**Design image pipelines visually. Automate with Python.**

Node-based GPU compositor with real-time preview and headless batch processing.

Core is [PyImageCUDA](https://github.com/offerrall/pyimagecuda), my custom CUDA library with native kernels for all operations.

Dependencies only for UI (PySide6), I/O (PyVips), and preview (PyOpenGL), no CUDA Toolkit required (just NVIDIA drivers).

## Key Features

### Visual Node Editor
- **40+ GPU-accelerated nodes**: Generators, effects, filters, transforms, blend modes (see full list below)
- **Real-time preview**: CUDA-OpenGL interop for instant visual feedback on every change
- **Global variables**: Link any parameter across multiple nodes for template reuse
- **Flexible controls**: Numeric inputs with optional sliders for precise adjustments
- **Intuitive workflow**: Right-click to add nodes, drag to connect, see results instantly

### Headless Automation
- **Simple Python API**: Load `.pics` projects and modify parameters programmatically
- **Batch processing**: Generate thousands of variations in seconds
- **Type-safe validation**: All parameters validated (colors, sizes, text, ranges, etc.)

```python
from pyimagecuda_studio import LoadProject, run, set_node_parameter

with LoadProject("sign.pics"):
    for i in range(1, 11):
        set_node_parameter("Text", "text", f"Test {i}")
        run(f"output_{i:02d}.png")
```

### Performance
- **10-350x faster**: than CPU alternatives for complex operations, see [PyImageCUDA benchmarks](https://offerrall.github.io/pyimagecuda/benchmarks/)
- **5-15ms rendering** — Typical 1080p pipelines (RTX 3070, varies by GPU)
- **Memory efficient**: GPU buffers created on-demand and reused intelligently

---

## Installation

### Requirements
- **Python 3.10+**
- **NVIDIA GPU** (GTX 900 series or newer)

### Install via pip
```bash
pip install pyimagecuda-studio
```

### Launch GUI
```bash
pyimagecuda-studio
# or shorter alias:
pics
```

- **Scale** — Percentage-based scaling
- **Flip** — Horizontal/vertical/both
- **Rotate** — Arbitrary angles with optional expand
- **Crop** — Extract rectangular region

### Merge (2 nodes)
- **Blend** — Composite two images with Photoshop-style blend modes
  - **Modes:** Normal, Multiply, Screen, Add, Overlay, Soft Light, Hard Light
  - **Positioning:** 9 anchor points (top-left, center, bottom-right, etc.) + pixel offset
  - **Control:** Opacity slider (0.0-1.0)
- **Mask** — Use image brightness or alpha as transparency mask
  - **Modes:** Luminance (brightness) or Alpha channel

### Logic (2 nodes)
- **Random Out** — Randomly select between inputs
- **Conditional** — Python-based routing logic

### Utility (1 node)
- **Split** — Duplicate to 2 outputs

## Headless Mode

Design templates in the GUI, automate generation with Python.

### Basic Example
```python
from pyimagecuda_studio import LoadProject, set_node_parameter, run

with LoadProject("template.pics"):
    set_node_parameter("Text", "text", "Hello World")
    run("output.png")
```

### Batch Processing
```python
from pyimagecuda_studio import LoadProject, set_node_parameter, run

with LoadProject("certificate.pics"):
    for name in ["Alice", "Bob", "Charlie"]:
        set_node_parameter("Text", "text", f"Certificate for {name}")
        run(f"certs/{name}.png")
```

### Global Variables

Control multiple parameters at once:
```python
from pyimagecuda_studio import LoadProject, set_variable, run

with LoadProject("banner.pics"):
    set_variable("primary_color", (0.2, 0.4, 0.8, 1.0))
    set_variable("title", "Summer Sale")
    run("output.png")
```

### Real-World: CSV Data
```python
import csv
from pyimagecuda_studio import LoadProject, set_variable, run

with LoadProject("product_card.pics"):
    with open('products.csv') as f:
        for row in csv.DictReader(f):
            set_variable("product_name", row['name'])
            set_variable("price", f"${row['price']}")
            set_node_parameter("Image", "path", row['image_path'])
            run(f"cards/{row['id']}.png")
```

### API Functions
```python
# Load project (context manager handles cleanup)
with LoadProject(filepath, trust_code=False):
    
    # Modify nodes directly
    set_node_parameter(node_name, param_name, value)
    
    # Modify global variables
    set_variable(name, value)
    
    # Generate output
    run(output_path, quality=None)
    
    # Query project
    get_nodes()           # -> list[str]
    get_variables()       # -> list[str]
    get_node_parameters(node_name)  # -> dict
```

### Security Note

Projects with **Dynamic Text** or **Conditional** nodes execute Python code. Set `trust_code=True` only for projects you trust:
```python
with LoadProject("untrusted.pics", trust_code=True):  # ⚠️ Only if you trust the source
    run("output.png")
```
