ComfyUI Node: Get Images From Batch Ranged

Get Images From Batch Ranged:

The GetImagesFromBatchRanged_F2 node is designed to extract a specific range of images from a batch based on percentage values. This node is particularly useful when you want to focus on a subset of images within a larger collection, allowing for more targeted processing or analysis. By specifying the start and end percentages, you can precisely control which portion of the image batch is selected, making it a versatile tool for workflows that require dynamic image selection. This functionality is beneficial in scenarios where you need to process only a segment of a dataset, such as when working with time-lapse sequences or when you want to apply different processing techniques to different parts of a batch.

Get Images From Batch Ranged Input Parameters:

images

This parameter represents the batch of images from which a range will be extracted. It is the primary input and should be a collection of images that you want to process. The node will operate on this batch to select a subset based on the specified percentage range.

start_percent

The start_percent parameter determines the starting point of the image range to be extracted, expressed as a percentage of the total batch size. It allows you to specify where the selection should begin, with a minimum value of 0.00 and a maximum of 1.00. The default value is 0.00, meaning the selection starts from the beginning of the batch. Adjusting this value lets you skip a portion of the initial images in the batch.

end_percent

The end_percent parameter specifies the endpoint of the image range to be extracted, also expressed as a percentage of the total batch size. It defines where the selection should end, with a minimum value of 0.00 and a maximum of 1.00. The default value is 1.00, indicating that the selection extends to the end of the batch. By modifying this value, you can exclude a portion of the images at the end of the batch from the selection.

Get Images From Batch Ranged Output Parameters:

images

The output is a subset of the original batch of images, determined by the specified start and end percentages. This output allows you to work with a focused selection of images, which can be further processed or analyzed according to your needs. The extracted images maintain the same format and structure as the input batch, ensuring compatibility with subsequent processing steps.

Get Images From Batch Ranged Usage Tips:

• To extract the first half of an image batch, set start_percent to 0.00 and end_percent to 0.50.
• For selecting the last quarter of a batch, configure start_percent to 0.75 and end_percent to 1.00.
• Ensure that the start_percent is less than the end_percent to avoid an empty selection.

Get Images From Batch Ranged Common Errors and Solutions:

Invalid percentage range

• Explanation: The start_percent is greater than or equal to end_percent, resulting in an invalid range.
• Solution: Adjust the start_percent and end_percent values to ensure that start_percent is less than end_percent.

Empty image batch

• Explanation: The input images parameter is empty, leading to no images being available for selection.
• Solution: Verify that the input batch contains images before using this node.

Percentage out of bounds

• Explanation: The start_percent or end_percent values are set outside the allowed range of 0.00 to 1.00.
• Solution: Ensure that both start_percent and end_percent are within the valid range of 0.00 to 1.00.
