ComfyUI Node: Empty Latent Image (Aspect Ratio+)

Empty Latent Image (Aspect Ratio+):

The EmptyLatentImageARAdvanced node is designed to generate empty latent images with advanced aspect ratio control, providing a flexible and efficient way to create latent space representations for AI art generation. This node allows you to specify both a primary and a base resolution, along with an aspect ratio, step size, and batch size, enabling the creation of latent images that can be tailored to specific artistic needs. By offering control over these parameters, the node helps in generating latent images that are optimized for various creative processes, ensuring that the resulting images align with the desired dimensions and quality.

Empty Latent Image (Aspect Ratio+) Input Parameters:

resolution

The resolution parameter defines the primary resolution of the latent image. It determines the overall size of the generated latent image. The value must be an integer, with a default of 512, a minimum of 16, and a maximum defined by MAX_RESOLUTION. The resolution can be adjusted in steps of 8. Higher resolutions result in larger and more detailed latent images, but also require more computational resources.

base_resolution

The base_resolution parameter sets the base resolution for the latent image, which is used as a reference for certain operations. Similar to the resolution parameter, it must be an integer with a default of 512, a minimum of 16, and a maximum defined by MAX_RESOLUTION. The base resolution can also be adjusted in steps of 8. This parameter is useful for maintaining consistency in image dimensions across different stages of the creative process.

ratio

The ratio parameter specifies the aspect ratio of the latent image. It is a floating-point value with a default of 1.0, a minimum defined by MIN_RATIO, and a maximum defined by MAX_RATIO, adjustable in steps of 0.001. The aspect ratio determines the proportional relationship between the width and height of the image, allowing for the creation of images with various shapes and orientations.

step

The step parameter controls the step size for calculating the dimensions of the latent image. It is an integer with a default value of 64, a minimum of 8, and a maximum of 128, adjustable in steps of 8. The step size influences the granularity of the dimension calculations, affecting the final size and structure of the latent image.

batch_size

The batch_size parameter defines the number of latent images to generate in a single batch. It is an integer with a default value of 1, a minimum of 1, and a maximum of 4096. This parameter is crucial for batch processing, enabling the generation of multiple latent images simultaneously, which can significantly speed up the workflow for large-scale projects.

Empty Latent Image (Aspect Ratio+) Output Parameters:

latent

The latent output parameter represents the primary latent image generated by the node. It is a tensor containing the latent space representation of the image, structured according to the specified resolution, aspect ratio, and batch size. This output is essential for further processing and manipulation in the AI art generation pipeline.

base_latent

The base_latent output parameter provides the base latent image, which serves as a reference or starting point for additional operations. Similar to the latent output, it is a tensor that reflects the base resolution and other specified parameters. This output is useful for maintaining consistency and coherence in the generated images, especially when multiple stages of processing are involved.

Empty Latent Image (Aspect Ratio+) Usage Tips:

• Adjust the resolution and base_resolution parameters to match the desired output size and quality, keeping in mind the computational resources available.
• Use the ratio parameter to experiment with different aspect ratios, which can help in creating unique and varied image compositions.
• Set the step parameter to control the granularity of the dimension calculations, which can impact the final structure and detail of the latent image.
• Increase the batch_size parameter for batch processing to generate multiple latent images simultaneously, optimizing the workflow for large-scale projects.
