ComfyUI Node: LayerUtility: Create QRCode

LayerUtility: Create QRCode:

The LayerUtility: CreateQRCode node is designed to generate QR codes from text input, providing a convenient way to encode information into a scannable format. This node is particularly useful for embedding URLs, contact information, or any other text data into a QR code, which can then be easily shared or printed. The node allows you to customize the size and border of the QR code, ensuring that it meets your specific requirements. By leveraging this node, you can create high-quality QR codes that are both functional and visually appealing, making it an essential tool for various applications, from marketing materials to personal projects.

LayerUtility: Create QRCode Input Parameters:

size

The size parameter determines the dimensions of the generated QR code in pixels. It allows you to specify the overall size of the QR code, ensuring it fits your intended use case. The minimum value is 4, the maximum value is 99999, and the default value is 512. Adjusting this parameter will scale the QR code accordingly, with larger sizes providing better readability at the cost of increased file size.

border

The border parameter sets the width of the border around the QR code. This border helps to isolate the QR code from its surroundings, improving its scannability. The minimum value is 1, the maximum value is 10, and the default value is 1. Increasing the border size can enhance the QR code's visibility, especially when placed on busy backgrounds.

text

The text parameter is where you input the text data that you want to encode into the QR code. This can be any string, such as a URL, contact information, or a plain text message. The default value is an empty string, and it supports multiline input, allowing you to encode longer texts if needed. The content of this parameter directly affects the information stored in the QR code.

LayerUtility: Create QRCode Output Parameters:

image

The image output parameter provides the generated QR code as an image. This image can be used in various applications, such as embedding in documents, printing on materials, or sharing digitally. The output is a high-quality image that accurately represents the encoded text, ensuring reliable scanning and decoding.

LayerUtility: Create QRCode Usage Tips:

• To ensure the QR code is easily scannable, use a size that is appropriate for the intended display medium. Larger sizes are better for printing, while smaller sizes may suffice for digital use.
• Adjust the border size to improve the QR code's visibility, especially if it will be placed on a complex or colorful background.
• When encoding URLs or other long texts, ensure the text is correctly formatted and free of errors to avoid issues during scanning.

LayerUtility: Create QRCode Common Errors and Solutions:

"Cannot generate QR code: Text is too long"

• Explanation: The text input exceeds the maximum capacity for the QR code version being used.
• Solution: Try reducing the length of the text or breaking it into multiple QR codes. Alternatively, consider using a higher version of the QR code if supported.

"Invalid size parameter"

• Explanation: The size parameter is set to a value outside the allowed range.
• Solution: Ensure the size parameter is within the range of 4 to 99999 pixels.

"Invalid border parameter"

• Explanation: The border parameter is set to a value outside the allowed range.
• Solution: Ensure the border parameter is within the range of 1 to 10.

"Text input is empty"

• Explanation: The text parameter is empty, and there is no data to encode into the QR code.
• Solution: Provide a valid text input to generate the QR code.
