ComfyUI Node: Empty Latent by Pixels (WLSH)

Empty Latent by Pixels (WLSH):

The Empty Latent by Pixels (WLSH) node is designed to generate an empty latent image based on specified pixel dimensions, aspect ratio, and orientation. This node is particularly useful for AI artists who need to create a latent space representation of an image with precise control over its resolution and aspect ratio. By providing a flexible and efficient way to generate latent images, this node helps streamline the workflow for various image processing and generation tasks, ensuring that the resulting latent images are well-suited for further manipulation or analysis.

Empty Latent by Pixels (WLSH) Input Parameters:

aspect

The aspect parameter defines the aspect ratio of the generated latent image. It is a string that specifies the ratio of width to height, such as "16:9" or "4:3". This parameter helps determine the overall shape of the latent image. Available options include "1:1", "5:4", "4:3", "3:2", "16:10", "16:9", "19:9", "21:9", "43:18", "2:1", "3:1", and "4:1".

direction

The direction parameter specifies the orientation of the latent image. It can be set to either "landscape" or "portrait". This parameter affects the width and height dimensions of the generated image, swapping them if "portrait" is selected.

megapixels

The megapixels parameter determines the total number of megapixels for the generated latent image. It is a floating-point value that ranges from 0.01 to 16.0, with a default value of 1.0. This parameter directly influences the resolution of the latent image, with higher values resulting in larger images.

batch_size

The batch_size parameter specifies the number of latent images to generate in a single batch. It is an integer value that ranges from 1 to 64, with a default value of 1. This parameter is useful for generating multiple latent images simultaneously, which can be beneficial for batch processing tasks.

Empty Latent by Pixels (WLSH) Output Parameters:

latent

The latent output parameter is a dictionary containing the generated latent image(s). The latent images are represented as tensors filled with zeros, which can be further processed or manipulated as needed.

width

The width output parameter indicates the width of the generated latent image(s) in pixels. This value is calculated based on the specified aspect ratio, megapixels, and orientation.

height

The height output parameter indicates the height of the generated latent image(s) in pixels. This value is calculated based on the specified aspect ratio, megapixels, and orientation.

Empty Latent by Pixels (WLSH) Usage Tips:

• To create a square latent image, set the aspect parameter to "1:1" and adjust the megapixels parameter to achieve the desired resolution.
• Use the direction parameter to quickly switch between landscape and portrait orientations without manually adjusting the width and height values.
• Experiment with different megapixels values to find the optimal resolution for your specific use case, keeping in mind that higher values will result in larger latent images.

Empty Latent by Pixels (WLSH) Common Errors and Solutions:

Invalid aspect ratio

• Explanation: The specified aspect ratio is not one of the available options.
• Solution: Ensure that the aspect parameter is set to one of the predefined ratios, such as "16:9" or "4:3".

Megapixels out of range

• Explanation: The megapixels value is outside the allowed range of 0.01 to 16.0.
• Solution: Adjust the megapixels parameter to a value within the valid range.

Batch size out of range

• Explanation: The batch_size value is outside the allowed range of 1 to 64.
• Solution: Set the batch_size parameter to a value within the valid range.
