Blurkit Android
Blurkit-android is a library for applying real-time image transformations and blur-behind effects to views and bitmaps within Android applications. It functions as an image processing tool to transform visual content into blurred versions using optimized rendering methods.
The project focuses on high-performance background blur rendering, enabling the creation of layered layouts with adjustable blur radius. It achieves this through a combination of hardware-accelerated drawing, bitmap downsampling, and the use of a compute framework to parallelize calculations across the GPU and multi-core CPUs.
The library provides capabilities for view-hierarchy snapshotting and canvas-based layer compositing to maintain smooth frame rates during UI transitions and animations.
Features
- Blurred View Overlays - Renders a high-performance blurred version of background content as a stylized overlay for Android views.
- Android Hardware Acceleration - Utilizes Android native graphics APIs for hardware-accelerated rendering of blurred layers.
- Image Blur Filters - Provides dedicated image processing techniques to transform views and bitmaps into blurred versions.
- GPU-Accelerated Processing - Employs RenderScript to parallelize blur calculations across the GPU and multi-core CPUs for high performance.
- Android Blur Effect Libraries - Provides a comprehensive set of tools for applying real-time blur effects to Android views and bitmaps.
- Android Image Processing - Implements visual filters and blur effects specifically for images and bitmaps within the Android ecosystem.
- Real-Time Background Blurs - Implements high-performance real-time blur-behind layouts that mirror modern mobile visual styles.
- View Snapshotting - Captures the visual state of background view hierarchies as bitmaps to avoid expensive full-layout re-rendering.
- Real-Time Filter Modulation - Allows dynamic adjustment of blur intensity by varying the Gaussian filter kernel size during draw cycles.
- Canvas Compositing - Uses custom canvas compositing to blend blurred bitmap buffers with foreground content.
- Image Downsampling - Implements image downsampling during the blur pipeline to optimize memory usage and rendering speed.
- Layout Optimizations - Optimizes layout rendering to ensure smooth frame rates during blur-behind transitions and animations.
- Performance Optimizations - Optimizes image retrieval and drawing sequences to maintain smooth frame rates during blur rendering.
- UI Visual Effects - Creates a modern layered visual style by adding real-time blurring effects to Android interface elements.
