ComfyUI Node: Batch Images

Batch Images:

The BatchImages node is designed to efficiently combine multiple image inputs into a single batch, which is particularly useful for processing multiple images simultaneously in AI art generation workflows. This node automatically handles images of varying sizes by resizing them to match the dimensions of the first image in the batch, ensuring consistency and compatibility. The resizing is performed using bilinear upscaling with centered alignment, which maintains the quality of the images while adjusting their dimensions. This functionality is crucial for artists and developers who need to manage and process large sets of images in a streamlined manner, as it simplifies the workflow by automating the batching process and ensuring that all images are uniformly sized for further processing.

Batch Images Input Parameters:

No specific input parameters

The BatchImages node does not require specific input parameters to be defined in advance. Instead, it dynamically accepts a variable number of image inputs. This flexibility allows you to input any number of images without needing to specify them beforehand, making it adaptable to different use cases and workflows. The node automatically identifies and processes all connected image tensors, ensuring that they are batched together efficiently.

Batch Images Output Parameters:

images

The output of the BatchImages node is a single batched image tensor, labeled as images. This output contains all the input images concatenated along the batch dimension, effectively creating a multi-image batch. The batched tensor is ready for further processing or analysis, allowing you to apply subsequent operations to the entire set of images simultaneously. This output is essential for workflows that require batch processing, as it consolidates multiple images into a single, manageable unit.

Batch Images Usage Tips:

• Ensure that all input images are connected to the node, as it will automatically process and batch all available image tensors.
• Use this node when you need to process multiple images in a consistent manner, as it handles resizing and batching automatically, saving you time and effort.

Batch Images Common Errors and Solutions:

Mismatched image dimensions

• Explanation: If the input images have different dimensions, the node will resize them to match the first image's dimensions.
• Solution: Ensure that the first image in the batch is of the desired size, as all other images will be resized to match it.

No images provided

• Explanation: If no images are connected to the node, it will default to a zero image to prevent crashes.
• Solution: Make sure to connect at least one image to the node to avoid this fallback behavior.
