ComfyUI Node: Splitting a long image into sections

Splitting a long image into sections:

The SplitLongMask node is designed to divide a long mask into multiple smaller masks based on a specified count. This is particularly useful when working with large images or masks that need to be processed in smaller, more manageable sections. By splitting the mask, you can apply different operations or effects to each segment independently, which can enhance the flexibility and efficiency of your workflow. The node ensures that the mask is divided evenly, and if the mask's height is not perfectly divisible by the count, it adjusts accordingly to maintain the integrity of the mask.

Splitting a long image into sections Input Parameters:

long_mask

The long_mask parameter represents the input mask that you want to split. This mask is typically a large, single-dimensional array that needs to be divided into smaller sections for further processing. The mask should be in a format that the node can interpret and manipulate.

count

The count parameter specifies the number of smaller masks you want to create from the original long mask. It determines how many segments the long mask will be divided into. The value of count must be an integer between 1 and 1024, inclusive. The default value is 1, which means no splitting will occur. Adjusting this value allows you to control the granularity of the mask segments.

Splitting a long image into sections Output Parameters:

MASK

The output parameter MASK is a list of smaller masks generated from the original long mask. Each mask in the list corresponds to a segment of the original mask, divided based on the specified count. These smaller masks can be used independently for various image processing tasks, providing greater flexibility and control over your workflow.

Splitting a long image into sections Usage Tips:

• To achieve optimal results, ensure that the count parameter is set to a value that evenly divides the height of the original mask. This will prevent any potential issues with uneven mask segments.
• Use the SplitLongMask node when you need to apply different effects or operations to specific sections of a large mask. This can help in creating more detailed and complex image manipulations.
• Experiment with different count values to find the best segmentation for your specific use case. Smaller segments may provide more control, while larger segments can be processed more quickly.

Splitting a long image into sections Common Errors and Solutions:

"Invalid mask shape"

• Explanation: This error occurs when the input mask does not have a valid shape that can be processed by the node.
• Solution: Ensure that the input mask is a properly formatted array with the correct dimensions. Verify that the mask is not empty and has the expected height and width.

"Count value out of range"

• Explanation: This error occurs when the count parameter is set to a value outside the allowed range (1 to 1024).
• Solution: Adjust the count parameter to a value within the specified range. The default value is 1, and the maximum allowed value is 1024.

"Mask height not divisible by count"

• Explanation: This error occurs when the height of the mask is not evenly divisible by the count value, leading to uneven mask segments.
• Solution: Choose a count value that evenly divides the height of the mask. If this is not possible, the node will adjust the segmentation to maintain the integrity of the mask, but it is best to select a compatible count value.
