Image Editor Sprite

Purpose and use cases: This tool consolidates multiple input images into a single texture atlas, reducing runtime texture swaps and improving rendering efficiency. It targets game developers, UI teams, and asset pipelines that require scalable sprite management. The atlas provides a PNG sprite_sheet and a per-frame map for coordinates, widths, and heights, enabling straightforward integration into CSS or engine-driven animations.
Conceptual workflow: users supply a collection of images, configure a global padding between frames, and optionally trim transparent borders. A deterministic rectangle-packing algorithm places frames within atlas bounds and outputs a coordinate map for each frame.
Value and use cases: predictable layouts, batch processing, and automation-friendly assets suit icon sets, animated sequences, and responsive sprites across platforms. The tool emphasizes reproducibility and ease of integration into build pipelines.
Core features include multiple inputs, padding control, trimming options, atlas size constraints, and outputs in PNG plus JSON/CSS formats. It does not edit images, optimize colors, bake animations, or compress textures.
