ComfyUI Node: Latent Properties 🧅

Latent Properties 🧅:

The NegiTools_LatentProperties node is designed to extract and provide the dimensions of a latent image representation. This node is particularly useful for AI artists who work with latent spaces in generative models, as it allows them to easily obtain the width and height of the latent image. By understanding the dimensions of the latent image, you can better manage and manipulate the latent space for various creative tasks, such as image generation, transformation, and interpolation. The node simplifies the process of accessing latent image properties, making it more accessible for users without a deep technical background.

Latent Properties 🧅 Input Parameters:

latent

The latent parameter is the input latent image representation from which the node will extract the dimensions. This parameter is essential as it contains the latent space data that the node processes to determine the width and height. The latent input should be a dictionary with a key "samples" that holds the latent tensor. The node uses this tensor to calculate the dimensions by multiplying the shape values by 8, which is a common scaling factor in latent space representations.

Latent Properties 🧅 Output Parameters:

WIDTH

The WIDTH output parameter represents the width of the latent image. This value is derived from the shape of the latent tensor and is scaled by a factor of 8. Understanding the width of the latent image is crucial for tasks that involve spatial manipulation or alignment of latent representations.

HEIGHT

The HEIGHT output parameter represents the height of the latent image. Similar to the width, this value is calculated from the shape of the latent tensor and scaled by a factor of 8. Knowing the height of the latent image helps in various creative processes, such as resizing or transforming the latent space.

Latent Properties 🧅 Usage Tips:

• Ensure that the latent input is correctly formatted as a dictionary with a key "samples" containing the latent tensor to avoid errors.
• Use the width and height outputs to guide your manipulations of the latent space, ensuring that any transformations or interpolations maintain the correct dimensions.
• Combine this node with other latent space manipulation nodes to create complex and creative generative art workflows.

Latent Properties 🧅 Common Errors and Solutions:

Invalid latent input format

• Explanation: The latent input is not formatted correctly or does not contain the required "samples" key.
• Solution: Verify that the latent input is a dictionary with a key "samples" that holds the latent tensor. Ensure that the tensor is properly structured and accessible.

Latent tensor shape mismatch

• Explanation: The shape of the latent tensor does not match the expected dimensions, leading to incorrect width and height calculations.
• Solution: Check the shape of the latent tensor and ensure it conforms to the expected format. If necessary, reshape or preprocess the latent tensor to match the required dimensions.
