pyimagecuda 0.0.4

GPU-accelerated image processing library for Python

PyImageCUDA 0.0.4

GPU-accelerated image compositing for Python.

PyImageCUDA focuses on creative image generation rather than computer vision. Expect GPU-accelerated effects for design workflows—blending modes, shadows, gradients, filters... not edge detection or object recognition.

Quick Example

from pyimagecuda import Image, Fill, Effect, Blend, Transform, save

with Image(1024, 1024) as bg:
    Fill.color(bg, (0, 1, 0.8, 1))
    with Image(512, 512) as card:
        Fill.gradient(card, (1, 0, 0, 1), (0, 0, 1, 1), 'radial')
        Effect.rounded_corners(card, 50)

        with Effect.stroke(card, 10, (1, 1, 1, 1)) as stroked:
            with Effect.drop_shadow(stroked, blur=50, color=(0, 0, 0, 1)) as shadowed:
                with Transform.rotate(shadowed, 45) as rotated:
                    Blend.normal(bg, rotated, anchor='center')

    save(bg, 'output.png')

Key Features

• ✅ Zero Dependencies: No CUDA Toolkit, Visual Studio, or complex compilers needed. Is Plug & Play.
• ✅ Ultra-lightweight: library weighs <0.5 MB.
• ✅ Studio Quality: 32-bit floating-point precision (float32) to prevent color banding.
• ✅ Advanced Memory Control: Reuse GPU buffers across operations and resize without reallocation—critical for video processing and batch workflows.
• ✅ API Simplicity: Intuitive, Pythonic API designed for ease of use.

Use Cases

• Generative Art: Create thousands of unique variations in seconds.
• Motion Graphics: Process video frames or generate effects in real-time.
• Image Compositing: Complex multi-layer designs with GPU-accelerated effects.
• Game Development: Procedural UI assets, icons, and sprite generation.
• Marketing Automation: Mass-produce personalized graphics from templates.
• Data Augmentation: High-speed batch transformations for ML datasets.

Installation

pip install pyimagecuda

Note: Automatically installs pyvips binary dependencies for robust image format support (JPG, PNG, WEBP, HEIC).

Documentation

⚠️ Alpha Release: Many more features are planned and under development. If you have specific needs or bug reports, please open an issue on GitHub.
