Is None

This function block is designed to check if an input value is None. It provides a simple way to enforce conditional logic based on the presence or absence of data.

📥 Inputs

Generic This input accepts any type of data that you want to evaluate for the None condition.

📤 Outputs

Boolean This output returns either true or false, indicating whether the input data is None.

🕹️ Controls

This block does not have any specific control widgets as it performs a straightforward check on the input.

🎨 Features

Versatile Input Handling The block accepts any type of data, making it flexible for various use cases in your workflow.

Simple Boolean Output Provides a clear boolean output to indicate the status of the input data.

📝 Usage Instructions

1. Connect Input: Link any data-producing block to the Generic input to check whether its output is None.

2. Evaluate: Run the block to receive a boolean output indicating if the input value is None.

📊 Evaluation

Upon evaluation, this function block checks the input and returns true if the input is None, otherwise, it returns false.

💡 Tips and Tricks

Conditional Logic

Utilize this block to create conditional flows in your workflows. You can connect it to And or Or blocks to build more complex logic based on the presence or absence of data.

Data Validation

Use this block to check if previous outputs are valid before proceeding with further image processing or analysis blocks, preventing runtime errors.

🛠️ Troubleshooting

Unexpected False Output

If you expected a true result but got false, verify the source connected to the input. Ensure that the data being sent is indeed None.
