi-Format Coordinate Exporter: Save composed PNG and WebP sprite sheets
together with JSON Hash, JSON Array, XML, CSS Sprites, and CSV coordinate
tables with area utilization statistics.
