ComfyUI Node: Playbook Aspect Ratio Select (External)

Playbook Aspect Ratio Select (External):

The Playbook Aspect Ratio Select node is designed to facilitate the selection of predefined aspect ratios for your projects, particularly useful in 3D rendering and design workflows. This node provides a straightforward way to choose from a set of common aspect ratios, such as 1:1, 16:9, 9:16, 4:3, and 3:4, ensuring that your visual outputs maintain the desired proportions. By offering a simple interface to select these ratios, it helps streamline the process of setting up your canvas or render settings, allowing you to focus more on the creative aspects of your work. This node is particularly beneficial for artists and designers who need to quickly adapt their work to different display formats or project requirements without manually calculating dimensions.

Playbook Aspect Ratio Select (External) Input Parameters:

id

The id parameter is a string input that serves as a unique identifier for the node. It is used to distinguish this node from others within the same workflow. This parameter does not affect the node's execution or results directly but is essential for organizational purposes. The default value is "Node ID".

label

The label parameter is a string input that allows you to assign a descriptive label to the node. This label helps in identifying the node's purpose or role within a larger workflow, making it easier to manage complex projects. Like the id, this parameter does not impact the node's functionality but aids in clarity and organization. The default value is "Node Label".

default_value

The default_value parameter is a dropdown selection that lets you choose from a list of predefined aspect ratios: 1:1, 16:9, 9:16, 4:3, and 3:4. This parameter directly influences the output of the node by determining the aspect ratio that will be applied. The default selection is 1:1, but you can choose any of the available options to suit your project's needs.

Playbook Aspect Ratio Select (External) Output Parameters:

x

The x output parameter represents the width component of the selected aspect ratio. It is an integer value that, when paired with the y parameter, defines the horizontal dimension of the aspect ratio. This output is crucial for setting up the correct proportions in your design or rendering tasks.

y

The y output parameter represents the height component of the selected aspect ratio. It is an integer value that, along with the x parameter, defines the vertical dimension of the aspect ratio. This output ensures that your visual outputs maintain the intended proportions, which is essential for consistency across different media formats.

Playbook Aspect Ratio Select (External) Usage Tips:

• Use the default_value parameter to quickly switch between different aspect ratios when working on projects that require multiple formats, such as social media posts or video content.
• Assign meaningful id and label values to your nodes to keep your workflow organized, especially when dealing with complex projects involving multiple nodes.

Playbook Aspect Ratio Select (External) Common Errors and Solutions:

Invalid Aspect Ratio Selection

• Explanation: This error occurs if an aspect ratio is selected that is not defined in the node's aspect dictionary.
• Solution: Ensure that the default_value parameter is set to one of the predefined options: 1:1, 16:9, 9:16, 4:3, or 3:4.

Node ID or Label Not Set

• Explanation: This warning might appear if the id or label parameters are left empty, which can lead to confusion in complex workflows.
• Solution: Always provide a unique id and a descriptive label for each node to maintain clarity and organization in your project.
