ComfyUI Node: TileSplit (Legacy)

TileSplit (Legacy):

The TileSplit node is designed to divide a large image into smaller, more manageable tiles. This is particularly useful for processing high-resolution images that may be too large to handle in a single pass. By splitting the image into tiles, you can apply various image processing techniques to each tile individually and then recombine them if needed. This node ensures that the tiles overlap slightly, which helps in maintaining continuity and avoiding visible seams when the tiles are processed and merged back together. The primary goal of the TileSplit node is to facilitate efficient and effective image processing by breaking down large images into smaller sections.

TileSplit (Legacy) Input Parameters:

image

This parameter represents the input image that you want to split into tiles. The image should be in a format that the node can process, typically a tensor representing the image data.

tile_height

This parameter specifies the height of each tile in pixels. The default value is 64, with a minimum value of 64 and a maximum value of 4096. Adjusting this value will change the height of the tiles, impacting how the image is divided.

tile_width

This parameter specifies the width of each tile in pixels. The default value is 64, with a minimum value of 64 and a maximum value of 4096. Adjusting this value will change the width of the tiles, impacting how the image is divided.

overlap

This parameter determines the number of pixels by which adjacent tiles will overlap. The default value is 64, with a minimum value of 0 and a maximum value of 4096. Overlapping tiles help maintain continuity and avoid visible seams when the tiles are processed and merged back together.

TileSplit (Legacy) Output Parameters:

IMAGE

The output is a tensor containing the tiles generated from the input image. Each tile is a smaller section of the original image, and the tiles are arranged in a way that they can be processed individually and then recombined if needed.

TileSplit (Legacy) Usage Tips:

• Adjust the tile_height and tile_width parameters based on the resolution of your input image and the capabilities of your processing hardware. Smaller tiles may be easier to process but could increase the number of tiles generated.
• Use the overlap parameter to ensure that there are no visible seams when the tiles are recombined. A higher overlap value can help maintain continuity but may result in more redundant data.
• Ensure that the input image is in a compatible format and properly preprocessed before using the TileSplit node to avoid errors during the splitting process.

TileSplit (Legacy) Common Errors and Solutions:

"Input image is not in the correct format"

• Explanation: The input image provided is not in a format that the TileSplit node can process.
• Solution: Ensure that the input image is a tensor representing the image data. Convert the image to the appropriate format before passing it to the TileSplit node.

"Tile dimensions exceed image dimensions"

• Explanation: The specified tile_height and tile_width are larger than the dimensions of the input image.
• Solution: Adjust the tile_height and tile_width parameters to be smaller than the dimensions of the input image.

"Overlap value is too high"

• Explanation: The overlap parameter is set to a value that is too high, causing excessive overlap between tiles.
• Solution: Reduce the overlap parameter to a more reasonable value that ensures continuity without excessive redundancy.
