This is a custom Android view designed for rendering high-resolution images using subsampling and tiling to prevent memory overflows. It serves as an interactive image component that supports pinch-to-zoom, panning, and double-tap animations.
The project is distinguished by its rendering engine, which loads low-resolution previews and high-resolution tiles to enable the efficient navigation of massive image files. It includes a coordinate mapper that converts screen touch points into raw image pixel coordinates and vice versa during scaling and panning.
The view provides a broad set of capabilities including image gesture handling, customizable zoom constraints, and image orientation rotation. It supports the integration of custom overlays and graphics that maintain their relative position and scale during interaction. Additionally, it offers tools for monitoring image loading states and displaying rendering debug information.
