Graphics

LogNGraph provides a simple interface for drawing primitives using Pygame.

Creating a Window

from logngraph.graph import Window

# Basic window
window = Window(title="My Window", width=800, height=600)

# Advanced window
window = Window(
    title="My Window",
    width=800,
    height=600,
    resizable=True
)

Drawing Primitives

Shapes

# Rectangle
window.rect((x, y), (width, height), color="#ff0000")

# Circle
window.circle((center_x, center_y), radius, color="#00ff00")

# Line
window.line((start_x, start_y), (end_x, end_y), color="#0000ff", width=15)

# Polygon
window.polygon((x1, y1), (x2, y2), (x3, y3), color="#ffff00")

Text

window.write(
    (x, y),
    text="Hello World",
    color="#ffffff",
    bg_color=None,  # Transparent background
    antialias=True,
    size=24,
    font="Arial"
)

Transformations

# Translation
window.translate(dx, dy)  # Set origin

# Rotation
window.rotate(angle)      # Set rotation around current origin

Window Management

# Update display
window.update()

# Handle events
window.handle_events()

# Screenshot
window.screenshot("screenshot.png")

# Get window size
width, height = window.get_size()

# Set window title
window.set_title("New Title")

Color System

LogNGraph supports multiple color formats:

Hex strings: “#ff0000”, “#f00”
Color names: “red”, “blue”, “green”

Basically what PyGame supports.
