ComfyUI Node: String to Label

String to Label:

The StringToLabel node is designed to convert a given string into an image label, making it a valuable tool for AI artists who need to generate text-based labels for their visual projects. This node allows you to specify the font size and the rotation angle of the text, providing flexibility in how the label appears. By transforming text into an image, it enables seamless integration of textual elements into your artwork, enhancing the overall aesthetic and communicative value of your creations. The node's primary function is to create a label image from the input string, which can then be used in various artistic and design contexts.

String to Label Input Parameters:

input

This parameter takes the string that you want to convert into a label. The text provided here will be rendered into an image, so make sure it contains the exact content you wish to display.

font_size

This parameter specifies the size of the font used to render the text. It accepts integer values with a default of 45, a minimum of 1, and a maximum of 200. Adjusting the font size will impact the readability and visual prominence of the text in the generated label.

clockwise_rotation

This parameter determines the rotation angle of the text in the label image. It accepts one of the following values: 0, 90, 180, or 270 degrees. This allows you to rotate the text to fit different design requirements or orientations within your artwork.

String to Label Output Parameters:

Label

The output is an image that contains the rendered text. This image can be used directly in your projects, allowing you to incorporate text labels seamlessly into your visual compositions. The label image is returned as a tensor that can be further processed or integrated into other nodes within your workflow.

String to Label Usage Tips:

• To ensure the text is clearly visible, choose an appropriate font size based on the length of the string and the desired prominence of the label.
• Use the rotation parameter to align the text with other elements in your design, especially if you are working with non-horizontal layouts.
• Experiment with different font sizes and rotations to achieve the best visual effect for your specific project.

String to Label Common Errors and Solutions:

Font file not found

• Explanation: The node requires a specific font file to render the text, and it may not be found at the specified path.
• Solution: Ensure that the font file exists at the specified path and is accessible. You may need to update the path to point to a valid font file.

Invalid font size

• Explanation: The font size provided is outside the acceptable range.
• Solution: Adjust the font size to be within the range of 1 to 200.

Text rendering issues

• Explanation: The text may not render correctly if the input string contains unsupported characters or formatting.
• Solution: Verify that the input string contains only supported characters and does not include any special formatting that might cause rendering issues.
