🔍 Code Extractor

Generates a PNG image file containing a sample algebra math problem with workspace lines for solving.

Purpose

Creates a demonstration image file (demo_math.png) showing a formatted algebra problem '2x + 7 = 23' with title, instructions, and workspace lines. Useful for testing image processing pipelines, OCR systems, educational content generation, or demonstrating document analysis capabilities.

Source Code

def create_math_problem():
    """Create a sample math problem"""
    img = Image.new('RGB', (800, 600), color='white')
    draw = ImageDraw.Draw(img)

    draw.text((50, 140), "Solve for x:", fill='black', font=font)
    draw.text((100, 200), "2x + 7 = 23", fill='black', font=math_font)
    
    draw.text((50, 280), "Show all steps and check your answer.", fill='black', font=font)
    
    # Add some workspace lines
    for i in range(5):
        y = 350 + (i * 30)
        draw.line([(50, y), (700, y)], fill='lightgray', width=1)
    
    filename = "demo_math.png"
    img.save(filename)
    print(f"✅ Created demo math problem: {filename}")
    return filename

Return Value

Returns a string containing the filename of the created image ('demo_math.png'). The function also saves the image file to the current working directory and prints a success message to stdout.

Dependencies

Usage Example

from PIL import Image, ImageDraw, ImageFont

def create_math_problem():
    img = Image.new('RGB', (800, 600), color='white')
    draw = ImageDraw.Draw(img)
    
    try:
        font = ImageFont.truetype("/usr/share/fonts/truetype/liberation/LiberationSans-Regular.ttf", 26)
        title_font = ImageFont.truetype("/usr/share/fonts/truetype/liberation/LiberationSans-Bold.ttf", 30)
        math_font = ImageFont.truetype("/usr/share/fonts/truetype/liberation/LiberationMono-Regular.ttf", 28)
    except:
        font = ImageFont.load_default()
        title_font = ImageFont.load_default()
        math_font = ImageFont.load_default()
    
    draw.text((50, 50), "Algebra Problem", fill='black', font=title_font)
    draw.line([(45, 90), (250, 90)], fill='black', width=2)
    draw.text((50, 140), "Solve for x:", fill='black', font=font)
    draw.text((100, 200), "2x + 7 = 23", fill='black', font=math_font)
    draw.text((50, 280), "Show all steps and check your answer.", fill='black', font=font)
    
    for i in range(5):
        y = 350 + (i * 30)
        draw.line([(50, y), (700, y)], fill='lightgray', width=1)
    
    filename = "demo_math.png"
    img.save(filename)
    print(f"✅ Created demo math problem: {filename}")
    return filename

# Usage
output_file = create_math_problem()
print(f"Math problem saved to: {output_file}")

Best Practices

• The function has no parameters and always creates the same math problem - consider parameterizing if you need variety
• The output filename is hardcoded as 'demo_math.png' and will overwrite existing files with the same name
• Font loading uses a try-except block to gracefully fall back to default fonts if Liberation fonts are not available
• The function prints to stdout - consider removing or making this optional for library usage
• Ensure write permissions exist in the current directory before calling
• The function returns the filename string, which can be used for further processing or verification
• Image dimensions (800x600) and all positioning values are hardcoded - consider making these configurable for reusability
