Pica-gpu is a high-quality, GPU-accelerated image resizer designed to significantly enhance the performance of image processing tasks. Inspired by Pica, pica-gpu utilizes WebGL technology to offload filtering and convolution operations to the GPU, which leads to a substantial performance boost of 2-10x compared to traditional CPU-based image resizing. This performance improvement is particularly evident when handling large images, as the GPU efficiently manages resource-intensive tasks, reducing CPU load and memory consumption.

Key Features

• GPU-accelerated image scaling: Efficiently offloads per-pixel image processing to the GPU using WebGL, enabling faster image resizing.
• High-quality filters: Offers support for advanced filtering algorithms, including mks2013, ensuring exceptional image quality with effective anti-moiré and sharpening effects.
• Improved performance: Enjoy a significant speed increase—up to 10 times faster—compared to the CPU-based Pica, especially beneficial for larger images.
• Reduced resource usage: Minimizes CPU and memory overhead by performing image operations directly on the GPU, avoiding the creation of extra buffers.
• Simplified implementation: Unlike Pica, pica-gpu does not require complex setups such as web workers; it operates seamlessly with any environment that supports WebGL.
• User-friendly API: Designed as a drop-in replacement for Pica, featuring a similar API surface that simplifies the integration process.

Usage Example

To leverage pica-gpu in a project, follow this straightforward usage pattern:

import { resize } from 'pica-gpu';

resize(source, {
    filter,
    targetWidth,
    targetHeight,
    // additional options...
});

Pica-gpu provides efficient and high-quality image resizing capabilities suitable for demanding applications, enhancing both performance and user experience. Whether for web apps, mobile applications, or any project requiring image manipulation, pica-gpu stands out as a fast and reliable tool.
