Product QR Code Generator

A utility for generating product QR codes that encode product information and save them as PNG images with custom colors.

Capabilities

QR Code Generation and PNG Output

Generate QR codes for product URLs and save them as PNG image files. The QR codes should be generated with appropriate size and border settings for easy scanning.

• Generates a QR code for the URL "https://example.com/product/12345" and saves it to "product_qr.png" @test
• Generates a QR code for the URL "https://shop.example.com/item/ABC-789" and saves it to "item_qr.png" @test

Custom Color Configuration

Generate QR codes with custom foreground and background colors to match branding requirements. The output should be in PNG format with the specified colors applied.

• Generates a QR code with blue foreground (RGB: 0, 0, 255) and white background (RGB: 255, 255, 255) for "https://example.com/blue" and saves to "blue_qr.png" @test
• Generates a QR code with red foreground (RGB: 255, 0, 0) and light yellow background (RGB: 255, 255, 200) for "https://example.com/red" and saves to "red_qr.png" @test

Box Size and Border Customization

Generate QR codes with configurable box sizes and border widths to control the overall dimensions and appearance of the output PNG images.

• Generates a QR code with box size 15 and border 2 for "https://example.com/large" and saves to "large_qr.png" @test
• Generates a QR code with box size 5 and border 1 for "https://example.com/small" and saves to "small_qr.png" @test
