This is a really nice tool, Good job! Would be nice if we could zoom in/out, Also if we could choose the resolution, My App screenWidth and screenHeight don't match the tool resolution.
Great tool, I wish we can have something such as "TexUnpacker", Would be nice if we could detect sprites within a sprite sheet, and export data to the formats supported by the app, something like "Atlas Image Data Generator" app do but the interface there is buggy and not user very user friendly.
