How It Works

This node blends a QR code with a background image using AI-powered artistic generation from Quick Blend V4. It takes your QR code and background image, then applies the prompt to create an aesthetically pleasing artistic QR code that maintains scannability while looking visually appealing. The qr_strength parameter controls how prominent the QR code pattern remains in the final artistic output, balancing aesthetics with functionality.

Usage Examples

Example 1: Creating a Nature-Themed QR Code

Input:

prompt: "A beautiful forest landscape with trees and sunlight"
background_url: "https://example.com/forest-background.jpg"
qr_code_url: "https://example.com/my-qr-code.png"
qr_strength: 0.6
width: 768
height: 768

Output:

image: "https://pixelml.com/output/artistic-qr-forest-12345.png"

Example 2: Corporate Branding QR Code

Input:

prompt: "Modern minimalist design with blue and white corporate colors, professional tech aesthetic"
background_url: "https://example.com/brand-background.jpg"
qr_code_url: "https://example.com/company-qr.png"
negative_prompt: "cluttered, messy, unprofessional, colorful"
qr_strength: 0.7
seed: 42
batch_size: 3

Output:

Example 3: Event Promotional QR Code

Input:

prompt: "Vibrant music festival atmosphere with neon lights and energy"
background_url: "https://example.com/festival-bg.jpg"
qr_code_url: "https://example.com/event-qr.png"
negative_prompt: "dull, boring, gray"
qr_strength: 0.5
width: 1024
height: 1024
caption: "music notes"

Output:

Common Use Cases

• Marketing Campaigns: Create eye-catching QR codes for advertisements, posters, and promotional materials

• Business Cards: Generate unique artistic QR codes that reflect your brand identity

• Event Tickets: Design memorable QR codes for concerts, conferences, and special events

• Product Packaging: Enhance product labels with aesthetically pleasing scannable codes

• Restaurant Menus: Create themed QR codes that match restaurant decor and ambiance

• Social Media Profiles: Generate shareable artistic QR codes linking to profiles or content

• Art Installations: Incorporate functional QR codes into artistic works and exhibitions

Error Handling

Error Type	Cause	Solution
Invalid Image URL	Background or QR code URL is inaccessible or malformed	Verify that both image URLs are valid and publicly accessible
QR Code Too Weak	qr_strength value is too low, making QR code unscannable	Increase qr_strength to 0.6 or higher to maintain scannability
Invalid Dimensions	Width or height values are outside acceptable range	Use dimensions between 512 and 2048 pixels for best results
Generation Timeout	Complex prompt or large batch size causing timeout	Reduce batch_size or simplify the prompt
API Limit Exceeded	Too many requests to PixelML API	Wait before making additional requests or check your API quota
Invalid Seed Value	Seed value is outside acceptable range	Use a positive integer value for the seed parameter
Poor Blend Quality	Conflicting prompt and background image styles	Ensure prompt description aligns with background image content

Notes

• QR Code Scannability: Always test the generated QR code with multiple scanners to ensure it remains functional. A qr_strength of 0.6-0.7 typically provides the best balance.

• Image Quality: Use high-resolution background images (at least 1024x1024) for best results and clearer QR code integration.

• Prompt Engineering: Detailed, descriptive prompts produce better results. Include style, colors, mood, and specific elements you want.

• Batch Generation: Use batch_size to generate multiple variations and select the best one that maintains QR functionality.

• Seed Reproducibility: Save the seed value if you want to regenerate the same artistic style with different parameters later.

• Negative Prompts: Use negative prompts to avoid unwanted elements that might interfere with QR code readability.

• Testing: Always test the final QR code across different devices and scanning apps before using in production.

• File Format: The output image is typically in PNG format with transparent background support for better integration.
